Question

嗨，我有以下代码，无论文件夹是否存在，我都面临的问题是它仍然继续发送电子邮件，而不是忽略发送电子邮件。

要使该功能正常运行，我需要进行哪些更改。

    static void Main(string[] args)
    {
        string yesterdaydate = DateTime.Now.AddDays(-1).ToString("yyyy-mm-dd");
        string[] SplitDate = yesterdaydate.Split('-');
        string year = SplitDate[0];
        string month = SplitDate[1];
        string day = SplitDate[2];
        string path = Path.Combine("C:\\Users\\ales\\Desktop\\test", year, month, day);

        if (Directory.Exists(path))
        {
            //do nothing
        }

        else
        {
            string fromAddress = "noreply@arm.com";
            string toAddress = "alese@arm.com";
            string subject = "error";
            string body = "failed to sync";

            krysalis_email.EmailClient email = new krysalis_email.EmailClient();
            krysalis_email.EmailClient.EmailResponse emailResponse = email.sendBasicMail(new object[] {toAddress}, fromAddress, subject, body, false, "smtp.za.arm.com",
                new string[] {"", ""}, false, null);


            if (emailResponse != null)
            {

            }

        }

    }

问题在于您将日期格式转换为字符串。您正在使用mm，这是分钟。使用MM获取月份。请记住，MM格式将为您提供前导零的月份，例如08 如果要使用字符串拆分，请将代码更改为

string yesterdaydate = DateTime.Now.AddDays(-1).ToString("yyyy-MM-dd");

但是，正如其他人指出的那样，获取值的更好方法是使用DateTime而不是解析字符串。这是一个示例：

DateTime yesterdaydate = DateTime.Now.AddDays(-1);
string year = yesterdaydate.Year.ToString();
string month = yesterdaydate.Month.ToString("D2");//D2 to format number to be zero-padded
string day = yesterdaydate.Day.ToString("D2");
string path = Path.Combine("C:\\Users\\ales\\Desktop\\test", year, month, day);

C＃If else程序无法识别if语句，仅接受else
