显式接口成员实现.txt

C# 是创新性的新式编程语言

ICloneable,IComparable,ICollection,IList,IDictionary

提供了更多的类型安全，并且还可以减少值类型的装箱操作。

using System;
namespace TestInFace
{
	
	
	struct SomeValueType:IComparable
	{
		private Int32 x;
		public SomeValueType(Int32 x){this.x=x;}
		//显示接口成员实现,带来类型上的这全
		public Int32 CompareTo(SomeValueType other)
		{
			return(x-other.x);
		}
		//满足接口合同
		Int32 IComparable.CompareTo(Object other)
		{
			return (x-((SomeValueType)other).x);
		}
		
	}
	class Class1
	{
		[STAThread]
		static void Main(string[] args)
		{
			//SomeValueType v=new SomeValueType(0);
			//Object o=new Object();
			//Int32 n=v.CompareTo(o);
			SomeValueType v1=new SomeValueType(0);
			SomeValueType v2=new SomeValueType(0);
			Int32 n=v1.CompareTo(v2);
			
		}
	}
