.NET MVC+ EF+调用存储过程 多表联查以及VIEW列表显示

直接上干活，至于网上的一大堆处理方式不予评论，做好自己的就是最好的，供大家不走弯路

1、view页面

<link href="~/Content/bootstrap.css" rel="stylesheet" />


    <div class="well">
        <table class="table">
            <tr>
                <th>用户名</th>
                <th>地址</th>
                <th>订单编号</th>
                <th>城市代号</th>
                <th>时间</th>
                <th>订单状态</th>
            </tr>
           
            @foreach (var item in ViewBag.dyObject)
            {
                <tr>
                    <td>@item.UserName </td>
                    <td>@item.LocalAddress </td>
                    <td>@item.BargainOrderCode </td>
                    <td>@item.CityCode </td>
                    <td>@item.UpdateTime </td>
                    <td>@item.OrderStatus </td>

                </tr>

            }
        </table>

    </div>

 2、Controller 控制器代码

 public async Task<ActionResult> UserOrder()
       {
         #region 使用存储过程实现多表联查VIEW显示

        int lastID = 0;
        int pageSize = 10;
        SqlParameter[] Param =
            {

                    new SqlParameter("@lastID", System.Data.SqlDbType.Int),
                    new SqlParameter("@pageSize", System.Data.SqlDbType.Int)

            };

           
            if (lastID< 0)
            {
                Param[0].Value = DBNull.Value;
            }
            else
            {
                Param[0].Value = lastID;
            }

            if (pageSize< 0)
            {
                Param[1].Value = DBNull.Value;
            }
            else
            {
                Param[1].Value = pageSize;
            }

            
            var data = await _DbContext.Exec_SpAsync("SP_GetUserOrderList", Param);
            //foreach (Dictionary<string, object> item in data)
            //{

            //    string UserName = item["UserName"].ToString();
            //    string LocalAddress = item["LocalAddress"].ToString();
            //    string BargainOrderCode = item["BargainOrderCode"].ToString();
            //    string CityCode = item["CityCode"].ToString();
            //    DateTime UpdateTime = Convert.ToDateTime(item["UpdateTime"]);
            //    int OrderStatus = Convert.ToInt32(item["OrderStatus"]);
            //}
            List<dynamic> userList = new List<dynamic>();
           
            foreach (Dictionary<string, object> item in data)
            {
                //userList.Add(new
                //{
                //    UserName = item["UserName"].ToString(),
                //    LocalAddress = item["LocalAddress"].ToString(),
                //    BargainOrderCode = item["BargainOrderCode"].ToString(),
                //    CityCode = item["CityCode"].ToString(),
                //    UpdateTime =Convert.ToDateTime(item["UpdateTime"]),
                //    OrderStatus =Convert.ToInt32(item["OrderStatus"])

                //  });      
                
                dynamic dyObject = new ExpandoObject();
                dyObject.UserName = item["UserName"].ToString();
                dyObject.LocalAddress = item["LocalAddress"].ToString();
                dyObject.BargainOrderCode = item["BargainOrderCode"].ToString();
                dyObject.CityCode = item["CityCode"].ToString();
                dyObject.UpdateTime = Convert.ToDateTime(item["UpdateTime"]);
                dyObject.OrderStatus = Convert.ToInt32(item["OrderStatus"]);
                userList.Add(dyObject);
            }
            ViewBag.dyObject = userList;
            return View();
            #endregion
          }

 3、EF中多表查询操作的存储过程通用调用方法

/// <summary>
    /// 存储共用
    /// </summary>
    public static class StorageCommon
    {
        /// <summary>
        /// 带有参数的存储过程公共方法  获取信息集合  以及返回空值处理
        /// </summary>
        /// <param name="db"></param>
        /// <param name="sql"></param>
        /// <param name="sqlParams"></param>
        /// <returns></returns>
        public async static Task<ArrayList> Exec_SpAsync(this DefaultDbContext db, string sql, SqlParameter[] sqlParams)
        {

            using (var cmd = db.Database.Connection.CreateCommand())
            {
                await db.Database.Connection.OpenAsync();
                cmd.CommandText = sql;
                cmd.CommandType = System.Data.CommandType.StoredProcedure;
                cmd.Parameters.AddRange(sqlParams);
                var dr = await cmd.ExecuteReaderAsync();
                var columnSchema = dr.GetColumnSchema();
                var data = new ArrayList();
                while (await dr.ReadAsync())
                {
                    var item = new Dictionary<string, object>();
                    foreach (var kv in columnSchema)
                    {
                        if (kv.ColumnOrdinal.HasValue)
                        {
                            var itemVal = dr.GetValue(kv.ColumnOrdinal.Value);
                            item.Add(kv.ColumnName, itemVal.GetType() != typeof(DBNull) ? itemVal : "");
                        }
                    }
                    data.Add(item);
                }
                dr.Dispose();
                return data;
            }
        }
完善后代码：

