Query users

This topic contains examples of how to:

• Query a single user
• Query all users
• Query user by first name

To query a specific user, you must perform the following:

1. Get instance of the user manager.
   The manager is represented by the UserManager class. For more information about getting the instance, see For developers: Users.
2. Get the user.
   To get the specified user, call the GetUser method of the UserManager class. It has two overloads:
• GetUser(string username) – returns the user with the specified username.
• GetUser(Guid id) – returns the user with the specified ID.

NOTE: To learn how to query the profile of the user, read For developers: Query user profiles.

To query all users, you must perform the following:

1. Get instance of the user manager.
   The manager is represented by the UserManager class. For more information about getting the instance, see For developers: Users.
2. Get all users.
   To get all users, call the GetUsers method of the UserManager class.

However some of the fields of the user are no longer properties of the User class like first name and last name. Instead you should use the SitefinityProfile. Here is a sample code that demonstrates how to query all users by first name:
