Thanks for your respones Thom,
Yes, the FileStream should be closed which I missed. As for using Uri class
or directly string operation, it is another story which somewhat related to
the concept of URI (URN and URL) , and here, there is no critical concerns
on using Uri or just string path. Sometimes, when we don't know the path
string in advance(dynamically generate URL from string...), using Uri class
can help avoid including some invalid chars which may cause security issue.
Thanks,

| This isn't quite what I needed. This is EXACTLY what I needed.
|
| The input stream needs to be closed.
|
| What is the advantage in defining a Uri that used once vs. just using the
| string without the Uri creation?
|
| Thank you for the help. (My original attempt had a bug that I found
after
| seeing yours solution.)
