	string username,

Return Value

Type: System.Web.Security.MembershipUser
A MembershipUser object for the newly created user. If no user was created, this method returns null.

CreateUser adds a new user to the data store and returns a MembershipUser object for the newly created user. If the user creation fails, you can retrieve a MembershipCreateStatus value from the status output parameter that indicates why user creation failed. You can specify a unique identifier for the user, such as a primary key value for a database, by using the providerUserKey parameter.

The CreateUser method will return null if password is an empty string or null, username is an empty string or null or contains a comma (,), passwordQuestion is not null and contains an empty string, or passwordAnswer is not null and contains an empty string.

Once a membership user has been created and you have a reference to a MembershipUser object for that user, you can modify the settings for that user with the MembershipUser public methods and by setting the property values of the MembershipUser object and then passing the MembershipUser object to the UpdateUser method.

If a user already exists in the data source for the application, you can obtain a MembershipUser object for the existing user with the GetUser method.

Leading and trailing spaces are trimmed from all string parameter values.
