Summary

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

Syntax

Java

WinRT C#

C++

public bool SetStringValue( 
   DicomElement element, 
   string value, 
   DicomCharacterSetType characterSet 
)

Public Overloads Function SetStringValue( _ 
   ByVal element As Leadtools.Dicom.DicomElement, _ 
   ByVal value As String, _ 
   ByVal characterSet As Leadtools.Dicom.DicomCharacterSetType _ 
) As Boolean

public bool SetStringValue(  
   Leadtools.Dicom.DicomElement element, 
   string value, 
   Leadtools.Dicom.DicomCharacterSetType characterSet 
)

public boolean setStringValue(DicomElement element, String value)

 function Leadtools.Dicom.DicomDataSet.SetStringValue(DicomElement,String,DicomCharacterSetType)(  
   element , 
   value , 
   characterSet  
)

public: 
bool SetStringValue(  
   Leadtools.Dicom.DicomElement^ element, 
   String^ value, 
   Leadtools.Dicom.DicomCharacterSetType characterSet 
)

Parameters

element
An item in the Data Set.

value
Character string that contains the string value to set.

characterSet
Character set to use when inserting the input string.

Return Value

true if the string value(s) were set successfully. false if could not set the string value(s) of the Data Element.

Remarks

This method can be called only if the Value Representation of the Data Element is:

For more information about Value Representations, refer to Default Value Representation Table.

Example

This example shows how to use the various overloads of SetStringValue and SetStringValuePtr to write a japanese string as the value of a DICOM element in a DicomDataSet
