How can I position the window's position on startup to the right side of the user's screen?
提问by anonymous
I am currently creating a sidebar-like WPF application in C#. When a user starts the application, I would like the window to automatically position it's self to the side of the user's screen. I have tried a few methods and google searches, but have not found any help.

I tried this code:
我试过这个代码：
private void Window_Loaded(object sender, RoutedEventArgs e)
{
this.Left = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Right - this.Width;
this.Top = 0;
this.Height = System.Windows.Forms.Screen.PrimaryScreen.WorkingArea.Height;
}
and got the following errors:
并得到以下错误：
Error 1 The type 'System.Drawing.Size' is defined in an assembly that is not referenced. You must add a reference to assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a'. C:\Users\Test\Documents\Expression\Blend 4\Projects\WindBar_Prototype_1\WindBar_Prototype_1\MainWindow.xaml.cs 32 13 WindBar_Prototype_1
错误 1 在未引用的程序集中定义了类型“System.Drawing.Size”。您必须添加对程序集“System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a”的引用。C:\Users\Test\Documents\Expression\Blend 4\Projects\WindBar_Prototype_1\WindBar_Prototype_1\MainWindow.xaml.cs 32 13 WindBar_Prototype_1
and
和
Error 2 'System.Drawing.Size' does not contain a definition for 'Width' and no extension method 'Width' accepting a first argument of type 'System.Drawing.Size' could be found (are you missing a using directive or an assembly reference?) C:\Users\Test\Documents\Expression\Blend 4\Projects\WindBar_Prototype_1\WindBar_Prototype_1\MainWindow.xaml.cs 32 78 WindBar_Prototype_1
错误 2“System.Drawing.Size”不包含“Width”的定义，并且找不到接受“System.Drawing.Size”类型的第一个参数的扩展方法“Width”（您是否缺少 using 指令或程序集参考？）C:\Users\Test\Documents\Expression\Blend 4\Projects\WindBar_Prototype_1\WindBar_Prototype_1\MainWindow.xaml.cs 32 78 WindBar_Prototype_1
Any help?
有什么帮助吗？

You can use Screenfrom System.Windows.Forms.
您可以使用Screen从System.Windows.Forms.
So add reference to the System.Windows.Forms.dlland System.Drawing.dll. Then change the Leftand Heightproperty in the MainWindow_Loadedmethod.
所以添加对System.Windows.Forms.dlland 的引用System.Drawing.dll。然后更改方法中的LeftandHeight属性MainWindow_Loaded。

public MainWindow()
{
InitializeComponent();
WindowStartupLocation = WindowStartupLocation.Manual;
Left = System.Windows.Forms.SystemInformation.PrimaryMonitorSize.Width - Width;
}

in your xaml :
在您的 xaml 中：
WindowStartupLocation="Manual"
in the constructor :
在构造函数中：
Left = System.Windows.SystemParameters.PrimaryScreenWidth - Width
Top=0
回答by KurToMe
You can do this without referencing win forms assemblies by using SystemParameters. In the code behind for your window XAML:
您可以使用SystemParameters. 在您的窗口 XAML 背后的代码中：
MainWindow() {
InitializeComponents();
this.Loaded += new RoutedEventHandler(
delegate(object sender, RoutedEventArgs args) {
Width = 300;
Left = SystemParameters.VirtualScreenLeft;
Height = SystemParameters.VirtualScreenHeight;
}
}
