类继承接口的问题

[maroon]

代码如下:
using System;

interface IStorable
{
void Read();
void Write();
}

interface ITalk
{
void Talk();
void Read();
}

public class Document : IStorable, ITalk
{
// the document constructor
public Document(string s)
{
Console.WriteLine("Creating document with: {0}", s);

}

public virtual void Read()
{
Console.WriteLine("Implementing IStorable.Read");
}

public void Write()
{
Console.WriteLine("Implementing IStorable.Write");

}

void ITalk.Read()
{
Console.WriteLine("Implementing ITalk.Read");
}

public void Talk()
{
Console.WriteLine("Implementing ITalk.Talk");
}

}

public class Note : Document
{
public Note(string s):
base(s)
{
Console.WriteLine("Creating Note with: {0}", s);
}

public override void Read()
{
Console.WriteLine("Implementing Document.Read");
}

//在这里想重写Document类的ITalk.Read()
void ITalk.Read()
{
Console.WriteLine("Implementing Document.Read");
}
}

public class Tester
{

static void Main()
{
// create a document object
Document theDoc = new Document("Test Document");
IStorable isDoc = theDoc as IStorable;
if (isDoc != null)
{
isDoc.Read();
}

ITalk itDoc = theDoc as ITalk;
if (itDoc != null)
{
itDoc.Read();
}

theDoc.Read();
theDoc.Talk();

//--------------
Note n = new Note("N");
n.Read();
//--------------
Console.ReadLine();
}

}


不明白的地方在这,请指教,谢谢.

//在这里想重写Document类的ITalk.Read()
void ITalk.Read()
{
Console.WriteLine("Implementing Document.Read");
}

override void ITalk.Read()
{
Console.WriteLine("Implementing Document.Read");
}

这样写会出错.

override void ITalk.Read()
{
Console.WriteLine("Implementing Document.Read");
}


错误 1 修饰符“override”对该项无效 C:\Documents and Settings\nh\My Documents\Visual Studio 2005\Projects\ExplicitImplementation\ExplicitImplementation\Program.cs 67 19 ExplicitImplementation

override 对应 virtual修饰词，还有接口的集成规则和类的继承规则不太相同

1：可以在调用上这样做：(n as ITalk).Read();
2：对类Note进行改写：

public class Note : Document, ITalk
{
	public Note(string s)
		:
		base(s)
	{
		Console.WriteLine("Creating Note with: {0}", s);
	}

	public override void Read()
	{
		(this as ITalk).Read();
	}

	#region ITalk 成员

	//在这里想重写Document类的ITalk.Read() 
	void ITalk.Read()
	{
		Console.WriteLine("Implementing Document.Read");
	}

[chinaicm]

interface ITalk
{
void Talk();
void Read();
}

把Read() 换个命名 ReadByTalk()

基类存在两个同名方法,继承类无法重写这两个同名的方法.

谢谢楼上的朋友,特别是hbxtlhx ,你的方法可以实现了,不过只能这样写代码了吗?非要在Note中加上ITalk?
