WPF当另一个窗口调用函数时

Question

I'm trying to create a login window in my WPF application, which I'm about to finish:

Here's what I'm trying to do:

I have a main window, which creates the login window.

In the login window, when the user logs in, I want to send an event "LoginSuccess".

In the main window, which is listening to the login window' events, a function get called.

In fact, I'm trying to do something like that:

public App()
{
    Window LoginWindow = new ...();
    LoginWindow.LoginSucceed += LoginSucceed;
}

void LoginSucceed(object sender, EventArgs e)
{
    // ....
}

How can I do that?

Answer 1

You need to create a LoginSucceed event in your LoginWindow.xaml.cs class if you haven't already.

Create a class level variable that looks something like this:

public event RoutedEventHandler LoginSucceed;

After validating the user, you can trigger this event:

LoginSucceed(this, null)

You can then hook up to this event from your main window like you have above. Is that what your looking for?
