复制代码，图片的截图 还有放大功能代码，分享主人的结晶

js代码 来自http://topic.csdn.net/u/20110314/11/9f3b0ada-abe5-4840-9df2-87b941b24ebe.html?seed=319809035&r=72241508#r_72241508

//截图代码
//获得当前屏幕的分辨率
var scr = Screen.PrimaryScreen;
var iWidth = scr.Bounds.Width;
var iHeight = scr.Bounds.Height;
//创建一个和屏幕一样大的
Bitmap var myImage = new System.Drawing.Bitmap(iWidth*1, iHeight*1);
var g3 = System.Drawing.Graphics.FromImage(myImage);
var br = new Rectangle(0,0,iWidth,iHeight);
g3.CopyFromScreen(0,0,0,0,br.Size);

myImage.Save(ph)
g3.Dispose()
myImage.Dispose()

图片放大代码

string strFileNameNew = "f://ddd2.png";
int w3, h3, iz; Color myColor;

Graphics g = Graphics.FromImage(bmpNew);
