FtpWebResponse implements IDisposable, but it doesn't have a Dispose method. How is that possible?
回答1:
It does have the Dispose method through inheritance, but it is an explicit implementation. To call it, you would have to use
((IDisposable)myObject).Dispose();
Or, of course, just wrap it in a using
block, as it does the explicit call for you.
回答2:
Its implemented in the base class WebResponse, see http://msdn.microsoft.com/en-us/library/system.net.webresponse_methods.aspx
回答3:
When you implement an interface
explicitly, you won't get the method in the listing. You will have to cast that object to implemented interface
to get access to that method.
public class MyClass : IDisposable
{
void IDisposable.Dispose()
{
throw new NotImplementedException();
}
}

It's implemented in the base class WebResponse
void IDisposable.Dispose()
{
try
{
this.Close();
this.OnDispose();
}
catch
{
}
}

It inherits from System.Net.WebResponse which implements these methods.
