How to get the MemberGroups for a Member?

Hello,

I succeeded in getting a list of Members of a specific MemberType. But now I would like to get the MemberGroups for each member

IMemberService memberService = Services.MemberService;

var students = memberService.GetMembersByMemberType(1044);

@foreach(var student in students)
{
var groups = ""; /*get the membergroups for student*/

        <tr>
          <th scope="row">@student.Id</th>
          <td>@student.Name</td>
          <td></td>
          <td></td>
        </tr>
    }

I can't find a clue in the documentation.

Any suggestions?

Hi Garret,

Umbraco relies on build-in logic in ASP.NET. While it still ought to be documented, that may be why it isn't as it's not directly a part of Umbraco.

Anyways, you can use the Roles class. Given that your example is a Razor view, you don't have to import the class. Usage would be as shown below:
```
string[] roles = Roles.GetRolesForUser(member.Username);
```
The method will return a string array of the roles of the member. The method will hit the database, so it may be slow when looking up the roles for a lot of members.

If you need a reference to the member group instead of just the name, you can use the member group service:
```
IMemberGroup group = Services.MemberGroupService.GetByName(name);
```
Or to avoid duplicate calls to the member group service, get all member groups, and then create a dictionary for faster lookups:
```
    Dictionary<string, IMemberGroup> memberGroups = Services.MemberGroupService
        .GetAll()
        .ToDictionary(x => x.Name);
```

Thanks Anders,

Thanks finally got it working. I thought I already tried your suggestion..but I got the error that IMember didn't have a property Username. But copy/pasting your code worked perfectly.

Maybe made a typo "UserName" instead of "Username".

Thanks anyway, you really helped a struggling Umbracian out!

Just as an update, it's also possible through the Member Manager
