SharePoint [user access control]-SharePoint determines whether the current user has certain permissions on the current page

The following code is used to determine whether the current user has the editing permission on the current page. The principle is to perform and operate on the page permissions, and then determine whether the page is blank: & representation and operation | representation or operation reference: http://msdn.microsoft.com/en-us/library/microsoft.sharepoint.sproledefinition.basepermissions.aspx

Bool haveeditpermission = true; If (spcontext. Current. Web. currentuser! = NULL & spcontext. current. contextpageinfo. basepermissions. hasvalue) {// determine whether the current user has the permission to edit the current page if (spcontext. current. contextpageinfo. basepermissions. value & spbasepermissions. editlistitems )! = Spbasepermissions. emptymask) {haveeditpermission = true ;}}

Note: When you call base. setpersonalizationdirty () to set the webpart attribute, you do not need to judge the user permissions. Users without permissions will not be set successfully.
