CaseInsensitiveHashCodeProvider
When this object is passed
to a
Hashtable constructor, it overrides the
GetHashCode( ) method to allow string comparison
without regard to case. If you pass an instance of this type into the
Hashtable constructor, you should also pass in an
instance of CaseInsensitiveComparer to ensure that
any comparison operations (such as sorting) are also performed in a
case-insensitive fashion. You can obtain a standard provider that
uses the System.Globalization.InvariantCulture
rules for generating hashcodes by using the
CaseInsensitiveComparer instance returned from the
static DefaultInvariant property.
public class CaseInsensitiveHashCodeProvider : IHashCodeProvider { // Public Constructors public CaseInsensitiveHashCodeProvider( ); public CaseInsensitiveHashCodeProvider(System.Globalization.CultureInfoculture); // Public Static Properties public static CaseInsensitiveHashCodeProvider Default{get; } public static CaseInsensitiveHashCodeProvider DefaultInvariant{get; } // Public Instance Methods public int GetHashCode(objectobj); // implements IHashCodeProvider }
