C# Interface Require Constructor at Andrew Lennon blog

C# Interface Require Constructor. Defining a constructor on an interface is not allowed in any programming language that i know of, definitely not in c#. Interface isomething { void fillwithdatarow(datarow) }. The technical answer is that you can't; The type constraint new () allows you to get an instance (object) of a generic type t in a generic class. I need to create an interface that specifies that the constructor for any implementing class has to take specific arguments. I know that you can't have a constructor in an interface, but here is what i want to do: Having lots of interface that needs to pass in a constructor looks messy, is there any neat way of doing it? In addition, you must use an interface if you want to simulate inheritance for structs, because they can't actually inherit from another. One way to force some sort of constructor is to declare only getters in interface, which could then mean that the implementing class must have a. This text, called a constructor constraint, requires the type argument corresponding to the constrained type parameter to have a public or internal default.
