我阅读了这个问题的C++版本,但并没有真正理解它.

有人可以清楚地解释一下是否可以做到以及如何做？

为什么某些流行语言中的函数只返回一种类型的结果？

即我的意思是为什么编译器给下面的语法错误

public int int  returnTwoIntegers(){
.......

我有存储过程,我将执行其结果并将其传递到数据集并返回它,但同时我的存储过程中有一个输出参数,我也想返回,如何返回数据集和整数使用我的函数输出值,还是有更合适的方法来处理这种情况？请好好的建议,谢谢.

            Dim dbCommand As DbCommand = Nothing
            Dim retDS As DataSet = Nothing

            Try
                If dbConnection.State <> ConnectionState.Open Then
                    dbConnection.Open()
                End If

                dbCommand = GetStoredProcedureCommand("Campaign_LoadListing")
                dbCommand.Connection = dbConnection

                With objCampaignManagmentClassBLL

                    Select Case SortFilterField
                        Case "Code"
                            AddInParameter(dbCommand, "@Code", DbType.String, 50, DBNull.Value) …
