document.doctype is always returning null c#

[jambalapamba]

HI

i am trying to get the doctype of a html document using the following code

document = (HTMLDocument)w ebBrowser.Docum ent;
string url = document.url; // This line is working
string doctype = document.doctyp e.ToString();//this line is always null

am i implementing doctype correctly or do i have to do differently.Can any one please help me.

Maybe there is no doctype given for the document?
