Fixed string size in C#

Question

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

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.

Thank you very much for your concern.

Answer 1

You could declare and fill a fixed size char array, and then pass that to the String objects constructor to make the string from that.

var newString = new string(theCharArray);

Answer 2

You should create a property of type string that checks value.Length in the setter and truncates it or throws an exception.

Answer 3

You should use 'StringBuilder' for your issue.
