LINQ Lambda

Lambda-expression Paging query

  //Paging Query            varDemo4 = db. Ldc_goods_brand.where<ldc_goods_brand> (UU = uu. Id >0)                //. Orderby<ldc_goods_brand, int> (UU = uu. ID);//Ascending. OrderByDescending (UU = uu. ID)//in descending order. Skip<ldc_goods_brand> (2)//How many lines are crossed?. Take<ldc_goods_brand> (2);//How many bars are taken?//command-type programming functional Programming            #endregion
