BulkDataUuid Property

Summary

Gets or sets the bulk data UUID that is about to be written.

Syntax

C++

public string BulkDataUuid { get; set; }

Public Property BulkDataUuid As String

public: 
property String^ BulkDataUuid { 
   String^ get(); 
   void set (    String^ ); 
}

Property Value

The bulk data UUID that is about to be written.

Remarks

If DicomDataSetSaveXmlFlags.BulkDataUuid is passed to SaveXml, a dummy UUID is generated for each binary data element that is about to be written, and is returned in BulkDataUuid. This can be changed to a custom UUID by setting the BulkDataUuid to the desired UUID.

Example

This example will load a sample DICOM data set, then save it in the Native DICOM Model XML format specified in PS3.19.A.1 of the DICOM specification, changing each BulkData uuid attribute to a custom UUID.
