.NET library, containing extension methods for String, StringBuilder and ReadOnlySpan<Char>.


  • Extension methods which return an equal (and therefore persistable) Int32 hashcode for an identical Char sequence everytime they are called - even on String, StringBuilder or ReadOnlySpan<Char>. The hashcodes can be specified to hash the sequence ordinal, ordinal case insensitive or alphanumeric case insensitive. The hashcodes produced by this library are not equivalent to the hashcodes produced by the .NET-Framework 4.0 System.String class, because they use roundshifting to keep more information. Don't use these hashcodes for security critical purposes (such as hashing passwords)!

       // Different HashTypes may produce different hashcodes on the same Char sequence
       // and must therefore not be mixed:

Adds support for Netstandard 2.0 and .NET-Framework 4.5.
     The extension method GetStableHashCode is now available also on ReadOnlySpan<char> on all supported platforms except .NET Framework 4.0.

     The enum value HashType.AlphaNumericNoCase is now marked as obsolete and has a replacement in HashType.AlphaNumericIgnoreCase.
