有条件地添加限制

我有非常复杂的标准。让我们看看下面的标准:

         new List < ICriterion > {
            Restrictions.Not(Restrictions.Eq("Name", user.Name)),
            Restrictions.Or(
               Restrictions.And(
                  Restrictions.And(                 
                     Restrictions.Eq("Status", user.Status))
                     ...
                ))
                ...
         };

但是我需要根据一个设置有条件地添加一个限制。

    if(Setting.SomeSettings)
        {
           new List < ICriterion > {
                    Restrictions.Not(Restrictions.Eq("Name", user.Name)),
                    Restrictions.Or(
                       Restrictions.And(
                          Restrictions.And(
                            **//new restriction**
                             Restrictions.Eq("Some", user.Some))
                             Restrictions.Eq("Status", user.Status))
                             ...
                        ))
                        ...
                 };
        }
        else
        {
           new List < ICriterion > {
                    Restrictions.Not(Restrictions.Eq("Name", user.Name)),
                    Restrictions.Or(
                       Restrictions.And(
                          Restrictions.And(                 
                             Restrictions.Eq("Status", user.Status))
                             ...
                        ))
                        ...
                 };
        }

如何避免这种重复?

         ICriterion criterion;
         if(Setting.SomeSettings)    
         {
           criterion = Restrictions.And(
                            **//new restriction**
                             Restrictions.Eq("Some", user.Some))
                             Restrictions.Eq("Status", user.Status))
                             ...
                        ));
        }
        else
        {
           criterion = Restrictions.And(
                          Restrictions.And(                 
                             Restrictions.Eq("Status", user.Status))
                             ...
                        ));
        }
        new List < ICriterion > {
                    Restrictions.Not(Restrictions.Eq("Name", user.Name)),
                    Restrictions.Or(
                       Restrictions.And(
                        criterion   
                        ...
                 };
