.NET Forum / .NET Framework / New Users / March 2006Class constraints
Hello, i can use this chunk of code to constraint type T only to value types: public class Test<T> where T : struct {...} Is there a possibility to constraint type T only to number types (int, float, decimal, etc.)? Thanks > i can use this chunk of code to constraint type T only to value types: > public class Test<T> where T : struct {...} > Is there a possibility to constraint type T only to number types (int, > float, decimal, etc.)? No - there's nothing which particularly denotes numeric types.  SignatureJon Skeet - <skeet@pobox.com> http://www.pobox.com/~skeet Blog: http://www.msmvps.com/jon.skeet If replying to the group, please do not mail me too Unfortunately dotNet doesn't have CLU's constraining clauses which require the allowed T classes have certain methods or properties. You could mimic this at runtime in the constructor by using reflection, but it's not a compile time feature.
