Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<NotNullAttribute()>
Property EndpointDescriptor As UAEndpointDescriptor

'Usage
 
Dim instance As _UAWriteArgumentsBase
Dim value As UAEndpointDescriptor
 
instance.EndpointDescriptor = value
 
value = instance.EndpointDescriptor

[NotNull()]
UAEndpointDescriptor EndpointDescriptor {get; set;}

[NotNull()]
property UAEndpointDescriptor^ EndpointDescriptor {
   UAEndpointDescriptor^ get();
   void set (    UAEndpointDescriptor^ value);
}

Property Value

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

Exceptions

Exception Description

Exception	Description
System.ArgumentNullException	A `null` reference (`Nothing` in Visual Basic) is passed to a method that does not accept it as a valid argument. This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

System.ArgumentNullException

A null reference (Nothing in Visual Basic) is passed to a method that does not accept it as a valid argument.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

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.

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.

Requirements

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