Coalesce operator in C#?

Question

I think i remember seeing something similar to the ?: ternary operator in C# that only had two parts to it and would return the variable value if it wasn't null and a default value if it was. Something like this:

tb_MyTextBox.Text = o.Member ??SOME OPERATOR HERE?? "default";

Basically the equivalent of this:

tb_MyTextBox.Text = o.Member != null ? o.Member : "default";

Does such a thing exist or did I just imagine seeing this somewhere?

Answer 1

Yup:

tb_myTextBox.Text = o.Member ?? "default";
