C#获取屏幕的宽度和高度

//1、在屏幕的右下角显示窗体
//这个区域不包括任务栏的
Rectangle ScreenArea = System.Windows.Forms.Screen.GetWorkingArea(this);
//这个区域包括任务栏，就是屏幕显示的物理范围
Rectangle ScreenArea = System.Windows.Forms.Screen.GetBounds(this);
int width1 = ScreenArea.Width; //屏幕宽度 int height1 = ScreenArea.Height; //屏幕高度
this.Location = new System.Drawing.Point(width1 - 窗体宽度, height1 - 窗体高度); //指定窗体显示在右下角
//2、在母窗体的中间显示子窗体的位置计算
waitForm.Location = new Point((this.Location.X + (this.Width - waitForm.Width) / 2),
(this.Location.Y + (this.Height - waitForm.Height) / 2));Web下：System.Web.HttpBrowserCapabilities hbc=new System.Web.HttpBrowserCapabilities();

Demo

Rectangle ScreenArea = Screen.GetWorkingArea(this);
this.Size = new Size(100,ScreenArea.Height);//设置为屏幕高度
