原理比较简单，引入System.Reflection命名空间，利用反射查看某种Type下的方法，属性，字段和支持的接口等。
namespace ConsoleApplication1

class Program

static void Main(string[] args)

while (true)
{
Console.WriteLine("Please input a type:");
string typeStr = Console.ReadLine();
if (typeStr == "exit" || typeStr == "quit")
break;
try
{
Type type = Type.GetType(typeStr);
ListFields(type);
ListMethods(type);
ListInterfaces(type);
}
catch (Exception ex)
{
Console.WriteLine("It is not a valid type!");
}
}
}
#region Methods
