TryConvertWindowsIdToIanaId(String, String)

Source:

TimeZoneInfo.cs

Tries to convert a Windows time zone ID to an IANA ID.

public:
 static bool TryConvertWindowsIdToIanaId(System::String ^ windowsId, [Runtime::InteropServices::Out] System::String ^ % ianaId);

public static bool TryConvertWindowsIdToIanaId (string windowsId, out string? ianaId);

static member TryConvertWindowsIdToIanaId : string * string -> bool

Public Shared Function TryConvertWindowsIdToIanaId (windowsId As String, ByRef ianaId As String) As Boolean

Parameters

windowsId

String

The Windows time zone ID.

ianaId

String

When this method returns, contains the IANA ID that corresponds to the specified Windows ID.

Returns

Boolean

true if the ID conversion succeeded, false otherwise.

Remarks

This API is exclusively supported on .NET 6.0 and later versions. It is also supported when the application utilizes the ICU library, otherwise the API will fail. However, in .NET, the ICU library is not always used by default, particularly in the following scenarios:

• When the application runs on an operating system that does not have the ICU library, and the app does not utilize the APP-Local ICU feature.
• When the Globalization Invariant Mode or NLS mode is enabled on Windows OS.

If the application is running on a Windows OS version that lacks the ICU library, it has the option to opt-in and enable the usage of the ICU library through the App-Local ICU feature.
