image.save方法未保存图像GDI +错误发生 [英] image.save method is not save image GDI+ error occured

问题描述

 string ServerUploadFolder = HttpContext.Current.Server.MapPath("~/Uploads/" + value.PhysicalFileName);
                MultipartFormDataStreamProvider streamProvider = new MultipartFormDataStreamProvider(ServerUploadFolder);
                Image img = Image.FromFile(ServerUploadFolder);
                var bmp = new Bitmap(img.Width, img.Height);
 using (Graphics gfx = Graphics.FromImage(bmp))
                {
                    gfx.Clear(Color.White);
                    gfx.DrawImage(img, 0, 0, img.Width, img.Height);
                }
                bmp.RotateFlip(RotateFlipType.Rotate90FlipNone);
 string imagePath = value.FileUrl.Replace(Path.GetFileName(value.FileUrl), Path.GetFileName(value.FileUrl));
                bmp.Save(imagePath,img.RawFormat);

在此保存方法中存在问题发生的GDI +错误。
我尝试了很多解决方案但是没有用。
我是90度旋转图像，旋转后保存在数据库中。

In this Save Method There are Problem Occured GDI+ Error . I Have Tried Many Solutions but that is not worked. I am rotate image with 90's degree and after it is rotate it is save in database.

推荐答案

在五种情况下图像文件已经存在于系统驱动器中，因此应用程序会抛出错误GDI +中出现一般错误。

In may case the image file already exists in system drive, so app throws the error "A Generic error occured in GDI+".

1. 确认该文件夹必须已存在，才能保存图像。


2. 确认该文件必须不存在于同名路径中。
