If (u! = NULL) // determine whether the user has logged on

{

String currentuserid = U. provideruserkey. tostring (); // because the value of provideruserkey is of the guid type, you must use the tostring () method to obtain the string value.

String email = U. Email;

String passwordquestion = U. passwordquestion;

}

Example 2 (create a new user ):

Membershipcreatestatus status;

Protected void button#click (Object sender, eventargs E)

{
