How to sort item selected from database using LinQ to SQL in asp.net mvc c#

[dorddank]

I want to sort the price and the quantity of my product that query from database to show in my view. I throw the choice to the parameter string of URL (Products?availability=availabilityLowtoHigh&priceSort=priceLowtoHigh&tab=2).This is the linq-sql that I used:\[code\] public IList<Item> Sort(string availability,string priceSort) { IEnumerable<Item> ien_item; if (availability == "availabilityLowtoHigh" && priceSort == "priceLowtoHigh") { ien_item = from i in this.DataContext.Items orderby i.Quantity ascending orderby i.Price ascending select i; }else{ ien_item = from i in this.DataContext.Items orderby i.Quantity descending orderby i.Price descending select i; } }\[/code\]Detail : if the parameter of query string availability == "availabilityLowtoHigh" and priceSort == "priceLowtoHigh", so the product will show in the page by sorting the products that have a less to more quantity, and cheap price to expensive price.Can I used orderby twice in my query?
