[C#] Var 的使用與應用

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {
            // Example #1: var is optional because
            // the select clause specifies a string
            string[] words = { "apple", "strawberry", "grape", "peach", "banana" };
            var wordQuery = from word in words
                            where word[0] == 'p'
                            select word;

            // Because each element in the sequence is a string,
            // not an anonymous type, var is optional here also.
            foreach (string s in wordQuery)
            {
                Console.WriteLine(s);
            }

            Console.ReadLine();
        }
    }
}
