I am really new to programming so please bear with me if my question sounds really stupid. I am trying to use the boolean to decide as in the following part:

 c# Syntax (Toggle Plain Text) 
                        bool B;
			string sString;
			Console.WriteLine ("Do you want to continue? Y/N");
			sString = Console.ReadLine();
			if (B = (sString = "Y"))
			{
				Console.WriteLine ("What else do you want to do?");
				Console.Read();
			}
                        bool B;
			string sString;
			Console.WriteLine ("Do you want to continue? Y/N");
			sString = Console.ReadLine();
			if (B = (sString = "Y"))
			{
				Console.WriteLine ("What else do you want to do?");
				Console.Read();
			}

but whenever I am trying to compile the code, it says "cannot implicitly convert type 'string' to 'bool'. Where am I going wrong? How should I write the if... structure correctly. Please help.

You really don't need the boolean in that expression. Just if( sString == "Y"). But if you really do want to use the boolean then the correct thing is if( (B = (sStirng == "Y")) ). Notice that = is an assignment operator, while == is a logical operator.

Thanks Ancient Dragon. That works perfectly.
