在 c# 中旋转的 Windows 窗体 [英] Windows forms spinning in c#

问题描述

我有两个窗体.现在我必须关闭第一个窗体并显示第二个窗体，反之亦然.我该怎么做.我将此指针传递给第二个窗体的构造函数，然后尝试关闭它，但这不起作用.我不能在这里使用 showdialog.

I have two windows forms.Now I have to close first one and show the second form and vice-versa.How can i do it.I was passing this pointer to the constructor of second form and then trying to close it,but this did not work.I can not use showdialog here.

推荐答案

为 Program 类中的每个表单添加静态变量:

Add static variables to each form in the Program class:

static class Program
{
    public static Form1 f1=null;
    public static Form2 f2 = null;

    public static FullClose=false;

    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);

        f1=new Form1();
        f2 = new Form2();

        Application.Run(f1);
    }
}

然后在每个表单的 Form_Closing 事件中:

Then in the Form_Closing event of each form:

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    if (Program.FullClose==false)
    {
       e.Cancel = true;
       this.Visible = false;

       Program.f2.Show();
    }
}

(在 Form2 中将 Program.f2.Show() 更改为 Program.f1.Show()).

(Change Program.f2.Show() to Program.f1.Show() in Form2).

当然，这会阻止应用程序关闭，因此您应该提供一个额外的按钮(或类似按钮)来设置一个布尔静态变量 (FullClose)，Form_Closing 事件可以检查它们是否应该正确关闭.

Of course this will stop the application from ever closing, so you should provide an extra button (or similar) that sets a boolean static variable (FullClose) that the Form_Closing events can check to see if they should properly close or not.
