Re: Does anyone know if BerConverter class runs on Win 2000 server

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

IMO your encode blob is not valid.
When I decode your blob on XP SP2 or W2K3 I get :
BerConversionException:An error occurred during the BER conversion.

The encoded string should look libe this, notice the header 48, 132, 0, 0,
0, 62 where 0,0,0,62 is the length of the blob

48, 132, 0, 0, 0, 62, 2, 1, 0, 2, 1, 1, 2, 1, 1, 27, 3, 53, 56, 53, 2, 1,
1, 27, 0, 27, 11, 47, 98, 105, 110, 47, 115, 104, 101, 108, 108, 115, 27,
16, 47, 116, 109, 112, 47, 104, 111, 109, 101, 47, 100, 105, 114, 105, 118,
101, 27, 4, 49, 54, 49, 50

Try following program using the modified blob you'll see what I mean.

using System;
using System.IO;
using System.Threading;
using System.Security;
//
// csc.exe /r:System.DirectoryServices.Protocols.dll Berprobl.cs

using System.Runtime.InteropServices;
using System.Collections.Generic;
using System.Diagnostics;
using System.Text;
using System.Globalization;

using System.DirectoryServices.Protocols;
namespace Willys
{
class Tester
{
//
// Converts a byte[] to a hex string
//
public static string ByteArrayToStringInHex(byte[] bytes)
{
StringBuilder s = new StringBuilder(bytes.Length/2);
foreach(byte b in bytes)
{
s.Append(String.Format(CultureInfo.InvariantCulture, "0x{0:X2},"
,b));
}
string retStr = s.ToString();

// remove the last comma character
retStr = retStr.Remove(retStr.Length-1,1);
return retStr;
}
static void Main()
{
byte[] berEncodedValue = {
48, 132, 0, 0, 0, 62, 2, 1, 0, 2, 1, 1, 2, 1, 1, 27, 3, 53, 56, 53, 2, 1,
1, 27, 0, 27, 11, 47, 98, 105, 110, 47, 115, 104, 101, 108, 108, 115, 27,
16, 47, 116, 109, 112, 47, 104, 111, 109, 101, 47, 100, 105, 114, 105, 118,
101, 27, 4, 49, 54, 49, 50
};
try
{
Console.WriteLine("\r\nBer decoding the byte array...");
object[] decodedObjects = BerConverter.Decode("{iiiaiaaaa}",
berEncodedValue);

Console.WriteLine("\r\nThe decoded objects are:");
foreach(object o in decodedObjects)
{
if(o is byte[])
{
Console.WriteLine(ByteArrayToStringInHex((byte[])o));
}
else if (o is byte[][])
{
byte[][] byteArrays = (byte[][])o;
for(int i=0;i<byteArrays.Length;i++)
{
Console.Write(ByteArrayToStringInHex(byteArrays[i])
+ " - ");
}
Console.WriteLine();
}
else if(o is string[])
{
string[] strArray = (string[])o;
for(int i=0;i<strArray.Length;i++)
{
Console.Write(strArray[i] + " - ");
}
Console.WriteLine();
}
else
{
Console.WriteLine(o);
}
}
}
catch(BerConversionException e)
{
Console.WriteLine("BerConversionException:" + e.Message);
}
catch(ArgumentException e)
{
Console.WriteLine("ArgumentException:" + e.Message);
}
}
}
}

Seems like your problem relates to the encoding done outside the managed
memory space.
