C# 委托中匿名方法的使用

匿名方法是用來創建委托實例的，下面來看一下具體的事例

namespace DeletateAndEvent
{
    //創建委托
    delegate int AddDelegate(int a,float b);
    delegate double AddDelegateD(float a,double b);
    class Program
    {
        static void Main(string[] args)
        {
            AddDelegate ad = delegate(int i, float f)//匿名方法
            { return i + (int)f; };
            int a = ad(20,12.5f);
            Console.WriteLine(a);

            AddDelegateD add = delegate(float f,double d)
            { return f * d; };
            double dd = add(10,20);
            Console.WriteLine(dd);

            ///下面這個方法就有點不理解了
            ad = delegate
            { return 12 + 12; };
            a = ad(0,0);
            Console.WriteLine(a);
        }
    }
}
