Replacing string in c# to block skype phone formatting

Question

I have two strings:

 string ThePhone = "XXX-XXX-XXXX"
 string SkypeBlock = "-<span style='display:none;'>-</span>";

I want to replace the last dash (-) in ThePhone with SkypeBlock

And the desired result:

TheNewPhone = "XXX-XXX-<span style='display:none;'>-</span>XXXX"

How?

Here is your solution

var ThePhone = "XXX-XXX-XXXX";
var SkypeBlock = "<span style='display:none;'>-</span>";
var lastDash = ThePhone.LastIndexOf('-'); // Find position of the last dash
var theNewPhone = thePhone.Remove(lastDash, 1).Insert(lastDash, SkypeBlock); // Replace last dash

Ok, thanks. However, I'm still struggling with the quotations; the line is underlined red. – frenchie Nov 23 '11 at 02:49
Ok, I got it with the @ symbol. There's still a problem: it truncates the last 4 digits! – frenchie Nov 23 '11 at 02:55

I guess this should do the trick:

string ThePhone = "XXX-XXX-XXXX";
string SkypeBlock = "-<span style=\"display:none;\">-</span>";

ThePhone = ThePhone.Substring(0, 8) + SkypeBlock + ThePhone.Substring(8, 4);
