重新启动 C# 应用程序而不实际关闭和重新打开? [英] Restart C# application without actually closing and re-opening?

问题描述

如何让我的所有内部代码像使用 Application.Restart() 一样工作，但实际上不必关闭并重新打开程序?

How can i get all of my internal code to work as if I used Application.Restart(), but without actually having the program have to close and reopen?

推荐答案

根据应用程序的设计，它可以像启动主窗体的新实例并关闭任何现有窗体实例一样简单.表单变量之外的任何应用程序状态也需要重置.对于听起来像您正在搜索的应用程序，没有神奇的重置"按钮.

Depending on the design of your application it could be as simple as starting a new instance of your main form and closing any existing form instances. Any application state outside of form variables would need to be reset as well. There's not a magic "reset" button for applications like it sounds like you're searching for.

一种方法是向 Program.cs 添加一个循环，以在表单在重置"后关闭时保持应用程序运行:

One way would be to add a loop to Program.cs to keep the app running if the form closes after a "reset":

static class Program
{
    public static bool KeepRunning { get; set; }

    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        KeepRunning = true;
        while(KeepRunning)
        {
            KeepRunning = false;
            Application.Run(new Form1());
        }
    }
}

并在您的表单(或工具栏等)中将 KeepRunning 变量设置为 true:

and in your form (or toolbar, etc.) set the KeepRunning variable to true:

private void btnClose_Click(object sender, EventArgs e)
{
    // close the form and let the app die
    this.Close();
}

private void btnReset_Click(object sender, EventArgs e)
{
    // close the form but keep the app running
    Program.KeepRunning = true;
    this.Close();
}
