MVC多层次关系 [英] MVC multi level relationships

问题描述

我有一个如下所示的父子关系：

Groups-> Properties-> SubProperties-> Values。



这是追踪数据的最佳方式。

i知道这是一个解决方案：

I have a parent child relation ship like below :
Groups->Properties->SubProperties->Values.

Which is the best way to follow to retrive the data.
i know this as a solution :

foreach(Group grp in grplist)
    {
       fetch the properties of(grp);
       foreach(property prp in prplist)//loop through the properties list 
       {
           fetch the sub properties of (prp)
           foreach(subproperty subprp in subprplist)
           {
              fetch the values of (subprp)
           }
       }
    }

所有上述foreach意味着一个linq查询





请建议最佳实践。

all the above foreach means a linq query


Please suggest the best practice.

推荐答案

假设您正在使用Entity Framework，解决方案是禁用延迟加载。然后通常在运行查询时使用Include方法。

Assuming you are using Entity Framework, the solution is to disable lazy loading. You do then normally by using the Include method when running your query.
