Finds or inserts (if not found) an element in the data set and sets the value of the element.
public DicomDataSet InsertElementAndSetValue(
DicomElement element,
bool tree,
long tag,
DicomVRType vrType,
object value
)
public:
DicomDataSet^ InsertElementAndSetValue(
DicomElement^ element,
bool tree,
Int64 tag,
DicomVRType^ vrType,
Object^ value
)
element
An item in the data set.
tree
true to evaluate the Data Set as a tree; false to evaluate the Data Set as a list.
tag
Tag of the item to find or insert.
vrType value representation or format type (character string, integer, person name, etc.) of the element to be inserted.
value
value to insert.
A reference to the DicomDataSet class (a 'this' pointer).
This method is used to set the value of an existing DICOM data set element, or if the existing element does not already exist, to insert the element and then set its value.
If the element is being inserted (does not already exist), then this overload allows you to specify the value representation DicomVRType of the element to be inserted.
For example, DicomTag.CurveData can have a value representation of either DicomVRType.OB or DicomVRType.OW, so this overload allows you to specify the DicomVRType:
The value parameter can be any supported DICOM value. For details on the value parameter, see SetValue.
This method returns a reference to the DicomDataSet class so that it can be used as part of a fluent interface. After calling this method, the InsertElementAndSetValueResult property contains a value that indicates the success of the method. For an example of how this can be used efficiently to create a DICOM sequence, see BeginEditSequence.
