You can follow my code which is working fine.
What is the need of this code inside class student,
if(s1=="y"){...}
else if(s1=="n"{...}
else{...}
This code is absolutely not required. You are manipulating something here and due to that reason value is not coming.
You can simply put debugger in each line and you can check which value is going where.
Thanks.

hello salman and thanks for respond:
as you see in my program, in main mehtod, i read a string from console and put it in index, which puts in s1.. and i check if the string is correct, if so, it checks the value of s1 in my student class and do somthing there, but s1 in class student is empty??!! why...
i suppose that, because s1 is a public string in class student, it is stil empty after a method in class student implements....
i dont understand what is wrong?

class Student{
public string s1;
public string index
{
get{return this.s1;}
set{ this.s1 = value; }
}
if(s1=="y"){...}
else if(s1=="n"{...}
else{...}

static void Main(string[] args)
{
Student st = new Student();
Console.WriteLine("please choose y or n");
st.index = Console.ReadLine();
if (st.s1 == "y"||st.s1=="n"){here i go to class student to do something, but s1 is empty...why????}
else {Console.WriteLine("false string....");}

Hey. This code is working perfectly for me,
using System;

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            Student st = new Student();
            Console.WriteLine("please choose y or n");
            st.index = Console.ReadLine();
            if (st.s1 == "y")
            {
                Console.WriteLine("You Selected = " + st.s1);
            }
            else if (st.s1 == "n")
            {
                Console.WriteLine("You Selected = " + st.s1);
            }
            else
            {
                Console.WriteLine("You Selected Wrong Value");
            }
            Console.ReadLine();
        }
    }

    class Student
    {
        public string s1;
        public string index
        {
            get { return this.s1; }
            set { this.s1 = value; }
        }
    }
}
Output:-

If it helps Mark as answer.
