Remarks

Note that other extension classes for the OpcLabs.EasyOpc.AlarmsAndEvents.IEasyAEClient exist as well. Specifically, the basic set of extension methods is in the OpcLabs.EasyOpc.AlarmsAndEvents.IEasyAEClientExtension class.

This class contains extension methods (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.

This chapter describes EasyOPC.NET extensions for OPC Alarms&Events.

This functionality is not available under (or the text does not apply to) .NET 6+ development platform.
