示例1: Example
' 导入命名空间
Imports System.Runtime.InteropServices
Public Structure Point
Public x As Integer
Public y As Integer
End Structure
Module Example
Sub Main()
' Create a point struct.
Dim p As Point
p.x = 1
p.y = 1
Console.WriteLine("The value of first point is " + p.x.ToString + " and " + p.y.ToString + ".")
' Initialize unmanged memory to hold the struct.
Dim pnt As IntPtr = Marshal.AllocHGlobal(Marshal.SizeOf(p))
Try
' Copy the struct to unmanaged memory.
Marshal.StructureToPtr(p, pnt, False)
' Create another point.
Dim anotherP As Point
' Set this Point to the value of the
' Point in unmanaged memory.
anotherP = CType(Marshal.PtrToStructure(pnt, GetType(Point)), Point)
Console.WriteLine("The value of new point is " + anotherP.x.ToString + " and " + anotherP.y.ToString + ".")
Finally
' Free the unmanaged memory.
Marshal.FreeHGlobal(pnt)
End Try
End Sub
End Module
