Do while loop in C# [SOLVED]

[mattykins]

I ask you guys way too many noob questions haha i'm sorry.

So i'm writing a do while loop as a test and my code thus far looks like this:

Code: Select all

           do
            {
                string userinput;
                userinput = Convert.ToString(Console.ReadLine());
            }
            while (userinput != "escape");

And I get the error 'userinput' does not exist in the current context.

Is it because i declared userinput inside of the loop?

Thanks in advanced

I've been learning java and not C# lol but I think its because userinput is considered a local variable, for you to be able to use it in the while statement you'd have to make it a class variable or something I hope that helps!

Thanks! But how would i go about doing that?

Code: Select all

do
            {
                string userinput;
                userinput = Convert.ToString(Console.ReadLine());
                return userinput;
            }
            while (userinput != "escape");

I think this is how you do it! Hopefully it's something like java. All this does is return the local variable to the class.

I'll try that right now Thanks. I'm still pretty noob here heh.

Good luck! I am too.

Sorry for double post! But its giving me the same error even with return userinput;

Well this is the point were I hand it off to the more experienced devs.

You can't return a variable from a FOR loop. Only from methods. Set it up like this:

Code: Select all

   string userinput = "";
   do
   {                
       userinput = Convert.ToString(Console.ReadLine());
   }
   while (userinput != "escape");

That way the userinput variable will be available both inside and outside of the DO-WHILE loop.
