Document metadata using spfile

Question

Hi

i want to add a metadata property for all the documents uploaded in a document library, so that if any user downloads the document, by looking at the document properties  he will be sure that document is uploaded in portal. The documents can be word,excel,pdf etc..

i tried using the following method  

file.AddProperty("Test Property", "Vinay"); But this is not working..Please let me know if there is anyway i can Add/modify Metadata of a document.

Regards,

Vinay

You should use the SetProperty method of the SPFile class:

public static void UpdateFileMetadata()
{
            using (SPSite site = new SPSite("http://basesmc2008"))
            {
                using (SPWeb web = site.OpenWeb())
                {
                    SPFile file = web.GetFile("http://basesmc2008/tester/refinement.xml");
                    file.SetProperty("mykey","great");
                    file.Update();
                }
            }
}

Hi Steve

I tried the above procedure, but i still don't see any additional properties to the document. Will the above method applies to all type of documents?

This works in my environment. Are you doing this in an event handler? If you are trying to set properties that are included in the built-in properties of a Microsoft Office file these may get over written when the file is updated.
