UAReadParameters Constructor(UAQualifiedName)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA Namespace > UAReadParameters Class > UAReadParameters Constructor : UAReadParameters Constructor(UAQualifiedName)
Name of the encoding that the server should use when returning the Value attribute of a variable.

Because the OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName has an implicit conversion from System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the expanded text of the qualified name) in place of this parameter, and the corresponding OPC UA qualified name will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName.UAQualifiedName Constructor(String) constructor instead.

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

Initializes a new instance of the UAReadParameters object from an encoding name.
Syntax
'Declaration
 
Public Function New( _
   ByVal encodingName As UAQualifiedName _
)
'Usage
 
Dim encodingName As UAQualifiedName
 
Dim instance As New UAReadParameters(encodingName)
public UAReadParameters( 
   UAQualifiedName encodingName
)
public:
UAReadParameters( 
   UAQualifiedName^ encodingName

Parameters

encodingName
Name of the encoding that the server should use when returning the Value attribute of a variable.

Because the OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName has an implicit conversion from System.String, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the expanded text of the qualified name) in place of this parameter, and the corresponding OPC UA qualified name will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.AddressSpace.UAQualifiedName.UAQualifiedName Constructor(String) constructor instead.

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

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.

Remarks

The standard browse names to be used with encodingName are:

In languages that support implicit conversions (such as C# or VB.NET), in many cases you do not have call this constructor explicitly. When indicated, a call to an available equivalent implicit conversion operator will be created by the compiler automatically.

Requirements

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