Property Value

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

Remarks

Determines how the UA client chooses the endpoint from the endpoints provided by the UA server. It is used in conjunction with non-empty EndpointUriString.

Because the OpcLabs.EasyOpc.UA.Engine.UAEndpointSelectionPolicy has an implicit conversion from OpcLabs.EasyOpc.UA.Engine.UAMessageSecurityModes, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.Engine.UAMessageSecurityModes in place of OpcLabs.EasyOpc.UA.Engine.UAEndpointSelectionPolicy value when setting this property, and the corresponding OPC UA endpoint selection policy will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.Engine.UAEndpointSelectionPolicy.UAEndpointSelectionPolicy Constructor(UAMessageSecurityModes) constructor instead.

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.

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

Requirements

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