Re: Assignment of a unique ID to an OpenXML file

I have recently got an intern project. In this task, I must assign unique IDs to OpenXML files used by Microsoft Office 2010. I have so far attempted a lot of ways of doing it. But all failed. I use visual studio 2010. Do you have any idea what methods and classes I have to use to assign a unique ID to a file with C#? If you give me any example with C# code, I would appreciate it.

This isn't quite clear to me. Are you having difficulty creating the unique ID or having trouble storing it in the OpenXML file? You can generate a unique ID as a GUID:

Guid id;
id = Guid.NewGuid();

Storing the value could be done simply by changing the file name, but if you need to embed the ID, you could use a CustomXmlPart. The code for adding this part is different for each type of document. There is a simple example showing how to set the content of that part for a wordprocessing document here.

I hope that helps.

Thanks. It helps me how to add something to an xml document. I will try it and ask you another question.

I found an example of xsd:ID on the net.

n

<xsd:simpleType name="ID" id="ID">

<xsd:restriction base="xsd:NCName"/>

</xsd:simpleType>

they say this code is a general synopsis. Whatever.. Do you how to add a string value to this formula? and Can I use it for MS OFFICE 2010 xml files?
