Regular Expressions .NET

I am new to regular expressions with .net. I was wondering if someone
could help me out.

I'm looking for the lines of code that will replace C: with
nothing(""), AND all backslashes"\" to forward slashes"/".

Example:

ORGINAL

x:\en\aviation\users.htm

FINISHED PRODUCT

/en/aviation/users.htm

It would be awesome if I could hear from someone on this matter.

Thanks!

You mean something like:

        Dim str As String = "C:\en\aviation\users.htm"
        str = Regex.Replace(str, "C:", "")
        str = Regex.Replace(str, "\\", "/")
        MsgBox(str)

Note, the following does the same thing:

        Dim str As String = "C:\en\aviation\users.htm"
        str.Replace("C:", "")
        str.Replace("\\", "/")
        MsgBox(str)

Thanks,

Seth Rowe

Oops, change "\\" to "\" Making it:

         Dim str As String = "C:\en\aviation\users.htm"
         str.Replace("C:", "")
         str.Replace("\", "/")
         MsgBox(str)

Using Regex.Replace requires using double backslashes as a backslash
has special meaning to Regex. This cause str.Replace("\\", "/") to look
for 2 backslashes instead of just one.

Seth,
Try:

> Dim str As String = "C:\en\aviation\users.htm"

str = str.Replace("C:", "")
str = str.Replace("\", "/")

> MsgBox(str)

As String.Replace is a function that returns the modifed string.

Removing the drive letter can be done with a regular expression:

path = Regex.Replace(path, "^[A-Z]:", "")

Replacing the backslashes can be done with just a regular replace.
