Extend a Class

[shapper]

Hello,

I have the following code:

public static class HtmlHelperExtensions {

public static string ToolTip(this HtmlHelper helper, string name)
{
return ToolTip(helper, name, null, null);
}
...

HtmlHelper is a class in System.Web.MVC.

Instead of having the ToolTip inside a new class named
HtmlHelperExtenstions can I make my ToolTip method to some how extend
the HtmlHelper, i.e., to be also inside "HtmlHelper'?

And if yes, should I do this?

Thanks,
Miguel

If you don't control HtmlHelper, then no. However, if you ensure that
HtmlHelperExtensions is in the sample namespace as HtmlHelper, then
the extension method will be available (assuming you have a "using"
for that namespace).
