Server.URLEncod e diffrences in asp and vb.net

[Mark_Rarefy]

Trying to urlencode this string:

Â�»Ã�Ã�Å’Å*Ëœ ªŒÂ�›h^aYh

in vb.net (using either HttpUtility.Url Encode(strEncry pted, encoding.UTF8)
orServer.UrlEnc ode) I get:
%c2%90%c2%bb%c3 %81%c3%8f%7f%c5 %92%c5%a0%cb%9c %c2%aa%c5%92%c2 %9d%e2%80%bah%5 eaYh

in ASP script (using Server.URLEncod e) I get:
%90%BB%C1%CF%7F %8C%8A%98%AA%8C %9D%9Bh%5EaYh

Any idea why?

Thanks,
Mark

Well, This ended up working:
System.Text.Enc oding.UTF8.GetS tring(Convert.F romBase64String (strEncrypted))

Still odd that you have to jump though those hoops to get it to do what ASP
does.

Any insight would be appreciated.

Thanks,
Mark

Hello Mark,

Trying to urlencode this string:

Hm... ;-)

Any idea why?

ASP uses a different character encoding -- that's not UTF-8, but some 8 bit
encoding like ISO Latin 1 or Windos-1252.

Spoke to soon on that. Was looking at the result of the other page. I did
find a long right up that seems to be on the right track.

Thanks for the reply.

When I tell ASP to force encoding as so:
Session.CodePag e = 65001
Response.CharSe t = "utf-8"

I get a totally diffrent result then the previous 2

I looked for the two encoding methods you mentioned in System.Text.Enc oding
but don't see them as options. I will google them and see what I can find.

That did the trick. I couldn't find anything to do the conversion so I
wipped up this:
Public Function ASPURLEncode(By Val StringToEncode As String) As String

Dim TempAns As New StringBuilder
Dim CurChr As Integer = 1
Do Until CurChr - 1 = Len(StringToEnc ode)
Select Case Asc(Mid(StringT oEncode, CurChr, 1))
Case 48 To 57, 65 To 90, 97 To 122
TempAns.Append( Mid(StringToEnc ode, CurChr, 1))
Case 32
TempAns.Append( "%" & Hex(32))
Case Else
TempAns.Append( "%")
TempAns.Append( Hex(Asc(Mid(Str ingToEncode, CurChr, 1))))
End Select
CurChr = CurChr + 1
Loop
ASPURLEncode = TempAns.ToStrin g
End Function

And now I have a match.

Thanks for your help.

I'm no old school ASP guy, but I'd guess that none of these properties affect
URL encoding performed by ASP.
I looked for the two encoding methods you mentioned in
System.Text.Enc oding but don't see them as options. I will google
them and see what I can find.

In ASP.NET, you can use System.Web.Http Utility.UrlEnco de(String, Encoding)
to URL encode a string using any System.Text.Enc oding.

I wrote that function but if I can, I would rather do it within the framework
..

"ISO Latin 1" isn't an option in system.text.enc oding.

Is there some other encoding method in the framework?

Thanks,
Mark

ISO Latin 1 is an alias for ISO-8859-1. You can create an instance either
by name

Encoding latin1 = Encoding.GetEnc oding("ISO-8859-1");

or by its Windows code page number

Encoding latin1 = Encoding.GetEnc oding(28591);

Hello Joerg,

Awesome, Windows-1252 did the trick.

Thanks for your help,
