时间编码

DateTime dateTime = new DateTime(2024, 8, 12, 18, 0, 0);
string dateTimeString = dateTime.ToString();
byte[] dateTimeBytes = Encoding.UTF8.GetBytes(dateTimeString);
string base64String = Convert.ToBase64String(dateTimeBytes);
Console.WriteLine(base64String);


// 假设已经有经过编码的 Base64 字符串
string base64EncodedDateTime = "MjAyNC0wOC0xMiAxODowMDowMA==";
byte[] data = Convert.FromBase64String(base64EncodedDateTime);
string decodedString = Encoding.UTF8.GetString(data);
// 这里还需要将解码后的字符串转换回 DateTime 类型，具体的转换方式取决于字符串的格式
// 假设字符串格式是 "yyyy-MM-dd HH:mm:ss"
DateTime decodedDateTime = DateTime.Parse(decodedString);
Console.WriteLine(decodedDateTime);
