Property Value

This value of this property can be null (Nothing in Visual Basic).

The default value of this property is null.

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.

Your application code should check the Exception first, before accessing the operation data properties.

If you only need to test that the operation has succeeded, you can also use the OpcLabs.BaseLib.OperationModel.OperationEventArgs.Succeeded property.

This property is not serialized into XML. Instead, OpcLabs.BaseLib.OperationModel.OperationEventArgs.ErrorMessage is serialized. Deserializing from XML creates a base OpcLabs.BaseLib.OperationModel.OperationEventArgs.Exception object with just the message.

This method or property does not throw any exceptions, aside from execution exceptions such as System.Threading.ThreadAbortException or System.OutOfMemoryException.

The getter method of this property is pure, i.e. it does not have observable side effects.

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