示例1: Main
//引入命名空间
using System;
using System.Runtime.InteropServices;
public struct Point
{
public int x;
public int y;
}
class Example
{
static void Main()
{
// Create a point struct.
Point p;
p.x = 1;
p.y = 1;
Console.WriteLine("The value of first point is " + p.x + " and " + p.y + ".");
// Initialize unmanged memory to hold the struct.
IntPtr pnt = Marshal.AllocHGlobal(Marshal.SizeOf(p));
try
{
// Copy the struct to unmanaged memory.
Marshal.StructureToPtr(p, pnt, false);
// Create another point.
Point anotherP;
// Set this Point to the value of the
// Point in unmanaged memory.
anotherP = (Point)Marshal.PtrToStructure(pnt, typeof(Point));
Console.WriteLine("The value of new point is " + anotherP.x + " and " + anotherP.y + ".");
}
finally
{
// Free the unmanaged memory.
Marshal.FreeHGlobal(pnt);
}
}
}示例2: Point
// Demonstrate the use of the SizeOf method of the Marshal class.
Console.WriteLine("Number of bytes needed by a Point object: {0}",
Marshal.SizeOf(typeof(Point)));
Point p = new Point();
Console.WriteLine("Number of bytes needed by a Point object: {0}",
Marshal.SizeOf(p));
