GetDoubleValueExt(DicomElement,Int32,Int32) Method








An item in the Data Set.
The zero-based index of the first value to retrieve, when more than one value is stored in the Value Field.
Value that represents the number of values to retrieve when more than one value is stored in the Value Field. In most instances you will only retrieve one value so this parameter will be equal to one.
Returns an array of numeric values that are stored in the Value Field of the specified element. .NET support Silverlight support
Syntax
public double[] GetDoubleValueExt( 
   DicomElement element,
   int index,
   int count
)
'Declaration
 
Public Overloads Function GetDoubleValueExt( _
   ByVal element As DicomElement, _
   ByVal index As Integer, _
   ByVal count As Integer _
) As Double()
'Usage
 
Dim instance As DicomDataSet
Dim element As DicomElement
Dim index As Integer
Dim count As Integer
Dim value() As Double
 
value = instance.GetDoubleValueExt(element, index, count)
public double[] GetDoubleValueExt( 
   DicomElement element,
   int index,
   int count
)
ObjectiveC Syntax
 function Leadtools.Dicom.DicomDataSet.GetDoubleValueExt(DicomElement,Int32,Int32)( 
   element ,
   index ,
   count 
)
public:
array<double>^ GetDoubleValueExt( 
   DicomElement^ element,
   int index,
   int count
) 

Parameters

element
An item in the Data Set.
index
The zero-based index of the first value to retrieve, when more than one value is stored in the Value Field.
count
Value that represents the number of values to retrieve when more than one value is stored in the Value Field. In most instances you will only retrieve one value so this parameter will be equal to one.

Return Value

A buffer to a double value stored in the Value Field of the specified Data Element. It is null if the length of the Value Field is 0, the method was called for the incorrect Value Representation type, or the method was called for a folder (sequence) element.
Remarks

This method differs from GetDoubleValue(DicomElement,Int32,Int32) in that it can be called with any numeric value representation. This includes the following:

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

If you have more than one value stored in the Value Field of the specified Data Element, you can retrieve one or more of those elements. For example, if the Value Field of the specified Data Element contains three numeric values, and you are only interested in retrieving the last two numeric values, set index to 1 and count to 2. This tells the method to retrieve the numeric values starting at position 1 (the index is zero-based) and retrieve two values. Therefore you would retrieve the values in positions 1 and 2 in the Value Field.
Example
For an example, refer to SetDoubleValueExt.
