一共有二种方法,也不知道作者从哪里复制来的,先感谢原作者。

首先建立一个程序,加2个按钮,为了区分,界面修改成红色。

第一种:

1.建立一个主程序,加一个panel1,为了区分背景是绿色

2.代码调用

3.所有代码

        }
    }
}

4.效果很好。红配绿,绝配。 

第二种

和第一种方式有点不一样。 

 1.建立一个winform主程序,为了区分背景是绿色

2.把代码直接复制进去,修改命名空间,再加上一个load事件即可

3.代码

        {

            try
            {
                // Put it into this form
                SetParent(app.MainWindowHandle, control.Handle);
            }
            catch (Exception ex1)

                Console.WriteLine(ex2.Message);
            }
            try
            {
                MoveWindow(app.MainWindowHandle, 0, 0, control.Width, control.Height, true);
            }
            catch (Exception ex3)
            {
                Console.WriteLine(ex3.Message);
            }
        }


        private void Form1_Load(object sender, EventArgs e)
        {

            //以下这段代码是通过命令行方式调起一个exe程序,获取这个程序的句柄然后嵌入主的winform窗体中
            ProcessStartInfo info = new ProcessStartInfo(AppDomain.CurrentDomain.BaseDirectory + "WindowsFormsApp4.exe");//debug下面的文件夹
            info.WindowStyle = ProcessWindowStyle.Minimized;
            info.UseShellExecute = false;
            info.CreateNoWindow = false;
            m_AppProcess = System.Diagnostics.Process.Start(info);
            Application.Idle += appIdleEvent;
            try
            {
                EmbedProcess(m_AppProcess, this);
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }

    }
}

4.效果

 

可见,第一种和第二种的效果有所区别的。

拓展。

WPF签入winform

1.依然用上面的winform程序,把输出类型改成类库

  

2.建立一个WPF程序,引用System.Windows.Forms和WindowsFormsIntegration,红色。绿色是步骤1生产的dll

 3.在wpf中增加WindowsFormsHost控件

4.cs后台代码

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
using WindowsFormsApp4;

namespace WpfApp1
{
    /// 
    /// MainWindow.xaml 的交互逻辑
    /// 
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            Form1 mainform = new Form1();
            mainform.TopLevel = false;
            winform.Child = mainform;
        }
    }
}

 5.效果
