LINQ查詢如果聲明

Question

好吧我嘗試做Linq中的一個if語句，並想知道是否有可能做這樣的事情：提前

  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} 

感謝。

這裏是查詢，如果任何人有這個相同的問題：

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)}

我不知道VB的，但在C＃中是將

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

我承擔將有VB.NET的三元語法
