c# - How to define generic class for mapping muti-class?

Question

public class UnityTool<IClass,cbClass>  where IClass, cbClass:class
{
    public static void UnityTest()
    {
        IUnityContainer container = new UnityContainer();

        container.RegisterType<IClass, cbClass>();        
    }
}

I'd like to create a common static method to implement the DI(Dependency Injection). but vs2013 told me that my grammer is wrong. how to solve it?

Answer 1

This is correct syntax (separate the where restriction):

public class UnityTool<IClass,cbClass>
          where IClass:class
          where cbClass:class
{
    public static void UnityTest()
    {
        IUnityContainer container = new UnityContainer();

        container.RegisterType<IClass, cbClass>();        
    }
}
