What is the best way to add text to the beginning of a file using C#?

I couldn't find a straightforward way to do this, but came up with a couple work-arounds.

  1. Open up new file, write the text that I wanted to add, append the text from the old file to the end of the new file.

  2. Since the text I want to add should be less than 200 characters, I was thinking that I could add white space characters to the beginning of the file, and then overwrite the white space with the text I wanted to add.

Has anyone else come across this problem, and if so, what did you do?

Put the file's contents in a string. Append new data you want to add to the top of the file to that string -- string = newdata + string. Then move the seek position of the file to 0 and write the string into the file.
