c# 窗口如何获取windows 分辨率大小

this.Width = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Width;
this.Height = System.Windows.Forms.Screen.PrimaryScreen.Bounds.Height;

Rectangle rect = new Rectangle();
rect = Screen.GetWorkingArea(this);
MessageBox.Show ( "本机器的分辨率是" + rect.Width.ToString ( ) + "*" + rect.Height.ToString ( ) ) ;

SystemInformation.VirtualScreen.Height.ToString()和SystemInformation.VirtualScreen.Width.ToString()。
其中SystemInformation这个类是提供当前系统环境的有关信息的类。
