Package.Flush Method

Saves the contents of all parts and relationships that are contained in the package.

Namespace:  System.IO.Packaging
Assembly:  WindowsBase (in WindowsBase.dll)

public void Flush()

ExceptionCondition
ObjectDisposedException

The package is not open (Dispose or Close has been called).

IOException

The package is read-only and cannot be modified.

Flush internally calls the derived class's FlushCore implemetation to perform the actual format-specific flush operation. The derived class's FlushCore method is responsible for actually saving the part and relationship content to the specific physical derived class implementation.

By default, a ZipPackage derived implementation of the abstract Package base class is provided and used. In the default operation, Flush internally calls FlushCore to save the parts and relationships in a ZIP file package.

Flush is called automatically by the Close and Dispose methods. When Close or Dispose is called you do not have to call Flush separately.

Notes to Inheritors

Flush internally calls the derived class's FlushCore method to actually flush the part based on the physical format implemented in the derived class.
