UAIndexRange Constructor(UAIndexRange)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA Namespace > UAIndexRange Class > UAIndexRange Constructor : UAIndexRange Constructor(UAIndexRange)
The index range to copy from.

Because the UAIndexRange has an implicit conversion from System.Int32, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (containing the single index that is both the minimum and maximum of the range) in place of this parameter, and the corresponding OPC UA index range will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UAIndexRange Constructor(Int32) constructor instead.

The value of this parameter cannot be null (Nothing in Visual Basic).

Create a range by copying data from another range.
Syntax
'Declaration
 
Public Function New( _
   ByVal indexRange As UAIndexRange _
)
'Usage
 
Dim indexRange As UAIndexRange
 
Dim instance As New UAIndexRange(indexRange)
public UAIndexRange( 
   UAIndexRange indexRange
)
public:
UAIndexRange( 
   UAIndexRange^ indexRange
)

Parameters

indexRange
The index range to copy from.

Exceptions
ExceptionDescription

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Requirements

Target Platforms: .NET Framework: Windows 10 (selected versions), Windows 11 (selected versions), Windows Server 2016, Windows Server 2022; .NET: Linux, macOS, Microsoft Windows
