Implicit Type Conversion(DAPropertyIds,DAPropertyId) Operator



OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.DataAccess Namespace > DAPropertyId Class > Implicit Type Conversion Operator : Implicit Type Conversion(DAPropertyIds,DAPropertyId) Operator
DAPropertyId object to be converted.

Because the DAPropertyId has an implicit conversion from System.Int64 and DAPropertyIds, 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 access rights), or an element of the DAPropertyIds enumeration in place of this parameter, and the corresponding Property Id specification will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the DAPropertyId Constructor(Int64) or DAPropertyId Constructor(DAPropertyIds) constructor instead.

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

Converts DAPropertyId object to an enumerated value.

Parameters

propertyId
DAPropertyId object to be converted.

Because the DAPropertyId has an implicit conversion from System.Int64 and DAPropertyIds, 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 access rights), or an element of the DAPropertyIds enumeration in place of this parameter, and the corresponding Property Id specification will be constructed automatically.

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

Return Value

Returns an enumerate values converted from the input argument.
Remarks

This operator is equivalent to ToDAPropertyIds.

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
