Hello cable beach,

1.
>> So how can I do this?
>> C# Code:
>> public Void Init(object obj)
>> {
>> string location = obj.Location; // Somehow, without any external references.
>> }

1.1 Unfortunately, this syntax style (indicating a dynamic call to the Location property of a late-bound object) is not possible in C#.

1.2 To make a late bound call to an imported COM object's method or property, you must use the static Type.InvokeMember() function.

1.3 Here are links to 2 useful short articles explaining this :

Calling a COM Component From C# (Late Binding)
http://www.c-sharpcorner.com/UploadFile/psingh/CallingCOMComponentFromCSharp12022005231615PM/CallingCOMComponentFromCSharp.aspx[^]

Late Binding with Reflection
http://www.c-sharpcorner.com/UploadFile/samhaidar/LateBindingWithReflection09122005053810AM/LateBindingWithReflection.aspx[^]



2.

>> VB.net code (this works):
>> public Sub Init(obj as Object)
>> dim location as string = obj.Location
>> End Sub

2.1 Although I do not know enough about VB.NET, I am not surprised that the above syntactic expression is possible. It is likely designed to be so since this is definitely possible in VB6.0.


2.2 I believe that the restriction in C# is probably due to strict type checking which is enforced in languages like C++.
