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

Because the OpcLabs.EasyOpc.UA.UAStatusCode has implicit conversions from System.Int64 and OpcLabs.EasyOpc.UA.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 OpcLabs.EasyOpc.UA.UASeverity enumeration members (representing the severity code) in place of OpcLabs.EasyOpc.UA.UAStatusCode value when setting this property, 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 OpcLabs.EasyOpc.UA.UAStatusCode.FromInt64 or OpcLabs.EasyOpc.UA.UAStatusCode.FromUASeverity static method instead.
