Delete Image when done using it

[ralphtrent]

Hi
I have a class that downloads an image from a URL and save is on the local computer. What I do is then display the image. Next I would like to delete the image. But I can not seem to do that. Here is my code.

//Download File
public SaveLogo(string ImageUrl, string ImageTitle)
		{
			_outputFile = @Environment.GetFolderPath(Environment.SpecialFolder.MyPictures) + "\\" + ImageTitle + ".jpg";
			try
			{
				StreamReader URL = new StreamReader(System.Net.WebRequest.Create(ImageUrl).GetResponse().GetResponseStream());
				Image.FromStream(URL.BaseStream).Save(_outputFile ,System.Drawing.Imaging.ImageFormat.Jpeg);
			}
			catch (Exception ex)
			{
				throw ex;
			}
		}
//Do other code
.
.
.
//Delete the file when member is called
public void DeleteImage(string FileName)
		{
			try
			{
				System.IO.File.Delete(FileName);
			}
			catch (Exception ex)
			{
				throw ex;
			}
		}

I think this code is holding a lock on the file and not releasing it, there for my delete code is not working. Any Idea's?

Thanks

Your locking problem is not in the code you provided. I assume you are using Image.FromFile to load the file into an Image type. Image.FromFile does not release the file after reading it.

I suggest you handle the filestream yourself.

using System.IO;
using System.Drawing;
...
FileStream f = new FileStream(_outputFile, FileMode.Open);
Image i = Image.FromStream(f);
pictureBox1.Image = i;
f.Close();


Happy Coding.

Could be you just need to call the .Dispose() method of the acquired Image.

Well Im doing this in a web and a windows app. The windows app is using Image.FromStream, but the web app, just sets the source of a image control to the image. That is where I am failing. I do not see a way to release the resources on the web control. How would I release on the web control?

Thanks,
