Question

linq リクエストがあります。選択する必要がitem.Titleあります。どうやってこれをしますか？

var list = (from item in answer.SubItems.OfType<TItemView>()
            where item.SubItems != null
            from ty in item.SubItems
            select ty as TDealRequestView
                into request
                select new
                {
                    itemTitle = item.Title,//item not visible 
                    Title = request.Title,

                }).ToList();

Answer 1

キーワードを使用できます：let

in order to initialize your value request.Title

let request = your treatment... (request is local variable of your query)

Answer 2

今は確認できませんが、試してください：

String title;

var list = (from item in answer.SubItems.OfType<TItemView>()
        where item.SubItems != null
        let title=item.title 
        ...

        //now use title

Answer 3

交換：

select ty as TDealRequestView
            into request

と：

let request = ty as TDealRequestView
