Question

I have 2 Tables that is m to n relationships between them. Roles, Moduls, ModulsInRoles. I get current user roles. IAnd I want to get these roles’ moduls. I tried to write something. But I cant success.

string[] roller = System.Web.Security.Roles.GetRolesForUser();

IEnumerable<TblModuller> moduller = null;
IEnumerable<TblModulsInRoles> moduls_in_roles = null;

foreach (var rol in roller)
{
     moduls_in_roles = entity.TblModulsInRoles.Where(x => x.Roles.RoleName == rol);
     foreach(var modul in moduls_in_roles)
     {
         //I dont know What should I write or this code is correct.
     }
}

for example; My data is like this:

Admin  Modul1
Admin  Modul2
User   Modul2
User   Modul3

And I want to get this:

Modul1
Modul2
Modul3

What is the logic? and Is there some code example or tutorial about this topic.

Thanks.

Try This

var modullerList = new List< TblModuller>();

foreach (var rol in roller)
{
     moduls_in_roles = entity.TblModulsInRoles.Where(x => x.Roles.RoleName == rol);
     foreach(var modul in moduls_in_roles)
     {
        if(!modullerList .Contains(modul))
            modullerList .Add(modul);
     }
}
