Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Property SubscriptionParameters As UASubscriptionParameters

'Usage
 
Dim instance As UAMonitoredItemArguments
Dim value As UASubscriptionParameters
 
instance.SubscriptionParameters = value
 
value = instance.SubscriptionParameters

public UASubscriptionParameters SubscriptionParameters {get; set;}

public:
property UASubscriptionParameters^ SubscriptionParameters {
   UASubscriptionParameters^ get();
   void set (    UASubscriptionParameters^ value);
}

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.UASubscriptionParameters has an implicit conversion from System.Int32, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the publishing interval in milliseconds) in place of OpcLabs.EasyOpc.UA.UASubscriptionParameters value when setting this property, and the corresponding OPC UA subscription parameters will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the OpcLabs.EasyOpc.UA.UASubscriptionParameters.FromInt32 static method instead.

Requirements

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