Hi, I have the following code:

C#

public void Sort()
{

    Collection = (from pricing in Collection orderby pricing.Prices.Price select pricing).ToList();

}

The problem is I get a null reference error when any of the values in the list is null.

It works just fine when all values are not null.

how do I overcome this error?

Thanks!

What do you want to do with the null values? Exclude them? Or put the at the and of the list?

You can exclude the null values like this:

C#

Collection = (
    from pricing in Collection 
    where pricing != null && pricing.Prices != null
    orderby pricing.Prices.Price 
    select pricing).ToList();
