System IO File WriteAllText    D  path txt   contents      If the file exists  this overwrites it  If the file does not exist  this creates it   Please make sure you have appropriate privileges to write at the location  otherwise you will get an exception

If your code doesn t require the file to be truncated first  you can use the FileMode OpenOrCreate to open the filestream  which will create the file if it doesn t exist or open it if it does   You can use the stream to point at the front and start overwriting the existing file   I m assuming your using a streams here  there are other ways to write a file

Use the File WriteAllText method  It creates the file if it doesn t exist and overwrites it if it exists
