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 { Equal, Unequal, LessThan, LessThanOrEqualTo, GreaterThan, GreaterThanOrEqualTo }
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
The enum keyword in C# and . NET is used to declare an enumeration, a distinct type that consists of a set of named constants called the enumerator list. Usually, an enum is declared as public within a namespace and is available to all classes in the namespace.
There are four types of operators that can be used in expressions: comparison.
A comparison operator compares two values and returns a boolean value, either True or False . Python has six comparison operators: less than ( < ), less than or equal to ( <= ), greater than ( > ), greater than or equal to ( >= ), equal to ( == ), and not equal to ( != ).
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.
AFIK such a thing does not exist. You are probably better off using your own, for now.
