The UserService acts as a "gateway" to Umbraco data for operations which are related to Users.

• Namespace: Umbraco.Core.Services

• Assembly: Umbraco.Core.dll

All samples listed in this document will require references to the following dll:

All samples in this document will require the following using statements:

Getting the service

Services property

If you wish to use the UserService in a class that inherits from one of the Umbraco base classes (eg. SurfaceController, UmbracoApiController or UmbracoAuthorizedApiController), you can access the service through a local Services property:

IUserService userService = Services.UserService;

Dependency Injection

In other cases, you may be able to use Dependency Injection. For instance if you have registered your own class in Umbraco's dependency injection, you can specify the IUserService interface in your constructor:

public class MyClass
{

    private IUserService _userService;
    
    public MyClass(IUserService userService)
    {
        _userService = userService;
    }

}

Static accessor

If neither a Services property or Dependency Injection is available, you can also reference the static Current class directly:

IUserService userService = Umbraco.Core.Composing.Current.Services.UserService;

Samples

• Create a new user Quick sample showing how to create a new backoffice user; including setting a password, assigning the user to a user group, and setting the name of the user.

If you want to create a new user, you'd use ASP.NET identity APIs like it is used in core.

Assigning the user to a user group

Permissions aren't administered for the specific user, but rather for the user group(s) that the user is a part of. So to add our new user to a user group, we first need to get a reference to the user via the GetUserGroupByAlias method, and then use the AddGroup method for adding the group to our user:

To make sure that these changed are saved to the database, we must also make sure to call the Save method. The GetUserGroupByAlias method takes the alias of a user group - eg. admin for the default Administrators user group.
