Parameters

value: The enumeration value to be found.

Return Value

Returns an OpcLabs.BaseLib.DataTypeModel.EnumerationMember which has the value given by the parameter. When there is no such enumeration member, the function returns a null reference. When there is more than one match, the first matching enumeration member found is returned.

This method can return null (Nothing in Visual Basic).

Remarks

For finding an enumeration value that corresponds to given name, use the fact that EnumerationMembers is a collection keyed by the enumeration member names.

This member is not compatible with VBScript.

This member or type is for use from COM. It is not meant to be used from .NET or Python. Refer to the corresponding .NET member or type instead, if you are developing in .NET or Python.

Requirements

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