winform 调用存储过程显示分页列表 直接贴代码吧 SqlHelperusing System;using System.Collections.Generic;using System.Linq;using System.Text;using System.Data.SqlClient;using System.Data; namespace ADMEWinForm{ class SqlHelper { private static readonly string strCon = System.Configuration.ConfigurationSettings.AppSettings["connstr"].ToString(); #region 实例化对象 /// <summary> /// 实例化对象 /// </summary> SqlConnection con = new SqlConnection(strCon); private DataSet ds; private SqlCommand cmd; private SqlDataAdapter sda; private SqlDataReader myReader; private SqlTransaction transaction; #endregion #region 检测连接是否打开 /// <summary> /// 检测连接的方法CheckConnection(),若连接是关闭的则打开SqlConnection连接 /// </summary> public void CheckConnection() { if (this.con.State == ConnectionState.Closed) { this.con.Open(); } } #endregion #region 执行SQL语句或存储过程的方法ExecuteDataSetProc() public DataSet ExecuteDataSetProc(string strSQL, int pagesize, int pageindex) { CheckConnection(); DataSet ds1 = new DataSet(); try { cmd = new SqlCommand(strSQL, con); cmd.CommandType = CommandType.StoredProcedure; SqlParameter[] para = { new SqlParameter("@PageSize", SqlDbType.Int), new SqlParameter("@PageIndex", SqlDbType.Int) }; para[0].Value = pagesize; para[1].Value = pageindex; cmd.Parameters.AddRange(para); SqlDataAdapter dap = new SqlDataAdapter(); dap.SelectCommand = cmd; dap.Fill(ds1, "TGongWen"); } catch (Exception e) { e.Message.ToString(); } finally { con.Close(); } return ds1;
