Set custom document properties with Word interop

Question

I want to set some custom document properties of a word document I\'m creating in my C# code. To do this, I followed this MSDN article and came up with this code:

Answer 1

After asking the question in the MSDN forums, the answer was brought up. The problem is, that the way I tried was specific to VSTO. Due to my unknowing, I mixed up VSTO, Interop and other definitions, thus tagging this question wrong.

It now works using the following code:

logger.Info("Setting document properties");
object properties = doc.CustomDocumentProperties;
Type propertiesType = properties.GetType();

object[] documentCodeProperty = { "Codice_documento", false, Core.MsoDocProperties.msoPropertyTypeString, args[3] };
object[] documentVersionPoperty = { "Versione_documento", false, Core.MsoDocProperties.msoPropertyTypeString, args[4] };

propertiesType.InvokeMember("Add", BindingFlags.InvokeMethod, null, properties, documentCodeProperty);
propertiesType.InvokeMember("Add", BindingFlags.InvokeMethod, null, properties, documentVersionPoperty);
