sustring test puzzle

I have the following string: \\?\hid#vid_04d8pid_003f#62edf110800000#{4d1e55b2-f16f-11cf-88cb-001111000030 stored in a string variable (from a function call) called devPathName

and the following defined:

Code:

---

const string myDevice = @"vid_04d8pid_003f";

---

but the following:

Code:

---

Boolean test;               
test = devPathName.Contains(myDevice);
statusLabel.Text += "\n\tThe value of test: " + test.ToString();

---

always evaluates to false.

Print both string so you're 100% certain they contain what you think they contain.

I did.. No change

Attempting to extract a path from the string (using Path.GetFullPath) causes and exception which says the string contains the illegal characters '\r' and '\n'. Is there a way to remove these escape sequences from the string?
I've already tried to replace 'em using the string.replace() method.
