FromUAQualifiedName Method (UAReadParameters)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA Namespace > UAReadParameters Class : FromUAQualifiedName Method
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).

Converts an encoding name to a UAReadParameters object.

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).

Return Value

Returns a UAReadParameters object converted from the input argument.

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

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 method 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
