Handling with temporary file stream

Question

Say I want to define a TempFileStream class that creates a temporary file using Path.GetTempFileName() method. A temporary file must be deleted when TempFileStream\'s object

Answer 1

Try this one instead:

public class TempFileStream : FileStream
{
    public TempFileStream()
        : base(Path.GetTempFileName(), FileMode.Create, FileAccess.ReadWrite, FileShare.Read, 4096, FileOptions.DeleteOnClose) { }
    public TempFileStream(FileAccess access)
        : base(Path.GetTempFileName(), FileMode.Create, access, FileShare.Read, 4096, FileOptions.DeleteOnClose) { }
    public TempFileStream(FileAccess access, FileShare share)
        : base(Path.GetTempFileName(), FileMode.Create, access, share, 4096, FileOptions.DeleteOnClose) { }
    public TempFileStream(FileAccess access, FileShare share, int bufferSize)
        : base(Path.GetTempFileName(), FileMode.Create, access, share, bufferSize, FileOptions.DeleteOnClose) { }
}

The FileOptions.DeleteOnClose option will ensure that the OS deletes the temporary file automatically when you close out the file. No need for a special Dispose method, because it's all taken care of for you.
