Answer 1

The name of field in your table is very important I see that your join field name is correct in your database as I see in picture very simply you can use linq query for fetching your purpose for example use 'userreferral'. user and fetch the field of user table. if you want more help plz comment me.

Answer 2

在您的选择查询中使用此模式

 UserEmail =x.UserReferral.ReferralCode
