Is there an enum in System or System.Core that has all the ComparisonOperators?
I just wrote the following enum, but it seems like a common enough thing that one might already exist.
public enum ComparisonPredicate
I found one in System.Web.UI, but it would be more than silly to introduce a dependency for that http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.validationcompareoperator(v=VS.100).aspx
Also, I already looked at
ExpressionType, but I don't want something with that broad of a scope
AFIK such a thing does not exist. You are probably better off using your own, for now.
A bit late, but .Net 3.5 introduced the
ExpressionType enumeration in
System.Linq.Expressions, see http://msdn.microsoft.com/en-us/library/bb361179(v=vs.110).aspx for more details.
