How to delete a file after checking whether it exists

by

This is pretty straightforward using the File class.

if(File.Exists(@"C:\test.txt"))
{
    File.Delete(@"C:\test.txt");
}

As Chris pointed out in the comments, you don’t actually need to do the File.Exists check since File.Delete doesn’t throw an exception if the file doesn’t exist, although if you’re using absolute paths you will need the check to make sure the entire file path is valid.
