Display values of NameValueCollection in Debugger

I have a NameValueCollection with string keys and string values, like this:

fields["fieldname"] = "string value"

When I add a WATCH in VS20217 for "fields" it lets me expand a list of keys, but I don't seem to be able to get to the values unless I add an individual watch for each key.

I seem to recall doing this thing in the past but can't recall the method. Can anybody help?

The low-friction approach would be to create an extension method first:

public static string DebugView(this NameValueCollection nvc)
{
    return string.Join("\r\n", nvc.AllKeys.Select(key => $"{key}: {nvc[key]}"));
}

Then put nvc.DebugView() as your watch variable, or capture that string to a variable and put a watch on that instead of the NameValueCollection itself.
