Custom Format String

Question

Quick Question, I have something that I would like to implement a custom format string on like the Date/Time Object one. Basically, I just need it to find %P and replace it with something. Although, it would be great if I could easily expand it for other things. I found an article on MSDN but, I didn't make heads or tales of it. So if anyone could provide me with a sample or point me in the right direction, I'd 'preciate it!

Thanks!

Use a Regex:

VB

Public Dim regex As Regex = New Regex( _
      "(%P)", _
    RegexOptions.IgnoreCase _
    Or RegexOptions.CultureInvariant _
    Or RegexOptions.IgnorePatternWhitespace _
    Or RegexOptions.Compiled _
    )
Public Dim regexReplace As String = _
      "percentP"

Dim result As String = regex.Replace(InputText,regexReplace)

Have a look at Expresso [^]- creates, examines and explains regex strings. And it's free.

Solution 2

While Griff's solution is appropriate, I'm not a big fan of Regex, so I would approach it this way:

myString = myString.Replace("%P", replacementString);

That's a LOT less code, a LOT faster than Regex will ever be, and consumes fewer resources besides.
