Using Variables in XPath Expressions

I have a textBox that contains a string values. I need to take this
string and use it as criteria for an XPath Expression. Here's what I
have. Why isn't it working???

string s = textBox1.Text;
XPathExpression expr;
expr = myXPathNavigator.Compile("/NewDataSet/note[@to=$s]");

Hi Matt,

Can you check to see if something similar to the below works -

string filter = textBox1.Text;
String xpathExpression =
String.Format("/NewDataSet/note[@to='{0}']", filter);
XPathExpression expr = myXPathNavigator.Compile(xpathExpression);

Regards,
Aravind C
