I have a class (A web control) that has a property of type IEnumerable and would like to work with the parameter using LINQ.

Is there any way to cast / convert / inv

    This is years later, but I solved the List problem.

    void Method(IEnumerable source)
{
    var enumerator = source.GetEnumerator();
    if (enumerator.MoveNext())
    {
        MethodInfo method = typeof(MyClass).GetMethod("Method2");
        MethodInfo generic;
        Type type = enumerator.Current.GetType();
        bool sameType = true;

        while (enumerator.MoveNext())
        {
            if (enumerator.Current.GetType() != type)
            {
                sameType = false;
                break;
            }
        }

        if (sameType)
            generic = method.MakeGenericMethod(type);
        else
            generic = method.MakeGenericMethod(typeof(object));

        generic.Invoke(this, new object[] { source });
    }
}
