Generic class with restricted Type parameter

Question

I want to create a generic class that takes a type parameter and restrict that parameter to numeric types or more generally to any type upon which the increment operator ++ can be applied.

I know I can do the following to restrict to structs but obviously there are structs that aren't numeric types and for which the ++ operator is not supported. Can I do this in C#

class Example<T> where T : struct
{
  //Implementation detail
}

Answer 1

Unfortunately this is not possible (see here.) You can only constrain the type to:

• Implement a specific interface or derive from a specific class
• Be a class or struct
• Have a parameterless constructor

Constraining types to have specific operators is a much-requested feature but I believe it will not be in C# 4 either.
