C# Passing a class type as a parameter

Question

This for C#? Passing Class type as a parameter

I have a class adapter that implements an Interface. I want to fill an array structure with MyFooClass instances where MyFooClass's name or reference I want to receive it from outside. I'll instantiate them inside my adapter code.

For example:

    public void FillWsvcStructs(DataSet ds, ClassType Baz)
    {
        IFoo.Request = ds.DataTable[0].Request;
        IFoo.Modulebq = string.Empty;
        IFoo.Clasific = string.Empty;
        IFoo.Asignadoa = ds.DataTable[0].Referer;
        IFoo.Solicita = "Jean Paul Goitier";


        // Go with sub-Elems (Also "Interfaceated")
        foreach (DataSet.DataTableRow ar in ds.DataTable[1])
        {
            if ((int) ar.StatusOT != (int)Props.StatusOT.NotOT)
            {
                ///From HERE!
                IElemRequest req = new (Baz)(); // I don't know how to do it here
                ///To HERE!

                req.Id = string.Empty;
                req.Type = string.Empty;
                req.Num = string.Empty;
                req.Message = string.Empty;
                req.Trkorr = ar[1];
                TRequest.Add(req);
            }
        }
    }

Generics and their constraints should do what you want, I believe:

public void FillWsvcStructs<ClassType>(DataSet ds) where ClassType : IElemRequest, new()
{
    IFoo.Request = ds.DataTable[0].Request;
    IFoo.Modulebq = string.Empty;
    IFoo.Clasific = string.Empty;
    IFoo.Asignadoa = ds.DataTable[0].Referer;
    IFoo.Solicita = "Jean Paul Goitier";


    // Go with sub-Elems (Also "Interfaceated")
    foreach (DataSet.DataTableRow ar in ds.DataTable[1])
    {
        if ((int) ar.StatusOT != (int)Props.StatusOT.NotOT)
        {
            IElemRequest req = new ClassType();

            req.Id = string.Empty;
            req.Type = string.Empty;
            req.Num = string.Empty;
            req.Message = string.Empty;
            req.Trkorr = ar[1];
            TRequest.Add(req);
        }
    }
}
