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

You can use the DisplayFormat attribute on the property of your model class:

[DisplayFormat(ConvertEmptyStringToNull = false)]
