Recommendations for using C #: writing "temporary" files for download: a place in the application environment folder or temp folder

Basically, I wonder if there is a best practice when it comes to the next problem of downloading files, not just for temporary use, but ultimately for moving them to the application folder. I came across some options:

//Option 1 - Random file String tempfile = Path.GetTempFileName(); WriteData(tempfile); File.Move(tempfile, Path.Combine(Environment.CurrentDirectory, filename); //Option 2 - Temp Path + Random file name String tempfile = Path.Combine(Path.GetTempPath(), Path.GetRandomFileName()); WriteData(tempfile); File.Move(tempfile, Path.Combine(Environment.CurrentDirectory, filename); //Option 3 - Temp Path + real file name String tempfile = Path.Combine(Path.GetTempPath(), filename); WriteData(tempfile); File.Move(tempfile, Path.Combine(Environment.CurrentDirectory, filename); //Option 4 - Temp Application Path + Random file name String tempfile = Path.Combine(Environment.CurrentDirectory, Settings.Default.DownloadFolder, Path.GetRandomFileName()); WriteData(tempfile); File.Move(tempfile, Path.Combine(Environment.CurrentDirectory, filename); //Optioin 5 - Temp Application Path + file name String tempfile = Path.Combine(Environment.CurrentDirectory, Settings.Default.DownloadFolder, filename); WriteData(tempfile); File.Move(tempfile, Path.Combine(Environment.CurrentDirectory, filename);

Since some files are used at the time, I have no way to write the file directly to where it ends. He must go to the time domain ...

Your first option is very nice. Its pretty clear and well-documented what is happening here.

 //Option 1 - Random file String tempfile = Path.GetTempFileName(); WriteData(tempfile); File.Move(tempfile, Path.Combine(Environment.CurrentDirectory, filename);

Except for the Environment.CurrentDirectory bit. Since Astander points to this answer , you probably want to use AppDomain.BaseDirectory, because dialogs can change the environment .CurrentDirectory

// Option 4 - Temp + Application Path Random File Name

 String tempfile = Path.Combine(Environment.CurrentDirectory, Settings.Default.DownloadFolder, Path.GetRandomFileName()); WriteData(tempfile); File.Move(tempfile, Path.Combine(Environment.CurrentDirectory, filename);

This is the best choice because it will not raise SecurityExceptions or IOException, others may

Are these winforms? The web? WPF? what? Why not just save it in the user profile of the application?
