Linq to sql LINQ问题-如何在哪里制作！=价值

我有一个表“Friends”，其中包含登录用户的ID和他/她的朋友的ID

使用此SQL查询得到的结果

SELECT u.ID, u.Nickname 
FROM UserSet as u, FriendsSet as f
WHERE u.ID=f.FriendID
ORDER BY u.Nickname

是

“rugardini”是我的当前用户，因为在友谊关系中，“Teste”是我的朋友，我也是他的朋友，但在我的朋友列表中，我不希望出现我自己的用户

因此，我做了以下查询，不包括我自己的ID（16）

我有两个问题：

1） 这是做这个选择的最好方法吗？ 2） 如何将此SQL查询转换为LINQ？

关于2）：第二个查询的LINQ应该如下所示：

from u in db.UserSet, f in db.FieldsSet
where u.ID=f.FriendID && u.ID != 16
orderby u.Nickname
select u.ID, u.Nickname 

var friends = (from u in db.UserSets
               join f in db.FriendsSets
               on u.ID equals f.FriendID
               where u.ID != userID
               orderby u.Nickname
               select new Friends { ID = u.ID, Nickname = u.Nickname }).ToList();

public class Friends
{
    public int ID;
    public string Nickname;
}

<ul>
@foreach (dynamic item in ViewBag.Friends)
{
    <li>@item.Nickname @Html.ActionLink("Amigo", "Index", new { id = item.ID })</li>
}
</ul>

关于2）：第二个查询的linq应该如下所示：

from u in db.UserSet, f in db.FieldsSet
where u.ID=f.FriendID && u.ID != 16
orderby u.Nickname
select u.ID, u.Nickname 

var friends = (from u in db.UserSets
               join f in db.FriendsSets
               on u.ID equals f.FriendID
               where u.ID != userID
               orderby u.Nickname
               select new Friends { ID = u.ID, Nickname = u.Nickname }).ToList();

public class Friends
{
    public int ID;
    public string Nickname;
}

<ul>
@foreach (dynamic item in ViewBag.Friends)
{
    <li>@item.Nickname @Html.ActionLink("Amigo", "Index", new { id = item.ID })</li>
}
</ul>

我只能这样执行查询：

from u in db.UserSet, f in db.FieldsSet
where u.ID=f.FriendID && u.ID != 16
orderby u.Nickname
select u.ID, u.Nickname 

var friends = (from u in db.UserSets
               join f in db.FriendsSets
               on u.ID equals f.FriendID
               where u.ID != userID
               orderby u.Nickname
               select new Friends { ID = u.ID, Nickname = u.Nickname }).ToList();

public class Friends
{
    public int ID;
    public string Nickname;
}

<ul>
@foreach (dynamic item in ViewBag.Friends)
{
    <li>@item.Nickname @Html.ActionLink("Amigo", "Index", new { id = item.ID })</li>
}
</ul>

在我的控制器中有这样一个类：

from u in db.UserSet, f in db.FieldsSet
where u.ID=f.FriendID && u.ID != 16
orderby u.Nickname
select u.ID, u.Nickname 

var friends = (from u in db.UserSets
               join f in db.FriendsSets
               on u.ID equals f.FriendID
               where u.ID != userID
               orderby u.Nickname
               select new Friends { ID = u.ID, Nickname = u.Nickname }).ToList();

public class Friends
{
    public int ID;
    public string Nickname;
}

<ul>
@foreach (dynamic item in ViewBag.Friends)
{
    <li>@item.Nickname @Html.ActionLink("Amigo", "Index", new { id = item.ID })</li>
}
</ul>

在我看来，一个循环是这样的：

from u in db.UserSet, f in db.FieldsSet
where u.ID=f.FriendID && u.ID != 16
orderby u.Nickname
select u.ID, u.Nickname 

var friends = (from u in db.UserSets
               join f in db.FriendsSets
               on u.ID equals f.FriendID
               where u.ID != userID
               orderby u.Nickname
               select new Friends { ID = u.ID, Nickname = u.Nickname }).ToList();

public class Friends
{
    public int ID;
    public string Nickname;
}

<ul>
@foreach (dynamic item in ViewBag.Friends)
{
    <li>@item.Nickname @Html.ActionLink("Amigo", "Index", new { id = item.ID })</li>
}
</ul>

@foreach（ViewBag.Friends中的动态项）
{
@item.昵称@Html.ActionLink（“Amigo”，“Index”，new{id=item.id}）
}

您的查询目前没有任何内容可以识别当前用户。请发布更多关于您的表结构的详细信息-我认为您目前没有向我们提供足够的信息。请创建当前用户的实例，并用它替换
