Temporary file class for C#

Quite frequently I need to create a temporary file, do some processing on it, then delete it. In order to ensure the file gets deleted, I put the file deletion code in a try…finally, which got me thinking about writing a simple class that implements IDisposable to handle this scenario, allowing me to use using. It’s very simple, but here it is anyway.

  public class TemporaryFile : IDisposable
  {
    public TemporaryFile(string fileName)
    {
      this.fileName = fileName;
    }

    ~TemporaryFile()
    {
      DeleteFile();
    }

    public void Dispose()
    {
      DeleteFile();
      GC.SuppressFinalize(this);
    }

    private string fileName;
    public string FileName
    {
      get { return fileName;  }
    }

    private void DeleteFile()
    {
      if (File.Exists(fileName))
        File.Delete(fileName);
    }
  }