 public async static Task<ArrayList> Exec_SpAsync(this DefaultDbContext db, string sql, SqlParameter[] sqlParams)
        {
            var data = new ArrayList();
           DbDataReader dr=null ;
            try
            {  
                using (var cmd = db.Database.Connection.CreateCommand())
                {
                    await db.Database.Connection.OpenAsync();
                    cmd.CommandText = sql;
                    cmd.CommandType = System.Data.CommandType.StoredProcedure;
                    cmd.Parameters.AddRange(sqlParams);
                    //var dr = await cmd.ExecuteReaderAsync();
                     dr = await cmd.ExecuteReaderAsync();
                    var columnSchema = dr.GetColumnSchema();
                    
                    while (await dr.ReadAsync())
                    {
                        var item = new Dictionary<string, object>();
                        foreach (var kv in columnSchema)
                        {
                            if (kv.ColumnOrdinal.HasValue)
                            {
                                var itemVal = dr.GetValue(kv.ColumnOrdinal.Value);
                                item.Add(kv.ColumnName, itemVal.GetType() != typeof(DBNull) ? itemVal : "");
                            }
                        }
                        data.Add(item);
                    }
                }
            }
            catch (Exception ex)
            {

                _Logger.Error("查询数据" + ex.Message);
                //throw new Exception("查询失败." + ex.Message);
            }
            finally
            {
                dr.Dispose();
            }
            
                return data;
            
        }

       /// <summary>
        /// 异步执行带有参数的存储过程公共方法  增删改操作以及返回带有输出的参数
        /// </summary>
        /// <param name="db"></param>
        /// <param name="sql"></param>
        /// <param name="sqlParams"></param>
        /// <returns></returns>
        public async static Task<int> ExecuteNonQueryAsync(this DefaultDbContext db, string sql, SqlParameter[] sqlParams)
        {
            int numint;


            using (var cmd = db.Database.Connection.CreateCommand())
            {
                await db.Database.Connection.OpenAsync();
                cmd.CommandText = sql;
                cmd.CommandType = System.Data.CommandType.StoredProcedure;
                cmd.Parameters.AddRange(sqlParams);
                
                numint = await cmd.ExecuteNonQueryAsync();
                cmd.Connection.Close();
            }

            return numint;
        }

完善后代码：

        {
            int numint=0;
            using (var cmd = db.Database.Connection.CreateCommand())

                    await db.Database.Connection.OpenAsync();
                    cmd.CommandText = sql;
                    cmd.CommandType = System.Data.CommandType.StoredProcedure;
                    cmd.Parameters.AddRange(sqlParams);

                    numint = await cmd.ExecuteNonQueryAsync();
                    cmd.Connection.Close();
                    
                }
                catch (Exception ex)
                {                   
                    _Logger.Error("执行数据" + ex.Message);
                    //throw new Exception("提交失败." + ex.Message);
                }
                finally

                return numint;
                
          }
        }

    }

 4、存储过程

CREATE PROCEDURE [dbo].[SP_GetUserOrderList] 
( 
   
   @lastID int=0,  --当前页数
   @pageSize int=10 --每页显示记录数
   
 )
    
AS
   --declare  @rt_code int;  --声明变量
  
  BEGIN
   
   begin transaction
    begin try
    BEGIN

    

    SELECT  DISTINCT top (@pageSize)  -- CONVERT(varchar(100), order.UpdateTime, 20) AS UpdateTime
        * FROM    UserInfo_test usertest
        LEFT JOIN  TRA_BargainOrder_Test  ordertest 
         ON usertest.Id=ordertest.UserID 
         
       
      where (( @lastID > 0 AND usertest.Id < @lastID) OR @lastID=0 )  
    --  and CONVERT(varchar(100), MB.AddTime, 23)>CONVERT(varchar(100), @StartTime, 23) 
    --AND CONVERT(varchar(100), MB.AddTime, 23)<CONVERT(varchar(100), @EndTime, 23) 
    
      ORDER BY ordertest.UpdateTime DESC; 
END
   commit transaction
  end try 
    ----------------------------------------------------------------------------------------------------------------------------

begin catch

 print '执行存储异常'
