我需要比较两个日期时间值以确定相等(完全相同),使用精确度.这是最好的方法吗？我的日期可能有几秒和几毫秒,但我想只考虑到几分钟.

       where (Math.Abs(datetime1.Subtract(datetime2).TotalMinutes) == 0)

我正在使用c#.NET 4.0编写Windows服务(我的开发工作站是Windows 7).目的是在处理过程中出现错误时直接从服务发送电子邮件.我已经包含了一个代码片段来展示我想要实现的目标:

try
        {
                string emailAddresses = "me@sample.com";
                string emailCCAddresses = "you@sample.com";

                //Send the email
                using (MailMessage mailMsg = new MailMessage())
                {
                    mailMsg.To.Add(emailAddresses);
                    mailMsg.From = new MailAddress("winService@sample.com");
                    mailMsg.CC.Add(emailCCAddresses);
                    mailMsg.Subject = " Error Message ";
                    mailMsg.Body = DateTime.Now + " : Invalid File Encountered." ;

                    ////Creating the file attachment
                    using (Attachment data = new Attachment("C:\\users\\sample.xml", MediaTypeNames.Application.Octet))
                    {
                        //Add timestamp info for the file
                        ContentDisposition disposition = data.ContentDisposition;
                        disposition.ModificationDate = File.GetLastWriteTime("C:\\users\\sample.xml");
                        mailMsg.Attachments.Add(data);

                    SmtpClient emailClient = new SmtpClient("example.Sample.com", 25);
                    emailClient.DeliveryMethod = SmtpDeliveryMethod.Network; …
