ClientContext clientContext = new ClientContext(_siteurl);
clientContext.AuthenticationMode =ClientAuthenticationMode.Default;
clientContext.Credentials = new System.Net.NetworkCredential(“peakfinders”, “password@1”, “peakfinders”);
Web oweb = clientContext.Web;
            List myList = oweb .Lists.GetByTitle("Employee");

            roles = oweb.LoadQuery(
            myList.RoleAssignments.Include(
            roleAssign => roleAssign.Member,
            roleAssign=> roleAssign.RoleDefinitionBindings.Include(
            roleDefine => roleDefine.Name, // for each role def, include roleDef’s Name
