Another short version:

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

Answer 2

You can use always stream writer.It will erase old data and append new one each time.

using (StreamWriter sw = new StreamWriter(filePath))
{                            
    getNumberOfControls(frm1,sw);
}

Answer 3

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

 }

Will create or overwrite a file.

Answer 4

File.WriteAllText(path, String.Empty);

Alternatively,

File.Create(path).Close();

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

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