Question

我有这个查询，而且我无法转换为lambda表达式

SELECT [dbo].[Prospects].[Id]
  ,[UserId]
  ,[NewId]
  ,[dbo].[Prospects].[Status]
  FROM [dbo].[Prospects]  join [dbo].[User] on [dbo].[User].Id = [dbo].      [Prospects].UserId
  where [dbo].[Prospects].NewId = 3 and [dbo].[User].IsActive = 1

这就是我得到的，但它不起作用

 var result = Workspace.Prospects.Join
            (Workspace.Users, pros => pros.UserId,
            use => use.Id, (pros, use)
            => new { Prospect = pros, User = use}).Where
            (both => both.User.IsActive == true && both.Prospect.NewId == idVacante)
            .OrderBy(both => both.Prospect.Id).AsEnumerable().ToList();
 List<Prospect> prospects = result.Cast<Prospect>().ToList();

这并不难。您可以在加入表之前过滤表

var result = Workspace.Prospects.Where(x=> x.NewId == 3)
                  .Join(Workspace.Users.Where(x => x.IsActive == 1),
                          p => p.UserId,
                          u => u.Id,
                          (p, u) => new { p.Id, p.UserId, p.NewId, p.Status })

使用连接和where子句
