Checking user permission for lists

Scenario:
You want to check user permission on all the lists
Solution:
You can develop a webpart and using object model you can check that.

Code:

StringBuilder sb = new StringBuilder();
sb.Append("<UL>");

SPSite sitecol = SPContext.Current.Site;
SPWeb site = SPContext.Current.Web;
SPUser user = SPContext.Current.Web.CurrentUser;

SPSecurity.RunWithElevatedPrivileges( delegate() {
  using (SPSite elevatedSiteCol = new SPSite(sitecol.ID))  {
    using (SPWeb elevatedSite = elevatedSiteCol.OpenWeb(site.ID)) {
       foreach (SPList list in elevatedSite.Lists) {
         if (list.DoesUserHavePermissions(user,SPBasePermissions.ViewListItems))
         {
            sb.Append("<LI><a href='" + list.RootFolder.Url + "'>" + list.Title + "</a></LI>");
         }
         else
         {
            sb.Append("<LI style='color:red'>" + list.Title + "</LI>");
         }
       }
     }
   }
 }
);

sb.Append("</UL>");
