I have a collection of objectAs in a list. There is an objectB within the objectA. I want to sort the list by objectB.Prop1 but i keep getting a null reference when it sorts through the list.
This is what I have in my code:
data.OrderBy(c =>c.obj.Name);
I know I'm getting the null reference because some of the items have obj
null. I have thought of separating the list into two: one with null obj, and one that has an object for obj then sort, then concat afterwards. But I am wondering if there is a better way to do that.
这会有所帮助吗?
data.OrderBy(c => c.obj != null? c.obj.Name : "");
