Question

Im trying to determine the content type of HtmlAgility.HtmlDocument. Any idea??

        HtmlWeb web = new HtmlWeb();
        var hDocument = web.Load(/*string*/ url);

I want to know how to find out the contentType of hDocument if possible, or if there is any work round it. Thanks

Basically what you want is the httpwebresponse object, to get this with hap you can use the taskcompletionsource class like this.

var web = new HtmlAgilityPack.HtmlWeb();
var tcs = new TaskCompletionSource<HttpWebResponse>();

web.PostResponse = delegate(HttpWebRequest request, HttpWebResponse response)
{
    tcs.SetResult(response);
};

var  document = web.Load("http://stackoverflow.com/");
var httpWebResponse = await tcs.Task;

var contentType = httpWebResponse.ContentType

I have not done this in a while and didn't get a chance to test this code but it should work for what you want.

Get HttpWebResponse from Html Agility Pack HtmlWeb https://learn.microsoft.com/en-us/dotnet/api/system.net.httpwebresponse.contenttype?view=netframework-4.7.2
