The process cannot access the file ''D:\My Project\AzadUniv\New\12\GUI\Upload\NewsImage\5564868769930125853-Image'' because it is being used by another process.
==============================

string ImagePath = Server.MapPath(".")+"\\Upload\\NewsImage\\" + Utility.GenerateGUID() + "-Image";
            if (fuImage.PostedFile != null)
            {
                fuImage.PostedFile.SaveAs(ImagePath);
                fuImage.Dispose();
                string d = Utility.GetThumbnailImage(ImagePath, 100, 100,true);

            }



  public static string GetThumbnailImage(string path,int x,int y,bool DeleteAfterSave)
        {

                // Create the in-memory bitmap where you will draw the image.
                Bitmap image = new Bitmap(x, y);
                Graphics g = Graphics.FromImage(image);

                // Load the file data.
                System.Drawing.Image thumbnail =
                System.Drawing.Image.FromFile(path);

                // Draw the thumbnail.
                g.DrawImage(thumbnail, 0, 0, x, y);

                // Render the image.
                string NewPath = path +"-small.jpg";
               image.Save(NewPath, ImageFormat.Jpeg);
                
                g.Dispose();
                image.Dispose();
                if (DeleteAfterSave == true)
                {
                    System.IO.File.Delete(path);
                }
                return path;
            }

推荐答案

您正试图删除在 thumbnail 对象中读取的文件.也许如果您丢弃了缩略图对象，则文件资源将被释放.

You are attempting to delete the file that was read in within the thumbnail object. Perhaps if you disposed of the thumbnail object, the file resource would be released.
