直接上代码：
using System;
using System.Collections.Generic;
using System.Text;
namespace DynamicDemo
{
class Program
{
static void Main(string[] args)
{
dynamic dyn;
object obj;
dyn = 2;
obj = 3;
Console.WriteLine(dyn.GetType());
Console.WriteLine(obj.GetType());
dynamic output=Result(count:14,name:"hell");
Console.WriteLine(output);
output = Result(count: "NNN", name: "kaokaokao");
Console.WriteLine(output);
Console.ReadKey();
}static dynamic Result(dynamic count, string name = "fang wei")
{
string str = "hello word";
int y = 4;
if (count is int)
{
return count + y;
}
else
{
return str + name;
}}
}
}
