第一:新建一个类(Class)
Win32Native.cs
代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
namespace WpfApplication1
{
public class Win32Native
{
[System.Runtime.InteropServices.DllImport("user32.dll", EntryPoint = "SetParent")]
public extern static IntPtr SetParent(IntPtr childPtr, IntPtr parentPtr);
}
}
第二:新建两个窗体:
Window1.xaml
Window2.xaml
第三:Window1.xaml.cs中添加引用
using System.Windows.Interop;
第四:在Window1窗体中放上一个Button1
其事件如下:
private void button1_Click(object sender, RoutedEventArgs e)
{
Window2 w2 = new Window2();
w2.Show();
WindowInteropHelper parentHelper = new WindowInteropHelper(this);
WindowInteropHelper childHelper = new WindowInteropHelper(w2);
Win32Native.SetParent(childHelper.Handle, parentHelper.Handle);
testMdiWindow.WindowState = WindowState.Maximized;//加上这句可实现窗口加载时最大化,注意语句位置
}
WinForms实现方法较简单一些,
private void button1_Click(object sender, RoutedEventArgs e)
{
Window2 w2 = new Window2();
w2.MdiParent = this;
w2.Show();
