使用NGif创建动画GIF后无法删除jpg文件(Unable to delete jpg files after creating animated GIF using NGif)

我已编程使用NGif从一些jog文件创建动画GIF文件。正在创建动画文件（只是自动幻灯片放映）没有任何问题。 GIF的源图像（我创建动画的jpg文件）位于“Temp2”文件夹中。我想删除包含文件的文件夹，但程序无法处理并给出消息：“...文件仍在被另一个进程使用”。

我创建的功能如下：

public void Create_Animated_GIF() { String Output_File_Path = Environment.CurrentDirectory + "\\Animation.gif"; AnimatedGifEncoder GEncoder = new AnimatedGifEncoder(); GEncoder.Start(Output_File_Path); GEncoder.SetDelay(100); GEncoder.SetRepeat(0); for (int i = 0; i < 2; i++) { GEncoder.AddFrame(System.Drawing.Image.FromFile(Image_URLs[i])); } /* try { System.IO.Directory.Delete(Environment.CurrentDirectory + "\\Temp2", true); } catch { } */ GEncoder.Finish(); System.IO.Directory.Delete(Environment.CurrentDirectory + "\\Temp2", true); }

The function that I created is as below:

public void Create_Animated_GIF() { String Output_File_Path = Environment.CurrentDirectory + "\\Animation.gif"; AnimatedGifEncoder GEncoder = new AnimatedGifEncoder(); GEncoder.Start(Output_File_Path); GEncoder.SetDelay(100); GEncoder.SetRepeat(0); for (int i = 0; i < 2; i++) { GEncoder.AddFrame(System.Drawing.Image.FromFile(Image_URLs[i])); } /* try { System.IO.Directory.Delete(Environment.CurrentDirectory + "\\Temp2", true); } catch { } */ GEncoder.Finish(); System.IO.Directory.Delete(Environment.CurrentDirectory + "\\Temp2", true); }

Here, I tried try-catch; it did not work!

Another function wjere I used this Temp2 folder is as follows:

public void Crop_Images() { if (!System.IO.Directory.Exists(Environment.CurrentDirectory + "\\Temp2\\")) System.IO.Directory.CreateDirectory(Environment.CurrentDirectory + "\\Temp2\\"); for (int i = 0; i < 2; i++) { System.Drawing.Image Source_Image = System.Drawing.Image.FromFile(Environment.CurrentDirectory + "\\Temp\\" + i.ToString() + ".jpg"); System.Drawing.Bitmap Source_Image_Btmp = new System.Drawing.Bitmap(Source_Image); System.Drawing.Rectangle Destin_Rect = new System.Drawing.Rectangle(1327, 1330, 632, 491); System.Drawing.Image Destin_Image = Source_Image_Btmp.Clone(Destin_Rect, Source_Image_Btmp.PixelFormat); Image_URLs[i] = Environment.CurrentDirectory + "\\Temp2\\" + i.ToString() + ".jpg"; Destin_Image.Save(Image_URLs[i]); Source_Image.Dispose(); Source_Image_Btmp.Dispose(); Destin_Image.Dispose(); } /* try { System.IO.Directory.Delete(Environment.CurrentDirectory + "\\Temp", true); } catch { } */ System.IO.Directory.Delete(Environment.CurrentDirectory + "\\Temp", true); }

Here, Temp folder is deleted successfully.

I tried to call the delete command after calling the relevant function from main; but still it didn't work!

Can anybody please help me how I can detach the folder from the process that I have created?
