LowestLevel Method

Determines the lowest security level allowed by the message security modes.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
<ExtensionAttribute()>
Public Shared Function LowestLevel( _
   ByVal messageSecurityModes As UAMessageSecurityModes _
) As UAMessageSecurityModes

'Usage
 
Dim messageSecurityModes As UAMessageSecurityModes
Dim value As UAMessageSecurityModes
 
value = UAMessageSecurityModesExtension.LowestLevel(messageSecurityModes)

[Extension()]
public static UAMessageSecurityModes LowestLevel( 
   UAMessageSecurityModes messageSecurityModes
)

[Extension()]
public:
static UAMessageSecurityModes LowestLevel( 
   UAMessageSecurityModes messageSecurityModes
)

Parameters

messageSecurityModes: The message security modes.

Return Value

Returns the lowest security level allowed by the message security modes, or OpcLabs.EasyOpc.UA.Engine.UAMessageSecurityModes.None if the message security modes do not allow any security mode.

Because there is an implicit conversion from OpcLabs.EasyOpc.UA.Engine.UAMessageSecurityModes to OpcLabs.EasyOpc.UA.Engine.UAEndpointSelectionPolicy, you can simply use the returned OpcLabs.EasyOpc.UA.Engine.UAMessageSecurityModes in any place where OpcLabs.EasyOpc.UA.Engine.UAEndpointSelectionPolicy is expected as input, and the corresponding endpoint selection policy will be constructed automatically from the message security modes. When the implicit conversion operators are not supported (such as with Python.NET), you can use the FromUAMessageSecurityModes static method instead.

Remarks

This is an extension method (info: C#, VB.NET). In languages that have support for extensions methods (such as C# and VB.NET), you can use the extension method as if it were a regular method on the object that is its first parameter. In other languages (such as with Python.NET), you will call the extension as a static method, and pass it the object on which it acts as its first parameter.

Requirements

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