SetArrayDimensions Method (UADataVariableExtension)

Sets the array dimensions of this data variable.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<ExtensionAttribute()>
<JetBrains.Annotations.NotNullAttribute()>
Public Shared Function SetArrayDimensions( _
   ByVal dataVariable As UADataVariable, _
   ByVal arrayDimensionList As IReadOnlyList(Of Integer) _
) As UADataVariable

'Usage
 
Dim dataVariable As UADataVariable
Dim arrayDimensionList As IReadOnlyList(Of Integer)
Dim value As UADataVariable
 
value = UADataVariableExtension.SetArrayDimensions(dataVariable, arrayDimensionList)

[Extension()]
[JetBrains.Annotations.NotNull()]
public static UADataVariable SetArrayDimensions( 
   UADataVariable dataVariable,
   IReadOnlyList<int> arrayDimensionList
)

[Extension()]
[JetBrains.Annotations.NotNull()]
public:
static UADataVariable^ SetArrayDimensions( 
   UADataVariable^ dataVariable,
   IReadOnlyList<int>^ arrayDimensionList
)

Parameters

dataVariable: The data variable that will be modified and returned.
The value of this parameter cannot be null (Nothing in Visual Basic).
arrayDimensionList: The size of each dimension of the array value.
The value of this parameter cannot be null (Nothing in Visual Basic).

Return Value

Returns the , internally modified as defined by the method.

This method never returns null (Nothing in Visual Basic).

Exceptions

Exception Description

Exception	Description
System.ArgumentNullException	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.

System.ArgumentNullException

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.

Remarks

The array dimensions are specified as a list of integers, one for each dimension. Each element represents a dimension of the array, and the value of the element represents the maximum size of the array in that dimension. If the maximum size of certain dimension is unknown, the value of corresponding element is 0.

The specified array dimensions will be stored in the ArrayDimensions property, and exposed to OPC UA clients via the OpcLabs.EasyOpc.UA.UAAttributeId.ArrayDimensions attribute. In addition, OPC Wizard will enforce the maximum array bounds automatically (where the specified array dimension is not 0).

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.

Requirements

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