Creating an instance of an object

Question

I've been trying to use this code but the null exception reference occurs
this is the code:

        public string _textBoxProperty
        {
 
            set
            {string str = webBrowser1.Document.GetElementById("Age").InnerText;
              str= value; }
            get { return webBrowser1.Document.GetElementById("Age").InnerText; }
        }

its function is a bit complicated so I avoided telling it,
I would be obliged if someone helps me out.

Do you in fact need a 'set' here as there appears to be no backing field? Perhaps just a 'get' will suffice: public string _textBoxProperty { get { return webBrowser1.Document.GetElementById("Age").InnerText; } } Also the Document property will return null if no page is currently loaded and GetElementById will return null if the id can't be found. To guard against these possiblities, I'd change the code to: public string _textBoxProperty { get { HtmlDocument doc = webBrowser1.Document; if( doc != null && doc.GetElementById("Age") != null) { return doc.GetElementById("Age").InnerText; } else { return ""; // empty string say } } }
