LINQ的回报布尔其中a = VAL1＆安培;从模型B = val2的？ [英] Linq return bool where a = val1 & b = val2 from model?

问题描述

我有2个for循环，需要根据当前的人来检查，如果模型中包含的值。

I have 2 for loops and need to check if the model contains value based on current ones.

<% for (int currentDay = 1; currentDay <= 7; currentDay++)
       {  %>
        <%=Html.CheckBox("TimeRange" + currentDay.ToString())%>
    <%} %>

不知怎的，我需要做的检查复选框如果模型包含基于2个参数的数据（我只是把第一个循环那里）

Somehow I need to make the checkbox checked if the model contains data based on 2 parameters (i just put the first loop there)

木田，如：

<%= Html.CheckBox("TimeRange..", (bool)Model.Timetable.Contains(x => x.Time == timeval && x => x.DayOfWeek = i))%>

如何做呢？

推荐答案

我任何你想要 任何 而不是 包含 和你的语法有点过。试试这个：

I any you want Any rather than Contains, and your syntax is a bit off. Try this:

Model.Timetable.Any(x => x.Time == timeval && x.DayOfWeek == i)

请注意，它只有一个拉姆达前pression，所以只有一个 X =＆GT; 位，同时注意 == 而不是 = 中的第二个条件。

Note that it's just one lambda expression, so there's only one x => bit, and also note the == instead of = in the second condition.
