For additional information about package parts see section 1.1 in the Open Packaging Conventions (OPC) specification available for download at http://go.microsoft.com/fwlink/?LinkID=71255.

Notes to Implementers: CreatePart internally calls the derived class CreatePartCore method to actually create the part based on the physical format implemented in the subclass.

The following example shows how to create a new PackagePart and then store data into the part. For the complete sample, see Writing a Package Sample.

// Add the Document part to the Package
PackagePart packagePartDocument =
    package.CreatePart(partUriDocument,
                   System.Net.Mime.MediaTypeNames.Text.Xml);

// Copy the data to the Document Part
using (FileStream fileStream = new FileStream(
       documentPath, FileMode.Open, FileAccess.Read))
{
    CopyStream(fileStream, packagePartDocument.GetStream());
}// end:using(fileStream) - Close and dispose fileStream.
