推荐答案

到目前为止，最简单的方法是创建表单的新实例并关闭旧实例。如果这是您应用程序的主要形式，则需要进行一些手术，关闭它会终止程序。首先打开Program.cs并对其进行编辑，使其看起来像这样：

By far the simplest way is to just create a new instance of the form and close the old one. That requires a little bit of surgery if this is the main form of your app, closing it would terminate the program. Start by opening Program.cs and edit it so it looks like this:

static class Program {
    [STAThread]
    static void Main() {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        AppContext = new ApplicationContext();
        AppContext.MainForm = new Form1();
        Application.Run(AppContext);
    }
    public static ApplicationContext AppContext;
}

ApplicationContext变量现在控制应用程序的生存期，而不是Form1实例。您可以在Form1中使用以下代码重新创建表单：

The ApplicationContext variable now controls the lifetime of the app, instead of the Form1 instance. You can recreate the form with code like this in Form1:

    private void button1_Click(object sender, EventArgs e) {
        Form1 frm = new Form1();
        frm.StartPosition = FormStartPosition.Manual;
        frm.Location = this.Location;
        frm.Size = this.Size;
        Program.AppContext.MainForm = frm;
        frm.Show();
        this.Close();
    }
