什么是“冗余委托创建”?

我在班上注册了一个活动,和往常一样,我很懒,只使用Visual Studio 2008 Pro内置的自动完成功能,该功能自动创建委托创建及其相关方法。

public abstract class FooBase
{
    protected event EventHandler<MyValueChangedArgs> MyValueChanged;

    protected FooBase()
    {
        MyValueChanged +=
            new EventHandler<MyValueChangedArgs>(HandleMyValueChanged);
    }

    private void HandleMyValueChanged(object sender, MyValueChangedArgs e)
    {
        // Some handling logic
    }
}

public abstract class FooBase
{
    protected event EventHandler<MyValueChangedArgs> MyValueChanged;

    protected FooBase()
    {
        MyValueChanged += HandleMyValueChanged;
    }

    private void HandleMyValueChanged(object sender, MyValueChangedArgs e)
    {
        // Some handling logic
    }
}

谢谢。
