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!

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
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++ });
