如何让主窗口等待新打开的窗口在 C# WPF 中关闭? [英] How to make main window wait until a newly opened window closes in C# WPF?

问题描述

我是 WPF 和 C# 的新手，请耐心等待.

I am new to WPF as well as C#, please bear with me.

我有一个主窗口，可以打开一个新窗口.现在这个新窗口是提示是否覆盖文件，主窗口访问新窗口中的一个公共变量来检查提示结果.

I have a main window which opens up a new window. Now this new window is a prompt whether or not to overwrite a file, and the main window accesses a public variable in the new window to check for the prompt's result.

但是我无法让主窗口处理等到新窗口关闭.

But I can't get the main window processing to wait until the new window closes.

 Window1 Win = new Window1();
 Win.Show();

 if (Win.pr_res == 1)
 {
      abc.Text = "File to be overwritten";
      File.Delete(_destination);
      Start();
 }
 else
 {
      abc.Text = "Operation Aborted";
 }

我尝试在主窗口中添加一个 while 循环来检查另一个公共布尔值，但这只会挂起整个程序.

I tried adding a while loop checking another public boolean in the main window, but that just hangs the entire program.

 while(!_closecheck);

欢迎提出任何建议.

推荐答案

使用 ShowDialog 而不是 Show -

Win.ShowDialog();

来自 MSDN -

打开一个窗口，只有当新打开的窗口被打开时才返回关闭.

Opens a window and returns only when the newly opened window is closed.
