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

    Does your Method2 really care what type it gets? If not, you could just call Cast():

    void Method (IEnumerable source)
{
    Method2(source.Cast());
}



    If you definitely need to get the right type, you'll need to use reflection.
    


    Something like:
    


    MethodInfo method = typeof(MyType).GetMethod("Method2");
MethodInfo generic = method.MakeGenericMethod(type);
generic.Invoke(this, new object[] {source});

    


    It's not ideal though... in particular, if source isn't exactly an IEnumerable then the invocation will fail. For instance, if the first element happens to be a string, but source is a List, you'll have problems.
