超时已过期。之前的操作的完成的超时时间已过或服务器未响应

问题描述：

所以我有这个功能超时已过期。之前的操作的完成的超时时间已过或服务器未响应

Public Function getDataSetonDataTable(ByVal query As String, ByVal sDatabaseConnection As String) As DataTable 
    Dim dsRecordset As New DataSet 
    Dim dtReturn As DataTable 

    Try 
     open(sDatabaseConnection) 
     oConn.Open() 
    Catch ex As Exception 
     log.infoError(ex, "GET DATA SETON DATA PART 1 ON cDatabase.vb") 
     Return Nothing 
    End Try 

    Try 
     createLog("Q || " & query) 

     dsRecordset = oDatabase.ExecuteDataSet(System.Data.CommandType.Text, query) 
     dtReturn = dsRecordset.Tables(0) 
    Catch ex As Exception 
     If ex.Message.ToString = "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding." Then 
      Try 
       createLog("Query : " & query) 
       dsRecordset = oDatabase.ExecuteDataSet(System.Data.CommandType.Text, query) 
       dtReturn = dsRecordset.Tables(0) 
      Catch ex2 As Exception 
       log.infoError(ex, "GET DATA SETON DATA PART 2 ON cDatabase.vb") 
       dtReturn = Nothing 
       ErrorMessage = ex2.Message.ToString 
       MessageBox.Show(ErrorMessage, "Database Error", MessageBoxButtons.OK, MessageBoxIcon.Stop) 
      Finally 
       oConn.Close() 
      End Try 
      Return dtReturn 
     End If 
     dtReturn = Nothing 
     ErrorMessage = ex.Message.ToString 
     MessageBox.Show(ErrorMessage, "Database Error", MessageBoxButtons.OK, MessageBoxIcon.Stop) 
    Finally 
     oConn.Close() 
    End Try 
    Return dtReturn 
End Function

这是数据检索程序代码

dsRecordset = oDatabase.ExecuteDataSet(System.Data.CommandType.Text, query)

然而，如果执行复杂的查询，恰好60秒后才会出现此异常

如何将超时设置为较长时间段？
我在Visual Studio 2005中使用vb.net
在此先感谢。

受到Sql CommandTimeout set for EnterpriseLibrary的回答启发，我将查询分配给一个System.Data.Common.DbCommand变量，分配了一个超时值，并使用dbCommand变量调用ExecuteDataSet（）。
