这篇文章主要介绍了C#的winform如何嵌套另一个exe程序问题，具有很好的参考价值，希望对大家有所帮助。如有错误或未考虑完全的地方，望不吝赐教

C#winform嵌套另一个exe程序

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

            exetool.LoadEXE(panel1, AppDomain.CurrentDomain.BaseDirectory+ "WindowsFormsApp4.exe");//debug下面的文件夹
        }
    }
}

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

        {

            }
            if (m_AppProcess.MainWindowHandle == IntPtr.Zero) return;

            if (app == null || app.MainWindowHandle == IntPtr.Zero || control == null) return;
            try
            {
                // Put it into this form
                SetParent(app.MainWindowHandle, control.Handle);
            }
            catch (Exception ex1)
            {
                Console.WriteLine(ex1.Message);
            }
            try
            {
                // Remove border and whatnot               
                SetWindowLong(new HandleRef(this, app.MainWindowHandle), GWL_STYLE, WS_VISIBLE);
            }
            catch (Exception ex2)
            {
                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
{
    /// <summary>
    /// MainWindow.xaml 的交互逻辑
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            Form1 mainform = new Form1();
            mainform.TopLevel = false;
            winform.Child = mainform;
        }
    }
}

5.效果

总结

以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
