UAAttributeData Constructor(Object,UAStatusCode)

The status code associated with the value.

Because the UAStatusCode has implicit conversions from System.Int64 and UASeverity, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a long integer (representing the internal status code value), or one of UASeverity enumeration members (representing the severity code) in place of this parameter, and the corresponding OPC UA status code will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the UAStatusCode.FromInt64 or UAStatusCode.FromUASeverity static method instead.

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

Initializes a new instance of the class, with given value and status code.
