启动新窗口时如何关闭当前窗口(在代码中) [英] How to close current window (in Code) when launching new Window
问题描述
SignInWindow signIn= new SignInWindow();
signIn.ShowDialog();
以上代码在我的 MainWindow 类中.
The above code is in my MainWindow class.
当显示新窗口时,我希望关闭当前窗口.最好的方法是什么?
When the new Window is shown, I want the current window to close. Whats the best way to do this?
我的应用程序是一个 C# WPF 应用程序
My application is a C# WPF application
我已经尝试过这个,但是当它被调用时,我的应用程序退出
I've tries this but when it's called, my application exits
static private void CloseAllWindows()
{
for (int intCounter = App.Current.Windows.Count - 1; intCounter >= 0; intCounter--)
App.Current.Windows[intCounter].Close();
}
推荐答案
只需这样做:
this.Close();
SignInWindow signIn = new SignInWindow();
signIn.ShowDialog();
请记住,这实际上会关闭MainWindow
.如果您真的只是想隐藏它,那么请执行以下操作:
bear in mind that will actually close the MainWindow
. If all you're really trying to do is hide it, then do this:
this.Hide();
SignInWindow signIn = new SignInWindow();
signIn.ShowDialog();
this.Show();
这将在登录表单启动时隐藏MainWindow
,但是当它完成时显示.
That will hide the MainWindow
while the login form is up, but then show it again when it's complete.
好的,显然您是从外部表单的静态类
启动此表单.那将是非常相关的信息.但解决方案是这样的:
Okay, so apparently you're launching this form from a static class
that is outside the form. That would have been pretty relevant information. But a solution would be this:
var w = Application.Current.Windows[0];
w.Hide();
SignInWindow signIn = new SignInWindow();
signIn.ShowDialog();
w.Show();
