Question

what will be the regular expression for a table with class name tn_result?

I have tried two expressions given below but neither is working. What is wrong with them? How can I make this work?

 string TableExpression = "<TTable class=\"tn_results\">(.*?)</table>";

See this answer on why this is a bad idea.

The answer depends on whether you need to get this table server-side or client-side.

On the client, use jQuery:

var table = $('table.tn_result');

On the client, if you’re using ASP.Net WebForms, it will probably be easiest to add runat="server" and id attributes on the table(s) you want to get. Then you can just get them in the code-behind like any other control:

var table = this.TableId; //not really required, but hopefully makes things clear
if(table.Attributes["class"].Contains("tn_result"))
{
    // do something with the table
}
