当用户的账号被锁定时，我如何在C#中发送短信通知消息给他/她

using QcloudSmsSharp;

public void SendSMS(string phoneNumber, string message)
{
    // 创建短信服务实例
    var smsClient = new SmsClient("yourAppId", "yourAppKey");

    // 设置短信参数
    var smsParams = new SmsParams
    {
        PhoneNumber = phoneNumber,
        Message = message,
        Sign = "yourSign",
        Extend = "",
        Ext = ""
    };

    // 发送短信
    var result = smsClient.Send(smsParams);

    // 处理发送结果
    if (result.Result == 0)
    {
        Console.WriteLine("短信发送成功！");
    }
    else
    {
        Console.WriteLine("短信发送失败：" + result.ErrMsg);
    }
}
