The MembershipCreateStatus enumeration indicates the success or failure of an attempt to create a new user. If the CreateUser operation fails, the MembershipCreateStatus enumeration describes the cause of the failure.


If you are not familiar with the membership features of ASP.NET, see Introduction to Membership before continuing. For a list of other topics related to membership, see Managing Users by Using Membership.

If you use a CreateUser method overload that does not specify an output parameter of type MembershipCreateStatus, an unsuccessful attempt to create a new user throws a MembershipCreateUserException with the StatusCode property set to one of the MembershipCreateStatus enumeration values.

The following code example creates a new user for an ASP.NET application configured to use forms authentication and ASP.NET membership. If the user is not created successfully, a message is displayed to the user. If the user is created successfully, the user is redirected to the login page for the application. This code example uses the MembershipCreateStatus enumeration to determine the message displayed to the user in the event of a failure.

No code example is currently available or this language may not be supported.
