vb.net DataTable.Rows.IndexOf 怎么使用

        Dim oDatatable As DataTable = New DataTable("TestDatetable")

        For i As Integer = 1 To 5
            oDatatable.Columns.Add("Column" + i.ToString())
        Next

        For i As Integer = 1 To 10
            Dim oDataRow As DataRow = oDatatable.NewRow()
            For Each oDataColumn As DataColumn In oDatatable.Columns
                oDataRow(oDataColumn) = "行" + i.ToString()
            Next
            oDatatable.Rows.Add(oDataRow)
        Next

        For Each oDR As DataRow In oDatatable.Rows
            MsgBox(oDatatable.Rows.IndexOf(oDR))
        Next
