Question

asp.net网站：GDI+ 中发生一般性错误。

本人在开发asp.net网站，有一个上传图片的功能，并用代码实现将用户上传的图片加上本网站的logo（就是图片加水印）。以下是代码：if (FileUpload1.PostedFile.FileName.Trim() != ""){//上传文件string extension = Path.GetExtension(FileUpload1.PostedFile.FileName).ToUpper();string fileName = DateTime.Now.ToString("yyyyMMddhhmmss");string path = Server.MapPath(".") + "/ImageUpload/" + fileName + extension;FileUpload1.PostedFile.SaveAs(path); //加图片水印System.Drawing.Image image = System.Drawing.Image.FromFile(path);System.Drawing.Image copyImage = System.Drawing.Image.FromFile(Server.MapPath(".") + @"\ImageUpload\a.gif");Graphics g = Graphics.FromImage(image);g.DrawImage(copyImage, new Rectangle(image.Width - copyImage.Width, image.Height - copyImage.Height, copyImage.Width, copyImage.Height), 0, 0, copyImage.Width, copyImage.Height, GraphicsUnit.Pixel);g.Dispose();//保存加水印过后的图片,删除原始图片 string newPath = Server.MapPath(".") + "/UploadFile/" + fileName + "_new" + extension;image.Save(newPath);image.Dispose();if (File.Exists(path)){File.Delete(path);}Response.Redirect(newPath);}可是在运行时却报错“GDI+ 中
