I am developing a C# console application using Visual Studio 2005.

I use the following statement in my program:
if (File.Exists(errorFilePath))

Is there a way to open this txt type file and see if this file is empty?
I want to delete this file, if it is an empty file.

Check the File.Lenth
if (File.Length==0)
                                Console.Writeline("File is empty.");

There is no File.Length method in the File class, but use FileInfo:
if (File.Exists(errorFilePath))
{
  if (new FileInfo(errorFilePath).Length == 0)
  {
          Console.WriteLine("{0} is empty", errorFilePath);
          File.Delete(errorFilePath);
   }
}
