有没有办法可以异步运行 Database.SqlQuery? [英] Is there a way I can run a Database.SqlQuery as async?

问题描述

我有以下几点:

var sql = @"Select 
                case when Test.TestTypeId = 1 then Exam.Name
                     when Test.TestTypeId = 2 then Topic.Name
                end as Name,
                Test.Title,
                Test.TestId,
                Test.QuestionsCount
            FROM Test
            LEFT JOIN Exam ON Test.ExamId = Exam.ExamId
            LEFT JOIN Topic ON Test.TopicId = Topic.TopicId
            WHERE Test.TestStatusId = 1 -- Current";
var tests = db.Database.SqlQuery<TestDTO>(sql).ToList();

我正在为此寻找一种异步方法，但它似乎不存在.有没有办法让我可以异步运行?

I was looking for an async method for this but it does not seem to exist. Is there a way that I can run this async?

推荐答案

如果你使用 Entity Framework 6 你只需要指定

If you're using Entity Framework 6 you just need to specify

using System.Data.Entity;

在文件的顶部.

ToListAsync 是 IQueryable 上的一个扩展方法，在 System.Data.Entity.QueryableExtensions

ToListAsync is an extension method on IQueryable<T> declared in System.Data.Entity.QueryableExtensions
