我们能够利用匿名方法更新名单?
原标题:Can we update a list using anonymous methods?

我有一份物体清单(MyList),我谨更新该清单中每个项目的一件财产(Priority)。

下面的法典是否适用于这一点?

this.MyList.All(
    delegate(ItemViewModel itemObject)
    {   
        itemObject.Priority = priority++;
    }
)

请帮助我。 提前感谢!

最佳回答

Why not just use foreach?

foreach(ItemViewModel itemObject in MyList)
  itemObject.Priority = priority++;

如果你真想使用代表的话,可使用<>ForEach():

MyList.ForEach(itemObject =>
{
    itemObject.Priority = priority++;
});

这样做是不可取的,因为你对<代码>实行副作用。 附 件

问题回答

如果名单是一份,则请使用:

MyList.ForEach(i => i.Priority = priority++);

或等同:

MyList.ForEach(delegate(ItemViewModel i) { i.Priority = priority++ });
