[RESOLVED] how to dynamically add a file name

[callydata]

So I am able to write to a .txt file, but I would like to have the file names change depending on the date when the process is run. How would I do this?
Here is my current code:

Dim oFile As System.IO.File
        Dim oWrite As System.IO.StreamWriter
        oWrite = oFile.CreateText("C:\New.txt")
        oWrite.WriteLine("This is working great.")
        oWrite.WriteLine()

Thanks
