Question

Lets suppose that I have the following simple query

var q = 
    from p in products
    orderby p.ProductName descending
    select p;

What would be the simplest and most straightforward way to specify the sort field and direction at runtime?

Answer 1

We’ve used the dynamic linq library before to do this. Here’s a link to Scott Guthrie’s blog where he describes it.

Basically you could alter the above query to look like this:

var q = db.Products
        .OrderBy("ProductName Descending")
