I'm working on a desktop application in C# forms.I need this List of Banks in a combobox as drop down list, like this one.
I've populated the combobox drop down list myself. But I want to fetch that list from the given link.I've search on google and found few answers but they are not helping.

I tried to get that data by using following code but I only got some html like contents in result.

System.Net.WebClient wc = new System.Net.WebClient();
string webData = wc.DownloadString("http://www.pakwatan.pk/banks-pakistan/");
cbBankName.DataSource = webData.ToList();

I don't know how to extract require contents from result in webdata.
someone please help.
