string converted = data.OfUploadsName.Replace(''-'', ''+'');
            converted = converted.Replace(''_'', ''/'');
            string[] spilt=converted.Split('','');
            byte[] bytes = Convert.FromBase64String(spilt[1]);
            Image image;
            using (MemoryStream ms = new MemoryStream(bytes))
            {
                image = Image.FromStream(ms);
            }
            //0.5
            var newWidth = (int)(image.Width * 1);
            var newHeight = (int)(image.Height * 1);
            var thumbnailImg = new Bitmap(newWidth, newHeight);
            var thumbGraph = Graphics.FromImage(thumbnailImg);
            thumbGraph.CompositingQuality = CompositingQuality.HighQuality;
            thumbGraph.SmoothingMode = SmoothingMode.HighQuality;
            thumbGraph.InterpolationMode = InterpolationMode.HighQualityBicubic;
            var imageRectangle = new Rectangle(0, 0, newWidth, newHeight);
            thumbGraph.DrawImage(image, imageRectangle);

            thumbnailImg.Save(HttpContext.Current.Server.MapPath(@"\SurveryDAL\Images\" + "''" + id + "''+.jpg"));

推荐答案

要尝试的四件事:
1)将路径更改为相对于您的站点的路径:

Four things to try:
1) Change the path to one relative to your site:

thumbnailImg.Save(HttpContext.Current.Server.MapPath(@"\SurveryDAL\Images\" + "''" + id + "''+.jpg"));

成为:

thumbnailImg.Save(HttpContext.Current.Server.MapPath(@"~\SurveryDAL\Images\" + "''" + id + "''+.jpg"));

2)删除文件名周围的引号，这些引号不是必需的，尽管它们在Windows下是合法的，但并非在所有系统上都可以.我不知道您的托管服务运行什么系统，但是最好尽可能保留字母数字文件名.
3)检查您正在生成的实际名称-将其记录下来或与调试器进行检查-准确找出要尝试写入的名称:并认真仔细检查该路径是否正确以及该文件尚不存在.由于您未在该代码中设置ID，因此可以是任何内容！
4)添加一个try ... catch块并记录并显示错误，以便您有更好的信息进行工作.

2) Remove the quotes around the filename, they aren''t needed, and while they are legal under Windows, they aren''t under all systems. I don;t know what system your hosting service runs, but it''s best to keep to alphanumerical files names where possible.
3) Check the actual name you are generating - log it or check with the debugger - to find out exactly what name you are trying to write to: and check really carefully that the path is fine and the file doesn''t exist already. Since you don''t set the id in that code, it could be anything!
4) Add a try...catch block and log and display the error so that you have better info to work on.
