string strDotName=File1.PostedFile.FileName.Substring(File1.PostedFile.FileName.ToString().Length-4,4);
Random ro = new Random(System.DateTime.Now.GetHashCode());
string strFileName="image"+ro.Next()+strDotName;
File1.PostedFile.SaveAs(this.Server.MapPath("upload/"+strFileName));//图片上传结束，下面生成缩略图
System.Drawing.Image.GetThumbnailImageAbort myCallback =new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);
Bitmap myBitmap = new Bitmap(this.Server.MapPath("upload/")+"\\"+strFileName);
Bitmap tomap=new Bitmap(Server.MapPath("images/logo.gif"));
System.Drawing.Image myThumbnail = myBitmap.GetThumbnailImage(200,150,myCallback,IntPtr.Zero);
Response.ContentType="image/jpeg";
Bitmap newbmp=new Bitmap(myThumbnail);
Graphics g=Graphics.FromImage(newbmp);
g.DrawImageUnscaled(tomap,0,0,200,150); Random ro1 = new Random(System.DateTime.Now.GetHashCode());
string strName="image"+ro1.Next()+".jpg"; newbmp.Save(this.Server.MapPath("upload/"+strName),System.Drawing.Imaging.ImageFormat.Jpeg);
myBitmap.Dispose();
tomap.Dispose();
newbmp.Dispose();
