Package.CreatePart Method (Uri, String)

Creates a new uncompressed part with a given URI and content type.

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

public PackagePart CreatePart(
	Uri partUri,
	string contentType
)

Parameters

partUri
Type: System.Uri
The uniform resource identifier (URI) of the new part.
contentType
Type: System.String
The content type of the data stream.

Return Value

Type: System.IO.Packaging.PackagePart
The new created part.

ExceptionCondition
ArgumentNullException

partUri or contentType is null.

ArgumentException

partUri is not a valid PackagePart URI.

InvalidOperationException

A part with the specified partUri is already present in the package.

ObjectDisposedException

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

IOException

The package is read-only (a new part cannot be added).

CreatePart initializes an empty Stream for the new part. The PackagePart.GetStream method can be used to obtain a reference to the stream instance associated with the part.

The part CompressionOption is CompressionOption.NotCompressed.

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 Inheritors

CreatePart internally calls the derived class's CreatePartCore method to actually create the part based on the physical format implemented in the derived class.

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.
