namespace OverridDemo2
{
    class Program
    {
        static void Main(string[] args)
        {
            (new Program()).run();
        }
        void run()
        {
            int arg1 = 10;
            float arg2 = 12.5f;
            int arg3 = 30;
            DoWorkWithData();
            DoWorkWithData(arg1);
            DoWorkWithData(arg1, arg2);

            DoWorkWithData(intData:arg1, moreIntData:arg3);//指定传递给哪个参数.
            DoWorkWithData(floatData:arg2,moreIntData:arg3); //指定传递给哪个参数.
            DoWorkWithData(arg1, arg2,arg3);
        }
        void DoWorkWithData(int intData=0, float floatData=0.0f, int moreIntData=0)
        {
            Console.WriteLine("intData:{0},floatData:{1},moreIntData:{2}",
                intData, floatData, moreIntData);
        }

    }
}

注：在参数列表中，如果存在有默认值的和无默认值的情形，无默认值的参数必须在有默认值的参数前面.

eg: void DoWorkWithData(int intData, float floatData=0.0f, int moreIntData=0)
        {
            Console.WriteLine("intData:{0},floatData:{1},moreIntData:{2}",
                intData, floatData, moreIntData);
        }
