问题描述

大家好请各位帮我了解一下asp.net mvc5,e.f 6默认使用 IQueryable IEnumrable ?我想使用 IQueryable 工作,因为它最适合底层数据库。我正在使用LINQ to entity方法和var关键字来保存linq结果。默认情况下,我的模型类的类型为 public< dbset> className {get;设置} 所以这里< DbSet> 返回 IQueryable IEnumrable

请帮助我

我试过谷歌但仍未找到

Hi everyone please help me to understand about asp.net mvc5 with e.f 6 is used IQueryable or IEnumrable by default? I want to work using IQueryable because it is best for underlying database. I am using LINQ to entity approach and var keyword for holding linq results. By default my model classes is of type public <dbset> className {get; set} so here <DbSet> returns IQueryable or IEnumrable?
kindly help me

推荐答案

using (var context = new ProductContext()) 
{     
    // This does not execute the query, but rather just configures it.
    // The result is very much like IQueryable.
    var query = context.Where(e => [Something]).OrderBy(e => [Something]);

    // Once you force enumeration of the query you get an IEnumerable back.
    // It is enumerated by a foreach, ToArray, ToDictionary, ToList, or any 
    // linq operator such as First or Any
    IEnumerable<product> results = query.ToList();
}
