C# Basics: Bonus exercises (Averager)

Question

I am trying to build one of the 'bonus projects' for C# Basics... I am brand new to the language and I can't understand why this won't compile.

The program is intended to take numbers from the user, and average them.

using System;

namespace Treehouse.ExtraProjects
{
    class Program
    {
        static void Main()

        {
          int a = 0;

          while(true){

            Console.Write("Enter numbers to be averaged... type 'quit' when you want a total: ");

            var input = Console.ReadLine();

            if (input.ToLower = "quit")

              {
              break;
              }

            else

              try
              {
                var b += Double.Parse(input);
                a += 1;
                continue;
              }

              catch(FormatException)
              {
              Console.WriteLine("That is not valid input.");
              continue;
              }



            }

          Console.WriteLine(b / a);
          }
        }
    }

I am getting error messages regarding the "+=" with variable b, as well an error message regarding the "else-try" statement.

I know this is probably an obvious mistake, but any help you guys could give me would be much appreciated.

Thanks in advance!

EDIT:

I have caught one of my mistakes, and declared

var b = 0.0;

at the top of my code.. but I am still getting:

averager.cs(20,23): error CS0131: The left-hand side of an assignment must be a variable, a property or an indexer

... and I don't know how to fix it. This is error is in regards to:

if (input.ToLower = "quit")

There are a couple of errors in the below conditional check:

if (input.ToLower = "quit")

After "input.ToLower", function call operator "()" is missing.
You should use "Equals" method rather than '=' to check for string equality.

Therefore, the corrected conditional check should be:

if (input.ToLower().Equals("quit"))
