示例1: TestGetValues
Private Sub TestGetValues(ByVal reader As DataTableReader)
' Given a DataTableReader, use the GetValues
' method to retrieve a full row of data.
' Test the GetValues method, passing in an array large
' enough for all the columns.
Dim values(reader.FieldCount - 1) As Object
Dim fieldCount As Integer = reader.GetValues(values)
Console.WriteLine("reader.GetValues retrieved {0} columns.", _
fieldCount)
For i As Integer = 0 To fieldCount - 1
Console.WriteLine(values(i))
Next
Console.WriteLine()
' Now repeat, using an array that may contain a different
' number of columns than the original data. This should work correctly,
' whether the size of the array is larger or smaller than
' the number of columns.
' Attempt to retrieve three columns of data.
