Why doesn't this string.Format() return string, but dynamic?

Question

@{
    ViewBag.Username = \"Charlie Brown\";
    string title1 = string.Format(\"Welcome {0}\", ViewBag.Username);
    var title2 = string.Format(\"Welcome {0}\", Vi         


        

Answer 1

It's the view bag which is dynamic.

If you use actual username (instead of ViewBag.UserName)it would work. Or cast (string)ViewBag.Username into string.
