for loops

Question

Instruction:

Input a string from the user. The program will check to ensure that the string
has a length in the range of 2 to 10 characters (inclusive). If the user entered an
incorrect string, error messages for each error will be displayed(example below)
specifying the type of error, and a loop will be used to input a new string.

must use a for loop to do this.

Output should be.

Stringy

Enter a string: a
Error, the string is too short.

Enter a string: 123456789abc
Error, the string is too long.

Enter a string: ok string
o
k

s
t
r
i
n
g

Press any key to exit:

For program, i know how to use it a foreach loop
but that in a for loop and i don't know how to put a limit range in a string.

My code is:
        static void Main(string[] args)
        {
            string sName;

            Console.Title = "Stringy";

            Console.WriteLine("{0, 40}", "Stringy");

            Console.Write("Enter a string: ");
            sName = Console.ReadLine();

            foreach (char cValue in sName)
            {
                Console.WriteLine(cValue);
            }

            Console.WriteLine("Press any key to exit");
            Console.ReadLine();
       }
