title: Fixed string size in C#
body: <p>The short question:
  Is it possible to create a fixed size string in C#?
  I know that in VB it's possible declaring something like this: str AS string * 20</p>
  
  <p>The long story:
  I need to read a binary file that contains a 20 byte field into a string. I read the content of the file into an object (class). I want to limit the strings in the object in the class definition.</p>
  
  <p>Thank you very much for your concern.</p>
