how to use string.join to join value from an object array?

Question

I have an array of object e.g:

MyObject[] objs;

and within MyObject it contains a string property,

object[0].stringValue

If I want to join the whole array of objects by their stringValue, how can I do it?

Fiora, is that you?!?!

Note that pre-.Net 4.0, you need to convert it to an array like so: string.Join(",",objs.Select(w=>w.stringValue).ToArray()).

Do you mean to use string.Join to concatenate a property from multiple MyObject objects into one single string?

Then:

string str = string.Join(",", objs.Select(x => x.SomeProperty));
