Array of endpoint descriptor objects.
Syntax
'Declaration
 
<NotNullAttribute()>
Public Property EndpointDescriptors As UAEndpointDescriptor()
'Usage
 
Dim instance As UADataDialog
Dim value() As UAEndpointDescriptor
 
instance.EndpointDescriptors = value
 
value = instance.EndpointDescriptors
[NotNull()]
public UAEndpointDescriptor[] EndpointDescriptors {get; set;}

public:
property array<UAEndpointDescriptor^>^ EndpointDescriptors {
   array<UAEndpointDescriptor^>^ get();
   void set (    array<UAEndpointDescriptor^>^ value);
}

Property Value

The value of this property cannot be null (Nothing in Visual Basic).

The individual elements of the property value cannot be null (Nothing in Visual Basic).

Remarks

When multi-select is enabled and the dialog allows the user to pick the OPC-UA endpoint, the count of endpoint descriptors must be the same as the count of node descriptors.

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

Because the OpcLabs.EasyOpc.UA.UAEndpointDescriptor has an implicit conversion from System.String and System.Uri, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a string (representing the endpoint URL, or a so-called OPC UA endpoint descriptor string), or a System.Uri object, when setting this property, and the corresponding endpoint descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.UAEndpointDescriptor.FromString or OpcLabs.EasyOpc.UA.UAEndpointDescriptor.FromUri static method instead.

Also, because the OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement and OpcLabs.EasyOpc.UA.Discovery.UADiscoveryElement have an implicit conversion to OpcLabs.EasyOpc.UA.UAEndpointDescriptor, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement or OpcLabs.EasyOpc.UA.Discovery.UADiscoveryElement (results from OPC UA discovery) in place of OpcLabs.EasyOpc.UA.UAEndpointDescriptor when setting this property, and the corresponding endpoint descriptor will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can convert a (non-null) OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement or OpcLabs.EasyOpc.UA.Discovery.UADiscoveryElement to OpcLabs.EasyOpc.UA.UAEndpointDescriptor using the OpcLabs.EasyOpc.UA.Discovery.UAApplicationElement.ToUAEndpointDescriptor or OpcLabs.EasyOpc.UA.Discovery.UADiscoveryElement.ToUAEndpointDescriptor method instead.
