Clearing content of text file using C#

Question

How can I clear the content of a text file using C# ?

Solution 1

File.WriteAllText(path, String.Empty);

Alternatively,

File.Create(path).Close();

Solution 2

Just open the file with the FileMode.Truncate flag, then close it:

using (var fs = new FileStream(@"C:\path\to\file", FileMode.Truncate))
{
}

Solution 3

 using (FileStream fs = File.Create(path))
 {

 }

Will create or overwrite a file.

Solution 4

You can clear contents of a file just like writing contents in the file but replacing the texts with ""

File.WriteAllText(@"FilePath", "");

Solution 5

Another short version:

System.IO.File.WriteAllBytes(path, new byte[0]);

Wow, even shorter than mine! +1

Since there's no code in the block, the using statement offers no advantage over .Close().

I'm assuming he'd be doing something with the file.

what do you mean "shorter" than yours?
