【VB.NET】ADO.Net学习（一）DataReader转换为DataSet

Public Function ConvertDataReaderToDataSet(ByVal reader As _
            SqlDataReader) As DataSet
            Dim dataSet As DataSet = New DataSet
            Dim schemaTable As DataTable = reader.GetSchemaTable()
            Dim dataTable As DataTable = New DataTable
            Dim intCounter As Integer
            For intCounter = 0 To schemaTable.Rows.Count - 1
                Dim dataRow As DataRow = schemaTable.Rows(intCounter)
                Dim columnName As String = CType(dataRow("ColumnName"), String)
                Dim column As DataColumn = New DataColumn(columnName, _
                     CType(dataRow("DataType"), Type))
                dataTable.Columns.Add(column)
            Next
            dataSet.Tables.Add(dataTable)

                For intCounter = 0 To reader.FieldCount - 1
                    dataRow(intCounter) = reader.GetValue(intCounter)
