SetValue Method

Summary

Sets the value(s) of a Data Element. The value can be any supported type.

Syntax

C++

public bool SetValue( 
   DicomElement element, 
   object value 
)

Public Function SetValue( _ 
   ByVal element As DicomElement, _ 
   ByVal value As Object _ 
) As Boolean

public: 
bool SetValue(  
   DicomElement^ element, 
   Object^ value 
)

Parameters

element
An item in the Data Set.

value

An Object that can be any supported type, or an array of any supported type.

Return Value

true if the object value was set successfully. false if could not set the object value of the Data Element.

Remarks

Note: The user is responsible to allocate the memory for value. This is very flexible function that can be used to set the value of almost any DICOM data element, regardless of the DicomVRType The Object can be any of the following:

String
Byte
DateTime
DicomDateValue
DicomTimeValue
DicomDateTimeValue
Int32
Int16
Double
Single
an array of any of the above types

Example

This example shows how to set the value of various DICOM elements, regardless of the regardless of the DicomVRType or the multiplicity.
