UAMethodOutputException Constructor(UANodeId,Int32)



OpcLabs.EasyOpcUA Assembly > OpcLabs.EasyOpc.UA Namespace > UAMethodOutputException Class > UAMethodOutputException Constructor : UAMethodOutputException Constructor(UANodeId,Int32)
The method that provided the invalid result.

Because the OpcLabs.EasyOpc.UA.AddressSpace.UANodeId 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 nodeId) in place of this parameter, and the corresponding OPC UA node Id 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.UANodeId.UANodeId Constructor(String) constructor instead.

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

The index of the argument that causes this exception.
Initializes a new instance of the class, specifying the method node Id, and argument index.

Parameters

methodNodeId
The method that provided the invalid result.

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

argumentIndex
The index of the argument that causes this exception.
Exceptions
ExceptionDescription

The value of an argument is outside the allowable range of values as defined by the invoked method.

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.
