Implicit Type Conversion(Int32,DAQuality) Operator



OpcLabs.EasyOpcClassicCore Assembly > OpcLabs.EasyOpc.DataAccess Namespace > DAQuality Class > Implicit Type Conversion Operator : Implicit Type Conversion(Int32,DAQuality) Operator
A quality 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 the quality to an integer.

Parameters

quality
A quality 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 a bit-coded integer that corresponds to the quality.
Remarks

This operator is equivalent to ToInt32.

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
