Syntax
'Declaration
 
Property AlwaysPreselectEndpoint As Boolean
'Usage
 
Dim instance As _UAClientSessionParameters
Dim value As Boolean
 
instance.AlwaysPreselectEndpoint = value

bool AlwaysPreselectEndpoint {get; set;}
property bool AlwaysPreselectEndpoint {
   bool get();
   void set (    bool value);
}
Remarks

The endpoint is selected using the EndpointSelectionPolicy.

This property should always be 'true' in the current version.

In order to obtain or modify this parameter, in the default state (when OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated equals to false), access OpcLabs.EasyOpc.UA.Engine.UAClientAdaptableParameters.SessionParameters property of static OpcLabs.EasyOpc.UA.EasyUAClientCore.AdaptableParameters. If you have set OpcLabs.EasyOpc.UA.EasyUAClientCore.Isolated to true, you need to access OpcLabs.EasyOpc.UA.Engine.UAClientAdaptableParameters.SessionParameters property of OpcLabs.EasyOpc.UA.EasyUAClientCore.IsolatedParameters.

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