How to write a code as string variable (C#)

Question

I'm working on exam in which when the student asked to something like (declare if statement) he will answer in Rich text box.

the question is: I want to search for the input of the student in that box, and therefore, I must declare a string that contains the code (as string) something like that:

string check = "            string stat = "new";
            if (stat == "new")
            {
                Console.WriteLine(stat);
            }
";

However, the problem is that, the escape characters and the other preserved voids such as (if).

Briefly: I want to create string that contains a code.

NOTE: I have tried the @ and putting before escape characters, but it didn't work.

Thanks

This is called the escape sequence and looks like concatenated with " (or another symbol):

string check = " ... " ...";

Where " means "
