 the SystemParameters, “type or namespace does not exist” 解决方法

* add a project reference

  • In Solution Explorer, expand the project, right click on References and click Add Reference.
  • Now click Browse on the bottom, find the DLL you are trying to use. In this case it should be included under Assemblies - Framework. Click on Framework on the left menu.
  • Find PresentationFramework on the right. Make sure you Check mark it
  • Click OK.

Now you have the reference, go back to your code and it should work. Again, make sure you create a WPF Project not WinForms...

using System.Windows.Forms in your code.

其他:

WinForm

   //获取PC屏幕的宽
        int width = Screen.PrimaryScreen.Bounds.Width;
  //获取PC屏幕的高
        int height = Screen.PrimaryScreen.Bounds.Height;

Screen.PrimaryScreen.WorkingArea.Height;

Screen.PrimaryScreen.WorkingArea.Width;

 

WPF

SystemParameters.WorkArea;//除任务栏外工作区大小
SystemParameters.PrimaryScreenWidth;//屏幕宽
SystemParameters.PrimaryScreenHeight;//屏幕高

double dWidth2 = ActualWidth; //获取此元素的呈现宽度。若此元素时全屏的,则可以获得屏幕大小

double dHeight2 = ActualHeight; //获取此元素的呈现高度。
