這篇文章主要介紹了C#的winform如何嵌套另一個(gè)exe程序問(wèn)題，具有很好的參考價(jià)值，希望對(duì)大家有所幫助。如有錯(cuò)誤或未考慮完全的地方，望不吝賜教

C#winform嵌套另一個(gè)exe程序

一共有二種方法，也不知道作者從哪里復(fù)制來(lái)的，先感謝原作者。

首先建立一個(gè)程序，加2個(gè)按鈕，為了區(qū)分，界面修改成紅色。

第一種

1.建立一個(gè)主程序，加一個(gè)panel1，為了區(qū)分背景是綠色

2.代碼調(diào)用

3.所有代碼

}

4.效果很好。

紅配綠，絕配。

第二種

和第一種方式有點(diǎn)不一樣。

1.建立一個(gè)winform主程序，為了區(qū)分背景是綠色

2.把代碼直接復(fù)制進(jìn)去，修改命名空間，再加上一個(gè)load事件即可

3.代碼

            }
        }
    }
}

4.效果

可見(jiàn)，第一種和第二種的效果有所區(qū)別的。

拓展。

WPF簽入winform

1.依然用上面的winform程序，把輸出類型改成類庫(kù)

2.建立一個(gè)WPF程序，引用System.Windows.Forms和WindowsFormsIntegration，紅色。綠色是步驟1生產(chǎn)的dll

3.在wpf中增加WindowsFormsHost控件

4.cs后臺(tái)代碼

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 WindowsFormsApp4;

{
    /// <summary>
    /// MainWindow.xaml 的交互邏輯
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            Form1 mainform = new Form1();
            mainform.TopLevel = false;
            winform.Child = mainform;
        }
    }
}

5.效果
