Cast object type in a LINQ statement

Question

I have a Layer collection which contains a Content object as a property. How do I cast this Content to its original object to get its property in LINQ statement?

For example:

var item = Layers.FirstOfDefault(x =>(PushPin)x.Content.Description == "xyz");

In this case Content is of PushPin object type and I want to compare its Description property to xyz

Answer 1

If Content can be something other than PushPin then you will need something along the lines of

var item = Layers.FirstOrDefault(x => x.Content is PushPin && ((PushPin)x.Content).Description == "xyz");
