Project Euler Solution using C#: Problem 2: Even Fibonacci Numbers

Problem:

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:

1, 2, 3, 5, 8, 13, 21, 34, 55, 89, ...

By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.
My Solution:


      static void Main(string[] args)         {             int val1 = 1;             int val2 = 2;             Int64 evenTerms = 2;             while (val2 < 4000000)             {                 int temp = val1;                 val1 = val2;                 val2 = temp + val2;                 if (val2 % 2 == 0)                 {                     evenTerms += val2;                 }             }             Console.WriteLine(evenTerms);             Console.ReadLine();         }
Note: You can simplifies the coding :)
