Question

这是我现在得到的错误

System.Runtime.InteropServices.ExternalException（0x80004005）：GDI +中发生一般错误。在System.Drawing.Image.Save（String filename，ImageCodecInfo encoder，EncoderParameters encoderParams）

我在同一台机器的其他网站上使用相同的代码并且没有问题我真的不知道发生了什么请给我解决方案

这是我的代码

double newHeight = 0;
        double newWidth = 0;
        double scale = 0;

        //create new image object
        Bitmap curImage = new Bitmap(filePath);

        //Determine image scaling
        if (curImage.Height > curImage.Width)
        {
            scale = Convert.ToSingle(size) / curImage.Height;
        }
        else
        {
            scale = Convert.ToSingle(size) / curImage.Width;
        }
        if (scale < 0 || scale > 1) { scale = 1; }

        //New image dimension
        newHeight = Math.Floor(Convert.ToSingle(curImage.Height) * scale);
        newWidth = Math.Floor(Convert.ToSingle(curImage.Width) * scale);

        //Create new object image
        Bitmap newImage = new Bitmap(curImage, Convert.ToInt32(newWidth), Convert.ToInt32(newHeight));
        Graphics imgDest = Graphics.FromImage(newImage);
        imgDest.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
        imgDest.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;
        imgDest.PixelOffsetMode = System.Drawing.Drawing2D.PixelOffsetMode.HighQuality;
        imgDest.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality;
        ImageCodecInfo[] info = ImageCodecInfo.GetImageEncoders();
        EncoderParameters param = new EncoderParameters(1);
        param.Param[0] = new EncoderParameter(System.Drawing.Imaging.Encoder.Quality, 100L);

        //Draw the object image
        imgDest.DrawImage(curImage, 0, 0, newImage.Width, newImage.Height);

        //Save image file
        newImage.Save(saveFilePath, info[1], param);

        //Dispose the image objects
        curImage.Dispose();
        newImage.Dispose();
        imgDest.Dispose();
    }

如果您运行的帐户无法保存到此行saveFilePath处的路径，则会收到GDI错误消息：

newImage.Save(saveFilePath, info[1], param);

尝试在Asp.net中保存文件时出错使用c＃
