Class HashCodeCombiner

Used to create a .NET HashCode from multiple objects.

Inheritance

System.Object

Namespace: Umbraco.Cms.Core

Assembly: Umbraco.Core.dll

Syntax

public class HashCodeCombiner

Remarks

.Net has a class the same as this: System.Web.Util.HashCodeCombiner and of course it works for all sorts of things which we've not included here as we just need a quick easy class for this in order to create a unique hash of directories/files to see if they have changed. NOTE: It's probably best to not relying on the hashing result across AppDomains! If you need a constant/reliable hash value between AppDomains use SHA1. This is perfect for hashing things in a very fast way for a single AppDomain.
