GetValue<T>(DicomElement,T) Method

Summary

Returns the value of a DICOM element

Syntax

C++

public T GetValue<T>(  
   Leadtools.Dicom.DicomElement element, 
   T defaultValue 
)

Public Overloads Function GetValue(Of T)( _ 
   ByVal element As Leadtools.Dicom.DicomElement, _ 
   ByVal defaultValue As T _ 
) As T

public: 
T^ GetValuegeneric<typename T> 
(  
   Leadtools.Dicom.DicomElement^ element, 
   T^ defaultValue 
)

Parameters

element
an item in the data set

defaultValue
a value of type T that is returned if the actual value cannot be retrieved.

Type Parameters

T
specifies the type of the value to return

Return Value

a value of type T that is the value of the DICOM element

Remarks

For information on this method, see GetValue.

Example

This example will insert several elements into a DICOM data set, and then retrieve the values
