Question

[C#] I need to convert this if/else statements into Switch

I have the code for the if/else but now need to turn it into a switch. The Console.WriteLine and all that is fine. I just need to convert the if/else.

     int x1, x2, y1, y2;
                Console.WriteLine("What is smallest value of x:");
                x1 = Convert.ToInt32(Console.ReadLine());
                Console.WriteLine("What is largest value of x:");
                x2 = Convert.ToInt32(Console.ReadLine());
                Console.WriteLine("What is smallest value of y:");
                y1 = Convert.ToInt32(Console.ReadLine());
                Console.WriteLine("What is largest value of y:");
                y2 = Convert.ToInt32(Console.ReadLine());
                Console.WriteLine("Enter the operator:");
                string op = Console.ReadLine();
                Console.WriteLine("How many times should it happen?:");
                int n = Convert.ToInt32(Console.ReadLine());
                Random random = new Random();
                for (int i = 1; i <= n; i++)
                {
                    int x = random.Next(x1, x2);
                    int y = random.Next(y1, y2);
                    Console.Write("What is the result of " + x + " " + op + " " + y + " = ");
                    int ans = Convert.ToInt32(Console.ReadLine());
                    int result = 0;
                    if (op == "+")
                    {
                        result = x + y;
                    }
                    else if (op == "-")
                    {
                        result = x - y;
                    }
                    else if (op == "*")
                    {
                        result = x * y;
                    }
                    else if (op == "%")
                    {
                        result = x % y;
                    }
                    else
                    {
                        result = x / y;
                    }
                    if (result == ans)
                    {
                        Console.WriteLine("Congratulations");
                    }
                    else
                    {
                        Console.WriteLine("Wrong answer. Correct answer is " + result);
                    }
                }

I have modified the code with switch statement

using System;

public class GFG{
   static public void Main (){
       //Code
       int x1, x2, y1, y2;
Console.WriteLine("What is smallest value of x:");
x1 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("What is largest value of x:");
x2 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("What is smallest value of y:");
y1 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("What is largest value of y:");
y2 = Convert.ToInt32(Console.ReadLine());
Console.WriteLine("Enter the operator:");
string op = Console.ReadLine();
Console.WriteLine("How many times should it happen?:");
int n = Convert.ToInt32(Console.ReadLine());
Random random = new Random();
for (int i = 1; i <= n; i++)
{
int x = random.Next(x1, x2);
int y = random.Next(y1, y2);
Console.Write("What is the result of " + x + " " + op + " " + y + " = ");
int ans = Convert.ToInt32(Console.ReadLine());
int result = 0;
switch(op)
{
case "+":
result = x + y;
break;
case "-":
result = x - y;
break;
case "*":
result = x * y;
break;
case "%":
result = x % y;
break;
case "/":
result = x / y;
break;
  
}
if (result == ans)
{
Console.WriteLine("Congratulations");
}
else
{
Console.WriteLine("Wrong answer. Correct answer is " + result);
}
}
   }
}
