This interface implements a custom hash function to supply a hashcode to an object. Normally hashtables use System.Object.GetHashCode( ) for hash keys. However, if a Hashtable is constructed using an object that implements this interface, GetHashCode( ) can be used to provide a customized hash function. CaseInsensitiveHashCodeProvider is an example of a custom hash function.

public interface IHashCodeProvider {
// Public Instance Methods
   public int GetHashCode(object obj);
}
