// To find out source and target

foreach (var sourceEncoding in Encoding.GetEncodings())

            Console.WriteLine("Source Encoding: {0} TargetEncoding: {1}",sourceEncoding.CodePage,targetEncoding.CodePage);
        }

    }
}

// Result1: Source Encoding: 1252 TargetEncoding: 1251
// Result2: Source Encoding: 28591 TargetEncoding: 1251
// Result3: Source Encoding: 28605 TargetEncoding: 1251

// The code for you to use 
var decodedCyrillic = Encoding.GetEncoding(1251).GetString(Encoding.GetEncoding(1252).GetBytes(source));
// Result: Работа в германии
