Why do I get null instead of empty string when receiving POST request in from Razor View?

Question

I used to receive empty string when there was no value:

[HttpPost]
public ActionResult Add(string text)
{
    // text is \"\" when there\'s no value provided         


        

Answer 1

The default model binding will create a new SomeModel for you. The default value for the string type is null since it's a reference type, so it's being set to null.

Is this a use case for the string.IsNullOrEmpty() method?
