问题描述

你好



我正试图翻转数据集，以便在ASP.NET中使用VB.NET翻转我的gridview



我正在使用此代码

Hello

I'm trying to flip Dataset so as to flip my gridview in ASP.NET using VB.NET

I'm using this code

Public Function FlipDataSet(ByVal my_DataSet As DataSet) As DataSet
        Dim ds As New DataSet()


        For Each dt As DataTable In my_DataSet.Tables
            Dim table As New DataTable()

            For i As Integer = 0 To dt.Rows.Count
                table.Columns.Add(Convert.ToString(i))
            Next i
            Dim r As DataRow
            For k As Integer = 0 To dt.Columns.Count - 1
                r = table.NewRow()
                r(0) = dt.Columns(k).ToString()
                For j As Integer = 1 To dt.Rows.Count
                    r(j) = dt.Rows(j - 1)(k)
                Next j
                table.Rows.Add(r)
            Next k

            ds.Tables.Add(table)
        Next dt

        Return ds
    End Function

错误已开启（转换）

推荐答案

您在类名称转换的某处具有受保护的方法这会隐藏Convert类。你可以使用完整的命名空间告诉编译器在哪里找到Convert：

You have protected method somewhere in the class that is named Convert this hides the Convert class. You can either use full namespace to tell the compiler where to find Convert:

System.Convert.ToString(i)

或直接在整数值上直接调用ToString：

or simply call ToString on the integer value directly:

i.ToString()
