How to change file in sharepoint library?

Question

I have sharepoint documents library and I have wcf service from where i should download new version of document file on button click.

So i got next method:

   public void UpdateFile(SPListItem item, Stream newFileStream)
    {
       // How to update file?
    }

And i want to change existing sp item file to new one from stream.

How to do this?

Answer 1

as per my knowledge you have to upload a template document with content type and metadata mapping.

so u can update the document. because document is generated based on your template.
