更改启动窗口 [英] Change Startup Window

问题描述

我正在使用Visual Studio 2012 C#.我已经创建了一个带有主窗口的WPF应用程序项目，并向我的项目添加了一个登录窗口.我想将启动窗口更改为我的登录窗口，但似乎无法这样做.

I am using Visual Studio 2012 C#. I have created a WPF application project with a main window and added a login window to my project. I want to change the startup window to be my login window but can't seem to do so.

我去了属性，但是我看到的只有Myproject.app-它不应该显示我的项目的形式吗?

I went to the properties but all I see there is Myproject.app - should it not display the forms of my project?

无论如何，我都尝试过通过代码运行窗口:

Anyway I have tried running the window from code as well like so :

Application.Run(new Login());

但这似乎不起作用.它给出一个错误说:

But that does not seem to work. It gives an error saying :

错误1非静态字段，方法或属性'System.Windows.Application.Run(System.Windows.Window)'需要对象引用

Error 1 An object reference is required for the non-static field, method, or property 'System.Windows.Application.Run(System.Windows.Window)'

推荐答案

要更改启动窗口，请通过更改 Application.StartupUri 来更新 App.xaml :

To change startup window update App.xaml by changing Application.StartupUri:

<Application ... StartupUri="MainWindow.xaml">
