I am trying to deserialize using below code

var timeZoneObj=  TimeZoneInfo.FromSerializedString(timeZoneInfo.Value);

I am getting the exception as An error occurred while deserializing the object. The serialized data is corrupt.

Answer 1

The exception is justified, because the input string is indeed corrupt, missing its delimiting semicolons. Use a valid string generated from TimeZoneInfo.ToSerializedString() as input to TimeZoneInfo.FromSerializedString() .

While MSDN ( https://msdn.microsoft.com/en-us/library/system.timezoneinfo.toserializedstring(v=vs.110).aspx ) does not point out any such potential problems, it might be that your input string has been generated on a different platform/encoding/framework version.

Answer 2

Same problem. I get the timezones from IEnumerable allTimeZones = TimeZoneInfo.GetSystemTimeZones();

taking eg the DisplayName of an element: (UTC+02:00) Harare, Pretoria

I run: TimeZoneInfo.FromSerializedString( "(UTC+02:00) Harare, Pretoria" )

in the immediate window which gives an error.

I also tried the StandardName: South Africa Standard Time but TimeZoneInfo.FromSerializedString( "South Africa Standard Time" )

also generates the exception.
