Antonio,
In addition to the other comments:
then '@@', etc...Ascii codes for '?' and '@' are greater than '<' '=' '>'.
Remember .NET stores strings in Unicode, specifically UTF-16. UTF-16 means that the Unicode characters (which can be upto 32-bits) are stored as 16 bit values.
This is an excellent article on the perils & pitfalls of comparing strings in .NET 2.0:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/StringsinNET20.asp
By default strings are compared via the CurrentCulture. It sounds like you are expecting the strings to be compared via ASCII Ordinal, not even Unicode Ordinal.

Hello. I have tried to insert this items into a SortedList.
dic = New SortedList
dic.Add("<<", "<<")
dic.Add("==", "==")
dic.Add(">>", ">>")
dic.Add("@@", "@@")
dic.Add("??", "??")
Debugging this peace of code I have notice that '??' appears as first item, then '@@', etc...Ascii codes for '?' and '@' are greater than '<' '=' '>'. May be this is a bug or an undocumented behavior ??
TIA
Antonio
