关于MemerberShip角色的使用

关于MemerberShip角色的使用

1.     常用函数：

1）        Membership.CreateUser(用户名，密码)

2）        判断用户是否被锁定：User.IsLockedOut()

3）        判断用户是否为某种角色：Roles.IsUserInRole(用户名,角色名)

4）        将某一用户添加到某一角色中：Roles.AddToRole(用户，角色)

5）        将用户从某一角色中移除：Roles.RemoveUserFromRole(用户名，角色)

还有其他很多，这里就不一一列举了，大家可以去MSDN上查。
