GetValueDelegate Delegate

Summary

A delegate used with some overloads of GetValue<T> to get a value of an element

Syntax

C#
VB
C++
public delegate object GetValueDelegate( 
   string value 
) 
Public Delegate Function GetValueDelegate( _ 
   ByVal value As String _ 
) As Object 
public delegate Object^ GetValueDelegate(  
   String^ value 
)

Parameters

value
a string representation of the DICOM element value that is to be converted

Return Value

An Object of the desired type.

Remarks

This delegate is used with certain overloads of GetValue<T>.

The delegate takes a string as input, and converts it into any desired class type. It is used with the GetValue<T> that take GetValueDelegate parameter.

Example

This example will retrieve a value from a data set as a PersonName type using a delegate
