Type.GUID Replacement
in [Compact Framework]
|
From: MarkusSchaber on 24 Dec 2009 03:21 Hello, How do I get the Guid for a class in the compact framework (the one that was defined with the GuidAttribute from System.Runtime.InteropServices)? Or is there an alternate way (possibly compatible with the desktop framework) to add a GUID to a compact framework type? Thanks, Markus

From: Peter Foot on 1 Jan 2010 18:00 Assuming the Type is a COM Interface/Class wrapper it will have been give a GuidAttribute so the following will work:- Guid typeGuid = Guid.Empty; Type interfaceType = myObject.GetType().GetInterfaces()[0]; object[] attributes = interfaceType.GetCustomAttributes(false); foreach(object o in attributes) { if(o is GuidAttribute) { //has GuidAttribute - get the value GuidAttribute ga = (GuidAttribute)o; typeGuid = new Guid(ga.Value); } } For simplicity the code here only gets the first implemented interface so you may need to change this code depending on how you are getting the object/type in the first place but you can see the logic to get the Guid - look through the custom attributes of the type and if you find a GuidAttribute get its value (which will be a guid as a string) and create a new Guid object from it.

In my case, we assign the GUID directly to a class (it's not for COM purposes), but I'll try whether it works this way... Thanks, Markus |
