Примеры

В следующем примере показано, как создать новую PackagePart и сохранить данные в части.

// 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.

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

' Copy the data to the Document Part
Using fileStream As New FileStream(documentPath, FileMode.Open, FileAccess.Read)
    CopyStream(fileStream, packagePartDocument.GetStream())
End Using ' end:using(fileStream) - Close and dispose fileStream.
