按用户角色和附属ID获取用户

Question

In ASP.NET Identity we have following tables

• AspNetUsers
• AspNetRoles
• AspNetUserRoles

Additionally I added the following column to the AspNetUsers table

• Subsidiary_ID

Now I want to load a list with following filters

• RoleName == "Approver"
• Subsidiary_ID == "04"

So for that purpose I'm trying to write query like below

List<AspNetUser> approverprofiles = db.AspNetUsers.Where(w => w.Subsidary_ID == "04").Where(w => w.Name == "Approver").ToList();

but then I'm getting this error

'AspNetUser' does not contain a definition for 'Name' and no extension method 'Name'

Answer 1

You are searching for roleName in AspNetUsers table, that does not exist. If you want to get the users that have Subsidiary_ID == "04" and they are in role with RoleName == "Approver" then you must query like this:

 List<AspNetUser> approverprofiles = db.AspNetUsers
    .Where(w => w.Subsidary_ID == "04" && w.Roles.Any(r => r.Name == "Approver"))
    .ToList();
