ToDAQualities Method



OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.DataAccess Namespace > DAQuality Class : ToDAQualities Method
DAQuality object to be converted.

Because the DAQuality has an implicit conversion from System.Int32 and DAQualities, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the internal value of the quality), or an element of the DAQualities enumeration in place of this parameter, and the corresponding OPC DA quality object will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the DAQuality Constructor(Int32) or DAQuality Constructor(DAQualities) constructor instead.

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

Converts DAQuality object to an enumerated value.
Syntax
'Declaration
 
Public Shared Function ToDAQualities( _
   ByVal quality As DAQuality _
) As DAQualities
'Usage
 
Dim quality As DAQuality
Dim value As DAQualities
 
value = DAQuality.ToDAQualities(quality)
public static DAQualities ToDAQualities( 
   DAQuality quality
)
public:
static DAQualities ToDAQualities( 
   DAQuality^ quality
) 

Parameters

quality
DAQuality object to be converted.

Because the DAQuality has an implicit conversion from System.Int32 and DAQualities, in languages that support implicit conversion operators (such as C# or VB.NET), you can simply use an integer (representing the internal value of the quality), or an element of the DAQualities enumeration in place of this parameter, and the corresponding OPC DA quality object will be constructed automatically. When the implicit conversion operators are not supported (such as with Python.NET), you can use the DAQuality Constructor(Int32) or DAQuality Constructor(DAQualities) constructor instead.

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

Return Value

Returns an enumerated 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
