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 M

You need a generic:

public void FillWsvcStructs(DataSet ds) where TBaz : IElementRequest, new()
{
    // ...
    IElementRequest req = new TBaz();
    // ...
}

The generic constraint ("where...") enforces that the type you pass in implements the IElementRequest interface and that it has a parameter-less constructor.

Assuming you had a class Baz similar to this:

public class Baz : IElementRequest
{
    public Baz()
    {
    }
}

You would invoke this method like so:

DataSet ds = new DataSet();
FillWsvcStructs(ds);

Addendum

Multiple, different, generic type parameters can each have there own type constraint:

public void FillWsvcStructs(DataSet ds) 
    where TFoo : IFoo, new()
    where TBar : IBar, new()
    where TBaz : IElementRequest, new()
{
    // ...
    IFoo foo = new TFoo();
    IBar bar = new TBar();
    IElementRequest req = new TBaz();
    // ...
}
