[ExtensionAttribute()]
public static List<Difference> Compare( 
   DicomDataSet dataset,
   DicomDataSet compareTo
)

'Declaration

<ExtensionAttribute()>
Public Shared Function Compare( _
   ByVal dataset As DicomDataSet, _
   ByVal compareTo As DicomDataSet _
) As List(Of Difference)

'Usage

Dim dataset As DicomDataSet
Dim compareTo As DicomDataSet
Dim value As List(Of Difference)
 
value = CompareExtensions.Compare(dataset, compareTo)

[ExtensionAttribute()]
public:
static List<Difference^>^ Compare( 
   DicomDataSet^ dataset,
   DicomDataSet^ compareTo
)

Parameters

dataset: The original DICOM dataset.
compareTo: The DICOM dataset to compare to.

Return Value

A list of tag differences between the DICOM datasets.

This example compares two datasets with different patient IDs.
