Flush Method

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()
You cannot use methods in XAML.


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


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.
