示例1: MessageBox
//引入命名空间
using System;
using System.Runtime.InteropServices;
internal class Win32
{
// Use DllImportAttribute to inport the Win32 MessageBox
// function. Set the SetLastError flag to true to allow
// the function to set the Win32 error.
[DllImportAttribute("user32.dll", SetLastError = true, CharSet = CharSet.Unicode)]
public static extern int MessageBox(IntPtr hwnd, String text, String caption, uint type);
}
class Program
{
static void Run()
{
// Call the MessageBox with normal parameters.
Console.WriteLine("Calling Win32 MessageBox without error...");
Win32.MessageBox(new IntPtr(0), "Press OK...", "Press OK Dialog", 0);
// Get the last error and display it.
int error = Marshal.GetLastWin32Error();
Console.WriteLine("The last Win32 Error was: " + error);
// Call the MessageBox with an invalid window handle to
// produce a Win32 error.
Console.WriteLine("Calling Win32 MessageBox with error...");
Win32.MessageBox(new IntPtr(123132), "Press OK...", "Press OK Dialog", 0);
// Get the last error and display it.
error = Marshal.GetLastWin32Error();
Console.WriteLine("The last Win32 Error was: " + error);
