public:T^ GetValuegeneric<typename T>(DicomElement^ element,T^ defaultValue,GetValueDelegate^ getValueDelegate)
element
an item in the data set
defaultValue
a value of type T that is returned if the actual value cannot be retrieved.
getValueDelegate
an optional delegate that converts that extracted data to any type
T
specifies the type of the value to return
a value of type T that is the value of the DICOM element
