Examples illustrate simple role rights control in asp.net-practical skills

Role table + User table, where Hope_t_user (user) in the User_roleid Association Hope_t_role (role) of role_id, the table in the fields are simple common English, not to be detailed.

The main idea is to use the public class in which the role of the operation of the ultra vires, and then all the pages need to verify the permissions of the page to inherit this class, use the corresponding parameters to determine the role to do the appropriate action.

public class: Adminpermission

Copy Code code as follows:

<summary>
Adminpermission Role Permission Validation class
</summary>
public class AdminPermission:System.Web.UI.Page
{
Hope.BLL.Hope_T_Role bllrole = new Hope.BLL.Hope_T_Role ();
protected void Checkuserpermission (Enumrole objenumrole)
{
BOOL isallowaccess=false;//Whether access is allowed
if (session["hopeuser"] = = null)
{
Isallowaccess = false;
When}//session does not exist
Hope.Model.Hope_T_User objuser= (Hope.Model.Hope_T_User) session["Hopeuser"];
int roleid=0;
if (objuser!= null)
{
Roleid = Convert.ToInt32 (Objuser.user_roleid);
}
Hope.Model.Hope_T_Role role = Bllrole.getmodel (Roleid);

if (role = = null)
{
Isallowaccess = false;

Add the following code to the page you want to verify

Copy Code code as follows:

Public partial class manage_manage_user_add:adminpermission//inheriting common classes
{
protected void Page_Load (object sender, EventArgs e)
{
if (! IsPostBack)
{
Checkuserpermission (Enumrole.role_manageuser);//Verify Permissions
}
}
...
}

This role privilege module is a simple module, which can be subdivided into role-user-role function (-single user function) model according to the actual project requirement.
