示例1: BufferClassDemo

' Example of the Buffer class methods.
Module BufferClassDemo

    ' Display the array elements from right to left in hexadecimal.
    Sub DisplayArray( arr( ) As Short )

        Console.Write( "  arr:" )
        Dim loopX     As Integer
        For loopX = arr.Length - 1 To 0 Step -1
            Console.Write( " {0:X4}", arr( loopX ) )
        Next loopX
        Console.WriteLine( )
    End Sub

    Sub Main( )

        ' This array is to be modified and displayed.
        Dim arr( ) As Short = { 258, 259, 260, 261, 262, 263, 264, _

输出：

Note: The array is displayed from right to left.

Initial values of array:

arr: 010F 010E 010D 010C 010B 010A 0109 0108 0107 0106 0105 0104 0103 0102

Buffer.ByteLength( arr ): 28

Call these methods:
Buffer.BlockCopy( arr, 5, arr, 16, 9 ),
Buffer.SetByte( arr, 7, 170 ).

Final values of array:

arr: 010F 0101 0801 0701 0601 0501 0109 0108 0107 0106 AA05 0104 0103 0102

Buffer.GetByte( arr, 26 ): 15
