ToInt64 Method (AEEventType)



OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.AlarmsAndEvents Namespace > AEEventType Class : ToInt64 Method
An AEEventType object value to be converted.

Because the AEEventType has an implicit conversion from System.Int64 and AEEventTypes, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a long integer (representing the numerical value of the event types), or an element of the AEEventTypes enumeration (or a combination of AEEventTypes flags) in place of this parameter, and the corresponding event type specification will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the AEEventType Constructor(Int64) or AEEventType Constructor(AEEventTypes) constructor instead.

The value of this parameter can be null (Nothing in Visual Basic).

Converts an AEEventType object to a numerical bit-coded value.
Syntax
'Declaration
 
Public Shared Function ToInt64( _
   ByVal eventType As AEEventType _
) As Long
'Usage
 
Dim eventType As AEEventType
Dim value As Long
 
value = AEEventType.ToInt64(eventType)
public static long ToInt64( 
   AEEventType eventType
)
public:
static int64 ToInt64( 
   AEEventType^ eventType

Parameters

eventType
An AEEventType object value to be converted.

Because the AEEventType has an implicit conversion from System.Int64 and AEEventTypes, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use a long integer (representing the numerical value of the event types), or an element of the AEEventTypes enumeration (or a combination of AEEventTypes flags) in place of this parameter, and the corresponding event type specification will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the AEEventType Constructor(Int64) or AEEventType Constructor(AEEventTypes) constructor instead.

The value of this parameter can be null (Nothing in Visual Basic).

Return Value

Returns a bit-coded value converted from the input argument.
Remarks

In languages that support implicit conversions (such as C# or VB.NET), in many cases you do not have call this method explicitly. When indicated, a call to an available equivalent implicit conversion operator will be created by the compiler automatically.

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

Requirements

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