SA1401 字段必须声明为私有访问。使用属性公开字段

Question

我面临以下 StyleCop 违规行为。我该如何解决这个问题？

警告 SA1401：CSharp.Maintainability：字段必须声明为具有私有访问权限。使用属性来公开字段。监控GitLabProjectStatus

我的代码是

    public class EmailConfig
    {

        public EmailConfig()
        {
            this.AmazonClient = new AmazonSimpleEmailServiceClient(this.amazonUserName, this.amazonPassword);
        }
        protected MailMessage mailMessage = new MailMessage(); //Fields must be declared with private access. Use properties to expose fields
        protected RawMessage rawMessage = new RawMessage();  //Fields must be declared with private access. Use properties to expose fields
        protected SendRawEmailRequest request = new SendRawEmailRequest(); //Fields must be declared with private access. Use properties to expose fields
        protected List<string> mailNotifications = new List<string>(); //Fields must be declared with private access. Use properties to expose fields
        protected List<string> additionalNotifications = new List<string>(); //Fields must be declared with private access. Use properties to expose fields
        protected List<string> additionalNotificationsinBCC = new List<string>(); //Fields must be declared with private access. Use properties to expose fields
        private string amazonUserName = "user name";
        private string amazonPassword = "Password";
        public AmazonSimpleEmailServiceClient AmazonClient { get; protected set; }
    }
    public class EmailSenderThread : EmailConfig
    {
        private Thread msgThread;
        public EmailSenderThread(List<string> emailAddresses, List<string> ccemailaddress, List<string> bccemailaddress, string from, string subject, string body, string attachmentFileName)
            : base()
        {
            try
            {
                this.msgThread = new Thread(new ThreadStart(this.MailSender));
                mailMessage.From = new MailAddress(string.IsNullOrEmpty(from) ? "gitlabteam@syncfusion.com" : from);
                if (emailAddresses != null)
                {
                    var tomails = emailAddresses;
                    foreach (string tomail in tomails)
                    {
                        if (!string.IsNullOrEmpty(tomail))
                        {
                            mailMessage.To.Add(new MailAddress(tomail));
                            mailNotifications.Add(tomail);
                        }
                    }                            
                }

                if (ccemailaddress != null)
                {
                    var ccemails = ccemailaddress;
                    foreach (string ccmail in ccemails)
                    {
                        if (!string.IsNullOrEmpty(ccmail))
                        {
                            mailMessage.CC.Add(new MailAddress(ccmail));
                            additionalNotifications.Add(ccmail);
                        }
                    }                            
                }

                if (bccemailaddress != null)
                {
                    var bccemails = bccemailaddress;
                    foreach (string bccmail in bccemails)
                    {
                        if (!string.IsNullOrEmpty(bccmail))
                        {
                            mailMessage.Bcc.Add(new MailAddress(bccmail));
                            additionalNotificationsinBCC.Add(bccmail);
                        }
                    }                           
                }

                mailMessage.Subject = subject;
                AlternateView htmlView = AlternateView.CreateAlternateViewFromString(body, Encoding.UTF8, "text/html");
                if (body != null)
                {
                    mailMessage.AlternateViews.Add(htmlView);
                }

                if (!string.IsNullOrEmpty(attachmentFileName))
                {
                    var attachment = new Attachment(attachmentFileName);
                    mailMessage.Attachments.Add(attachment);
                }

                MemoryStream memoryStream = ConvertMailMessage.ConvertMailMessageToMemoryStream(mailMessage);
                rawMessage.WithData(memoryStream);
                request.WithRawMessage(this.rawMessage);
                request.WithDestinations(this.mailNotifications);
                request.WithDestinations(this.additionalNotifications);
                request.WithDestinations(this.additionalNotificationsinBCC);
                request.WithSource(from);
                this.msgThread.Start();
            }
            catch (Exception ex)
            {
                Console.WriteLine("Exception in mail sending: {0}", ex);
            }
        }

我标记了我面临 StyleCop 违规的注释行。我不知道如何访问 public 类 EmailSenderThread : EmailConfig 中的 Private 字段。如果我更改 Private 而不是 protected 意味着我在 public class EmailSenderThread : EmailConfig 中遇到异常。我尝试通过为 EmailConfig 创建对象来修复错误。但没用过。

您应该使用 C# 属性。

例如：

public class EmailConfig
{
    public EmailConfig()
    {
        this.AmazonClient = new AmazonSimpleEmailServiceClient(this.amazonUserName, this.amazonPassword);
    }
    protected MailMessage MailMessage { get; set; } = new MailMessage(); //Fields must be declared with private access. Use properties to expose fields
    protected RawMessage RawMessage { get; set; } = new RawMessage();  //Fields must be declared with private access. Use properties to expose fields
    protected SendRawEmailRequest Request { get; set; } = new SendRawEmailRequest(); //Fields must be declared with private access. Use properties to expose fields
    protected List<string> MailNotifications { get; set; } = new List<string>(); //Fields must be declared with private access. Use properties to expose fields
    protected List<string> AdditionalNotifications { get; set; } = new List<string>(); //Fields must be declared with private access. Use properties to expose fields
    protected List<string> AdditionalNotificationsinBCC { get; set; } = new List<string>(); //Fields must be declared with private access. Use properties to expose fields
    private string amazonUserName = "user name";
    private string amazonPassword = "Password";
    public AmazonSimpleEmailServiceClient AmazonClient { get; protected set; }
}
