示例1: ApplyAndExecute

        {
            queryable = this.ApplyExpressions(queryable);
            var projection = this.Projection;
            if (projection == QueryProjection.AsEnumerable)
            {
                IList limitedQueryable;

                        .Cast<object>()
                        .Skip(Skip)
                        .Take(Top)
                        .Cast(queryable.ElementType)

                else
                {
                    if (this.Skip > 0)

                    limitedQueryable = queryable.ToListDetectType();
                }

                var previous = GetPageLink(this.Url, this.Skip, this.Top, limitedQueryable.Count, totalCount, -1);
                var next = GetPageLink(this.Url, this.Skip, this.Top, limitedQueryable.Count, totalCount, 1);

                var qr = QueryResult.Create(limitedQueryable, this.Skip, totalCount, previous, next);
                return new PomonaResponse(this, qr);
            }

            try
            {
                var result = queryable.Execute(projection);
                return new PomonaResponse(this, result);
            }
            catch (InvalidOperationException)
                when (projection == QueryProjection.First || projection == QueryProjection.Last || projection == QueryProjection.Single)
            {
                // We assume that this means no matching element.
                // Don't know another way to check this in a non-ambigious way, since null might be a valid return value.
                return new PomonaResponse(this,
                                          PomonaResponse.NoBodyEntity,
                                          HttpStatusCode.NotFound);
