Percent-decoding a URL

Board-up his cube.

At first I thought he was smart to use Excel to generate code using ="strNew.Replace(""%" & DEC2HEX(A1) & """, """ & CHAR(A1) & """);" to save typing of boring code that anybody can type. :) But then I noticed case sensitive replacements that as possible to generate using following VB.NET code:

For i As Integer = 32 To 126
Dim ch As Char = Chr(i)
If Not Char.IsLetterOrDigit(ch) Then
Console.WriteLine("strNew.Replace(""%{0:X2}"", ""{1}"");", i, ch)
If i Mod 16 > 9 Then
Console.WriteLine("strNew.Replace(""%{0:x2}"", ""{1}"");", i, ch)
End If
End If
Next i

It's still less typing than traditional way to do stuff. Genius! :cool:

Your coworker is a genius. strNew.Replace("%7E", "~"); ... strNew.Replace("%7e", "~"); This one adds another wtf to the thing. You should probably send to to the dailywtf.com.

Apart from the fact that it's a horror code, it will just won't work as he needs to assign value returned by Replace to strnew strNew = strNew.Replace("%20", " ");

If the code was written on C++ strNew might be a CString, if it was written on C# it might be StringBuilder.

any regex alternatives by your co-worker? that might be really interesting... :laugh:

Assuming strNew is of a type that allows replace to be used upon it in that fashion, would its treatment of "%253F" match any known standard?

[ClementsDan]

"%253F" → "%3F" → "?". I don't know of any standard that encodes a question mark that way.

[ClementsDan]

Right. It's a CString.

[Luc Pattyn]

This minor mistake is easily fixed by moving the %25 -> % replacement to the bottom of the magnificent method. :)

Your co-worker definitely needs the vacation. Months of rest and medication may help them out. :)

not if its a StringBuilder
