How does this class implement IDisposable if it doesn't have a Dispose method?

FtpWebResponse implements IDisposable, but it doesn't have a Dispose method. How is that possible?

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.

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

It's implemented in the base class WebResponse

void IDisposable.Dispose()
{
try
{
    this.Close();
    this.OnDispose();
}
catch
{
}
}
