Generics documentation - C# / C Sharp

samuelhon

Hi

I've been looking at NetTiers and came across this line:

public static Entity LocateOrCreate<Entity>(string key, string
typeString, Type entityFactoryType) where Entity : class, IEntity,
new()

Just wondered if anyone could point me towards some good documentation
on generics?

Thanks

Sam

For your example, the Entity is a generic type, and it has three
constraints:

1It has to be a class.
2It has to implement IEntity
3The new constraint, which specifies that any type argument in a
generic class declaration must have a public parameterless constructor.
