Question

好的我试着在Linq做一个if语句，并想知道是否有可能做类似的事情：

            Dim loadFriends = From p In db.UserRelationships Where p.aspnet_User.UserName = User.Identity.Name _
                          Or p.aspnet_User1.UserName = User.Identity.Name And p.Type = 1 _
                          Select New With {if p.aspnet_user1.user = "a certan username" then .username = _
                                          p.aspnet_user.username else .username = p.aspnet_user1.Username}

先谢谢。

谢谢tyrongower

这是查询是否有其他人有同样的问题：

Dim loadFriends = From p In db.UserRelationships Where p.aspnet_User.UserName = User.Identity.Name _
                          Or p.aspnet_User1.UserName = User.Identity.Name And p.Type = 1 _
                          Select New With {.username = If((p.aspnet_User1.UserName = User.Identity.Name), p.aspnet_User.UserName, p.aspnet_User1.UserName)}

Answer 1

我不知道VB但是在c＃中会是

 username = (p.aspnet_user1.user == "a certan username")? aspnet_user.username:p.aspnet_user1.Username

我假设VB.NET有三元语法

Linq Query If语句
