如何调用基接口方法？ [英] How can I call base interface method?

问题描述

如何调用基本接口方法？


class ThirdPartyClass：IDisposable {//我无法修改此类

void IDisposable.Dispose（ ）{

Console.WriteLine（" ThirdPartyClass Dispose"）;

}

}


class MyClass：ThirdPartyClass，IDisposable {

void IDisposable.Dispose（）{

Console.WriteLine（" MyClass Dispose"）;

//base.IDisposable.Dispose（）; //我怎么能这样做!!!!

}

}

好​​问题 - 说实话，我不是*想*你可以......

}

通常当基类实现IDisposable时，它也会实现

a" protected virtual void Dispose（bool disposing）"实际完成了清理工作......（如果操作正确）。

和Dispose（）方法调用它。


尝试覆盖它如下：


class ThirdPartyClass：IDisposable

{//我无法修改此类

void IDisposable.Dispose（）

{

GC.SuppressFinalize（this）;

Dispose（false）;

}


protected virtual void Dispose（bool disposing）

{

Console.WriteLine（" ThirdPartyClass Dispose" ）;

}

}


class MyClass：ThirdPartyClass，IDisposable

{

protected override void Dispose（bool disposing）

{

//在这里清理

Console.WriteLine（" MyClass Dispose"）;

base.Dispose（disposing）;

}

}


如果它没有实现Dispose（bool处理）


那么你应该像你一样，只做：


class ThirdPartyClass：IDisposable

{//我不能修改这个类

void IDisposable.Dispose（）

{

Console.WriteLine（" ThirdPartyClass Dispose" ）;

}

}


class MyClass：ThirdPartyClass，IDisposable

{

void IDisposable.Dispose（）

{

Console.WriteLine（" MyClass Dispose"）;

base.Dispose （）; //只需调用

Dispose的基类实现。

}

}

{

//在这里清理

控制台。 WriteLine（MyClass Dispose）;

base.Dispose（disposing）;

}

}

如果它没有实现Dispose（bool处理）并且它实现了

IDisposable as：void IDisposable.Dispose（），然后我猜你是

搞砸...... :(

How can I call a base interface method?

class ThirdPartyClass :IDisposable { //I can not modify this class
void IDisposable.Dispose() {
Console.WriteLine( "ThirdPartyClass Dispose" );
}
}

class MyClass :ThirdPartyClass, IDisposable {
void IDisposable.Dispose() {
Console.WriteLine( "MyClass Dispose" );
//base.IDisposable.Dispose(); //How can I do this !!!!
}
}

Good question - and to be honest, I don''t *think* you can...

Hi,

Usually when a base class implements an IDisposable, it also implements
a "protected virtual void Dispose(bool disposing)" where the acctually
cleanup is done... (if it is done correctly).
and the Dispose() method calls it.

try to override it as follow:

class ThirdPartyClass :IDisposable
{ //I can not modify this class
void IDisposable.Dispose()
{
GC.SuppressFinalize(this);
Dispose(false);
}

protected virtual void Dispose(bool disposing)
{
Console.WriteLine( "ThirdPartyClass Dispose" );
}
}

class MyClass :ThirdPartyClass, IDisposable
{
protected override void Dispose(bool disposing)
{
// Do your cleanup here
Console.WriteLine( "MyClass Dispose" );
base.Dispose(disposing);
}
}

if it doesn''t implement a Dispose(bool disposing)

then you should do as you did, only:

class ThirdPartyClass :IDisposable
{ //I can not modify this class
void IDisposable.Dispose()
{
Console.WriteLine( "ThirdPartyClass Dispose" );
}
}

class MyClass :ThirdPartyClass, IDisposable
{
void IDisposable.Dispose()
{
Console.WriteLine( "MyClass Dispose" );
base.Dispose(); // just call the base class implementation of the
Dispose.
}
}

Cheers,
Eyal.

screwed... :(
