示例1: ReadWriteByte
Sub ReadWriteByte()
' Allocate unmanaged memory.
Dim elementSize As Integer = 1
Dim unmanagedArray As IntPtr = Marshal.AllocHGlobal(10 * elementSize)
' Set the 10 elements of the C-style unmanagedArray
For i As Integer = 0 To 9
Marshal.WriteByte(unmanagedArray, i * elementSize, CType(i + 1, Byte))
Next i
Console.WriteLine("Unmanaged memory written.")
Console.WriteLine("Reading unmanaged memory:")
' Print the 10 elements of the C-style unmanagedArray
For i As Integer = 0 To 9
Console.WriteLine(Marshal.ReadByte(unmanagedArray, i * elementSize))
Next i
Marshal.FreeHGlobal(unmanagedArray)
Console.WriteLine("Done. Press Enter to continue.")
Console.ReadLine()
End Sub示例2: Example
' 導入命名空間
Imports System.Runtime.InteropServices
Module Example
Sub Main()
' Allocate 1 byte of unmanaged memory.
Dim hGlobal As IntPtr = Marshal.AllocHGlobal(1)
' Create a new byte.
Dim b As Byte = 1
Console.WriteLine("Byte written to unmanaged memory: {0}", b)
' Write the byte to unmanaged memory.
Marshal.WriteByte(hGlobal, b)
' Read byte from unmanaged memory.
Dim c As Byte = Marshal.ReadByte(hGlobal)
Console.WriteLine("Byte read from unmanaged memory: {0}", c)
' Free the unmanaged memory.
Marshal.FreeHGlobal(hGlobal)
Console.WriteLine("Unmanaged memory was disposed.")
End Sub
End Module
