从列表中删除项目的正确方法是什么 <WeakReference<T> &gt;？

Question

Is the following loop approach, using TryGetTarget then compare the proper way?

void Remove<T>( List<WeakReference<T>> list, T toRemove ) where T : class {
    for(var i=0; i<list.Count; ++i) {
        if(list[i].TryGetTarget(out var el) && el==toRemove) {
            list.RemoveAt(i);
            break;
        }
    }
}

Is there a more elegant or suggested way to do this?

Answer 1

您可以将其缩短为：

list.RemoveAll(item => item.TryGetTarget(out var el) && el == toRemove);
