具有非主键值的 FindAsync

FindAsync with non-primary key value(具有非主键值的 FindAsync)
本文介绍了具有非主键值的 FindAsync的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

public class Foo
{
     public int Id { get; set; }
     public int UserId { get; set; }
}

这似乎是异步执行此操作的方法:

This appears to be the way to do this asynchronously:

DatabaseContext db = new DatabaseContext();
Foo foo = await db.Foos.FindAsync(fooid);

如何根据 UserId 的值异步获取特定用户的所有 Foo?

How does one asynchronously get all of the Foos for a specific user based on UserId's value?

推荐答案

假设您使用的是 Entity Framework 6.0 (prerelease):

Assuming you are using Entity Framework 6.0 (prerelease):

var userId = ...;
var foos = await db.Foos.Where(x => x.UserId == userId).ToListAsync();
