Syntax
'Declaration
 
Public Property AllowZeroSecurityLevel As Boolean
'Usage
 
Dim instance As UAEndpointSelectionPolicy
Dim value As Boolean
 
instance.AllowZeroSecurityLevel = value
 
value = instance.AllowZeroSecurityLevel
public bool AllowZeroSecurityLevel {get; set;}
public:
property bool AllowZeroSecurityLevel {
   bool get();
   void set (    bool value);
}

Property Value

The default value of this property is True.

Remarks

A security level value of 0 indicates that the EndpointDescription is not recommended and is only supported for backward compatibility.

In order to obtain or modify this parameter, in the default state (when $(memberUrl equals to false), access EndpointSelectionPolicy property of UAClientAdaptableParameters.SessionParameters property of static $(memberUrl. If you have set $(memberUrl to true, you need to access EndpointSelectionPolicy property of UAClientAdaptableParameters.SessionParameters property of $(memberUrl.

Alternatively, you can override the endpoint selection policy for a specific endpoint by setting it to a non-null value in OpcLabs.EasyOpc.UA.UAEndpointDescriptor.EndpointSelectionPolicy.

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
