学无止境，精益求精
十年河东，十年河西，莫欺少年穷
用于基础返回值类型，如下：
using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Data.DataCommon { public class BaseResponse { public BaseResponse() { this.IsSuccess = false; this.ResultCode = -1; this.ResultMessage = "请求失败..."; } /// <summary> /// 返回信息 /// </summary> public string ResultMessage { get; set; } /// <summary> /// 返回编码 -1 代表失败 0代表成功 /// </summary> public int ResultCode { get; set; } /// <summary> /// 处理是否成功 /// </summary> public bool IsSuccess { get; set; } } public class BaseResponse<T> : BaseResponse { public T Data { get; set; } //public List<T> DataList { get; set; } public BaseResponse() { this.IsSuccess = false; this.ResultCode = -1; this.ResultMessage = "请求失败..."; } public BaseResponse(T data) { this.Data = data; } } public class CommonBaseResponse { #region 重置Response public static BaseResponse<T> SetResponse<T>(T Data, bool bol, string Msg = "", int cord = 0) { BaseResponse<T> response = new BaseResponse<T>(); response.Data = Data; response.IsSuccess = bol; response.ResultCode = bol == true ? 0 : -1; if (cord != 0) { response.ResultCode = cord; } response.ResultMessage = bol == true ? "请求成功..." : "请求失败..."; if (!string.IsNullOrEmpty(Msg)) { response.ResultMessage = Msg; } return response; } public static BaseResponse SetResponse(bool bol, string Msg = "", int cord = 0) { BaseResponse response = new BaseResponse(); response.IsSuccess = bol; response.ResultCode = bol == true ? 0 : -1; if (cord != 0) { response.ResultCode = cord; } response.ResultMessage = bol == true ? "请求成功..." : "请求失败..."; if (!string.IsNullOrEmpty(Msg)) { response.ResultMessage = Msg; } return response; } #endregion } }
下面我们用GET，POST请求如下：
[HttpPost] public ActionResult GetData(DataModel model) { var result = CommonBaseResponse.SetResponse(true); return Json(result, JsonRequestBehavior.DenyGet); } [HttpGet] public ActionResult GetData(string userId) { var result=CommonBaseResponse.SetResponse(true); return Json(result, JsonRequestBehavior.AllowGet); }
Ajax 请求如下：
<script src="~/Scripts/jquery-1.10.2.min.js"></script> <script type="text/javascript"> $(function () { $.get("/Home/GetData?userId=chen", function (result) { console.log(result) }) }) </script>
返回值如下：
Post请求类似，在此不再累述。
如果返回值中带有数据集合，怎么处理？
C#如下：
[HttpGet] public ActionResult GetData(string userId) { List<DataModel> list = new List<DataModel>(); list.Add(new DataModel() { userId = "081309201", userName = "Jack.Chen", userNo = "08130920701", userSex = "男" }); list.Add(new DataModel() { userId = "081309202", userName = "LiLi.Chen", userNo = "08130920702", userSex = "女" }); var result = CommonBaseResponse.SetResponse<List<DataModel>>(list,true); return Json(result, JsonRequestBehavior.AllowGet); }
返回值如下：
综上所述，如此简单。
顺便一个格式化类
public class CommonModelFunc { public static string FormatDate(Nullable<System.DateTime> date) { try { string dateString = Convert.ToDateTime(date).ToString("yyyy-MM-dd"); if (dateString != "0001-01-01") { return Convert.ToDateTime(date).ToString("yyyy-MM-dd"); } else { return ""; } } catch { return ""; } } public static string FormatDate(Nullable<System.DateTime> date,string format) { try { string dateString = Convert.ToDateTime(date).ToString("yyyy-MM-dd"); if (dateString != "0001-01-01") { return Convert.ToDateTime(date).ToString(format); } else { return ""; } } catch { return ""; } } public static string FormatStringDate(string date) { try { string dateString = Convert.ToDateTime(date).ToString("yyyy-MM-dd"); if (dateString != "0001-01-01") { return Convert.ToDateTime(date).ToString("yyyy-MM-dd"); } else { return ""; } } catch { return ""; } } public static string FormatStringDate(string date,string format) { try { string dateString = Convert.ToDateTime(date).ToString("yyyy-MM-dd"); if (dateString != "0001-01-01") { return Convert.ToDateTime(date).ToString(format); } else { return ""; } } catch { return ""; } } public static string FormatMoney(Nullable<decimal> Money) { if (Money.HasValue) { return Convert.ToDouble(Money).ToString("0.00"); } else { return ""; } } public static string FormatDateHMS(Nullable<System.DateTime> date) { try { string dateString = Convert.ToDateTime(date).ToString("yyyy-MM-dd"); if (dateString != "0001-01-01") { return Convert.ToDateTime(date).ToString("yyyy-MM-dd HH:mm:ss"); } else { return ""; } } catch { return ""; } } public static string FormatDateChineseHMS(Nullable<System.DateTime> date) { try { string dateString = Convert.ToDateTime(date).ToString("yyyy-MM-dd"); if (dateString != "0001-01-01") { return Convert.ToDateTime(date).ToString("yyyy年MM月dd日 HH时mm分"); } else { return ""; } } catch { return ""; } } }
在此，顺便介绍一个ConvertHelper的类，如下：
using System; using System.Collections; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Reflection; using System.Text; using System.Linq; using System.Text.RegularExpressions; namespace Movit.ZhaoCai.DataCommon { public static class ConvertHelper { /// <summary> /// datatow 转换Datatable /// </summary> /// <param name="drArr"></param> /// <returns></returns> public static DataTable GetDataTableByDataRows(DataRow[] drArr) { if (drArr == null || drArr.Length == 0) return null; DataTable tmp = drArr[0].Table.Clone(); // 复制DataRow的表结构 foreach (DataRow row in drArr) tmp.Rows.Add(row.ItemArray); // 将DataRow添加到DataTable中 return tmp; } public static string ToString(object value) { if (value != null) { return value.ToString(); } else { return string.Empty; } } public static int ToInt(object value) { int result = -1; if (value != null) { int.TryParse(value.ToString(), out result); } return result; } public static decimal ToDecimal(object value) { decimal val = 0; if (value == null || string.IsNullOrEmpty(value.ToString())) { } else { if (value != null && IsNumber(value.ToString())) { decimal.TryParse(value.ToString(), out val); } } return Math.Round(val, 2); } public static decimal?
