Can't reach if statement

Hello I am writing a program in C# that takes a number and asks the user for a number, once the user enters the number the program checks if it matches the original number, if not it is supposed to tell the user if their answer was less or greater than, however my if statement is not working.

   // Boolean if user passes
         Boolean Userpassed;
         // Declares Answer Variable
         int answer = 6;
         // Asks user for a number
         Console.WriteLine("Enter a number between 1 and 10");
         // Displays Message
         Console.ReadLine();
         // Takes User Input as String
         string useranswer = Console.ReadLine();
         // Declares integer for actual integer
         int userinput;
         // User string parsed to Int
         userinput =  Convert.ToInt32(Console.Read());
        // Displays Message
         Console.ReadLine();
        // Checks if input is equal to answer
        if (userinput == answer)
         {
             // User passes
             Console.WriteLine("Congratulations, you have passed");

         }
        // Checks if input is greater than answer
        else
             if (userinput > answer)
         {
             // User Fails
             Console.WriteLine("The actual answer is less than what you entered");
         }
        // Checks if input is less than answer
        else
             if (userinput < answer)
             {
             // User Fails
             Console.WriteLine("The actual answer is greater than what you entered");
             }
         // Displays Message
         Console.ReadLine();

The first if statement does not work as when I enter 6 it simply passes to the else loop. Then if I enter a different number it does not get past the second else loop. How do I fix this problem?
