实例说明asp.net中的简单角色权限控制

角色表+用户表,其中Hope_T_User(用户)中的User_RoleId关联Hope_T_Role(角色)的Role_Id，表中字段均为简单常见英文，不作详解。

主要思路是使用公共类在其中根据角色得出其越权时的操作，然后后台所有需要验证权限的页面均继承此类，使用相应参数判断角色以做相应操作。

公共类：AdminPermission
代码如下:
/// <summary>
/// AdminPermission角色权限验证类
/// </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;//是否允许访问
if (Session["HopeUser"] == null)
{
isAllowAccess = false;
}//Session不存在时
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;
}
else
{
switch (objEnumRole)
{
#region
case (enumRole.Role_PostArticle):
if (role.Role_PostArticle != "1")
isAllowAccess = false;
else
isAllowAccess = true;
break;

if (role.Role_ManageArticle != "1")
isAllowAccess = false;
