SetIntValue Method
See Also  Example
Leadtools.Dicom Namespace > DicomDataSet Class : SetIntValue Method




Sets the integer value(s) of a Data Element.

Overload List

OverloadDescription
SetIntValue(DicomElement,IntPtr,Int32) Sets the integer value(s) of a Data Element.  
SetIntValue(DicomElement,Int32[],Int32) Sets the integer value(s) of a Data Element.  

Example

This example will initialize a DICOM Dataset and then insert different types of elements, update their values and finally verify those values by reading them back from the Dataset.

Remarks

Note: The user is responsible to allocate the memory for value.

If you want to set more than one value in the Value Field of the Data Element, put all the integer values in an array of integer values, set value to the address of the array, and set count to the corresponding number of entries. For example, if you wish to set three integer values in the Value Field of the Data Element, create an array of integer values containing the three integer values, set value to the address of the array, and set count to three.

If more than one value is stored in the Value Field of the Data Element, you must set all values at the same time.

This method can be called only if the Value Representation of the Data Element is DicomVRType.AT, DicomVRType.IS, DicomVRType.SL, or DicomVRType.UL. For more information about Value Representations, refer to Default Value Representation Table.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
