ASP.NET Basics (part 2): Not My Type

ASP.NET Basics \(part 2\): Not My Type

Now that you know how ASP.NET works, get to grips with the basic variables types - characters, strings and numbers - and the operators that are commonly used with them. This segment also explains how to cast variables into different types, either implicitly or explicitly, and briefly discusses the C# functions related to data type conversion between strings and numbers.

Discuss this article in this thread. You can read the article here .

Variable names

Quote:
In C#, a variable name ... must begin with a letter, optionally followed by more letters and numbers. ... reserved keywords cannot be used as variable names.


According to the C# Language reference [URL], variable names may also start with an underscore, contain Unicode escape sequences, and the "@" character is allowed as a prefix to enable keywords to be used as identifiers.

Examples:
Code:
class @class
{
   public static void @static(bool @bool) {
      if (@bool)
         System.Console.WriteLine("true");
      else
         System.Console.WriteLine("false");
   }   
}
class Class1
{
   static void M() {
      cl\u0061ss.st\u0061tic(true);
   }
}

   static void M() {
      cl\u0061ss.st\u0061tic(true);
   }
}


However, it is probably a good practice not to use unusual characters in variable names, as it may cause problems when you port your C# code elsewhere.
