--1:存储过程返回DataSet 的例子:
  
  C# 代码 :通用类
  
  public static int SingleSTCD(DateTime StartTime,DateTime EndTime,int SMTP,string JL,string STDCD,string STCDSTR, out DataSet ds )
  {
  int ret=0;
  ds=null;
  
  OleDbConnection Constring=new OleDbConnection(Appraise.ConStr);
  OleDbCommand cmd=new OleDbCommand("P_Get_STCD_SingleAppraise_XunQi",Constring);
  try
  {
  OleDbDataAdapter ada=new OleDbDataAdapter();
  cmd.CommandType=CommandType.StoredProcedure;
  cmd.Parameters.Add("@StartTime", OleDbType.DBTimeStamp).Value=StartTime ;
  cmd.Parameters.Add("@EndTime", OleDbType.DBTimeStamp).Value=EndTime ;
  cmd.Parameters.Add("@SMTP", OleDbType.Integer).Value=SMTP ;
  cmd.Parameters.Add("@JL", OleDbType.VarChar, 50).Value=JL ;
  //cmd.Parameters.Add("@STDCD", OleDbType.VarChar, 50).Value=STDCD ; //评价标准
  cmd.Parameters.Add("@STCDSTR", OleDbType.VarChar, 8000).Value=STCDSTR ;
  
  System.Data.DataSet data = new DataSet();
  ada.SelectCommand = cmd;
  ada.Fill(data,"table");
  ds = data;
  ret=ds.Tables[0].Rows.Count;
  if ( ret ==-1 )
  {
  return -1000; //无数据
  }
  else
  {
  return ret;
  }
  
  }
  catch(Exception e)
  {
  //数据库操作发生错误,返回错误代码
  System.Diagnostics.Debug.WriteLine(e.Message);
  return -1001;
  }
  finally
  {
  Constring.Close();
  cmd.Parameters.Clear();
  }
  
  VB.net 调用:
  
  Private Sub BindingDataGrid_Query()
  Dim ds As System.Data.DataSet
  Zehua.Water.Appraise.SingleSTCD("1999-5-1", "1999-9-1", 1, "Ⅲ", "", "50181300,50185050,50181350,50185100,50185150,50185200,50185250,50181200,50185150,51282300", ds)
  DataGrid_Query.DataSource = ds
  DataGrid_Query.DataBind()
  End Sub
  
  --1:存储过程返回数组字符串
  
  REM 执行存储过程,返回一数组
  Public Shared Function ExecuteSP_ToArrary(ByVal sConnString As String, ByVal Text_STCD As String, ByVal Text_TIME As String, ByRef TableInfo() As String)
  Dim conn As OleDbConnection = New OleDbConnection(sConnString)
  ReDim TableInfo(2)
  
  Try
  conn.Open()
  Dim command As OleDbCommand = New OleDbCommand("P_GET_QueryValue", conn)
  command.CommandType = CommandType.StoredProcedure
  Dim sqlParams() As OleDbParameter = {New OleDbParameter("@STCD", Text_STCD), New OleDbParameter("@GETM", Text_TIME), New OleDbParameter("@ReturnValue", OleDbType.VarChar, 8000), New OleDbParameter("@ReturnColumnCode", OleDbType.VarChar, 8000), New OleDbParameter("@ReturnColumnName", OleDbType.VarChar, 8000)}
  sqlParams(2).Direction = ParameterDirection.Output
  sqlParams(3).Direction = ParameterDirection.Output
  sqlParams(4).Direction = ParameterDirection.Output
  Dim i As Integer = 0
  While i < sqlParams.Length
  command.Parameters.Add(sqlParams(i))
  i += 1
  End While
  command.ExecuteNonQuery()
  If sqlParams(2).Value.ToString().Length > 0 Then
  TableInfo(0) = sqlParams(2).Value.ToString()
  Else
  End If
  
  If sqlParams(3).Value.ToString().Length > 0 Then
  TableInfo(1) = sqlParams(3).Value.ToString()
  Else
  End If
  
  If sqlParams(4).Value.ToString().Length > 0 Then
  TableInfo(2) = sqlParams(4).Value.ToString()
  Else
  End If
  
  Catch ex As Exception
  ZeHua.Log.exNoteBugs(ex, "SigleStcdEdit.aspx") 'sb.Append(ex.Message)
  Finally
  conn.Close()
  End Try
  
  End Function
