Parameters

internalValue
Enumerated type to be converted.

Valid values of this parameter are in the range from Empty (VarTypes.Empty) to Illegal (VarTypes.Illegal).

Exceptions
ExceptionDescription

The value of an argument is outside the allowable range of values as defined by the invoked method.

This is a usage error, i.e. it will never occur (the exception will not be thrown) in a correctly written program. Your code should not catch this exception.

Remarks

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

Requirements

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