Question

我写了一个Windows服务，该服务应该检查一个表，如果该表有行，那么它将创建一个报告并将其放在文件夹中。它写入用于停止和启动的时间戳记，但是OnElapsedTime不起作用。第一个代码块是服务，第二个代码块是我编写的用于发送报告的方法（我知道，在我将其作为服务之前，我对其进行了测试）。不确定为什么不会生成报告。

partial class Service2 : ServiceBase
{
    Timer timer = new Timer(); // name space(using System.Timers;) 
    public Service2()
    {
        InitializeComponent();
    }

    protected override void OnStart(string[] args)
    {
        WriteToFile("Service is started at " + DateTime.Now);
        timer.Elapsed += new ElapsedEventHandler(OnElapsedTime);
        timer.Interval = 600000; //number in milisecinds  
        timer.Enabled = true;
        timer.AutoReset = true;
        timer.Start();
    }

    protected override void OnStop()
    {
        WriteToFile("Service is stopped at " + DateTime.Now);
    }
    private void OnElapsedTime(object source, ElapsedEventArgs e)
    {
        CheckForReports();
        WriteToFile("Service is recall at " + DateTime.Now);
    }
    public void WriteToFile(string Message)
    {
        string path = AppDomain.CurrentDomain.BaseDirectory + "\\Logs";
        if (!Directory.Exists(path))
        {
            Directory.CreateDirectory(path);
        }
        string filepath = AppDomain.CurrentDomain.BaseDirectory + "\\Logs\\ServiceLog_" + DateTime.Now.Date.ToShortDateString().Replace('/', '_') + ".txt";
        if (!File.Exists(filepath))
        {
            // Create a file to write to.   
            using (StreamWriter sw = File.CreateText(filepath))
            {
                sw.WriteLine(Message);
            }
        }
        else
        {
            using (StreamWriter sw = File.AppendText(filepath))
            {
                sw.WriteLine(Message);
            }
        }
    }
    public void CheckForReports()
    {
        {
            SqlConnection sqlConnection;

            sqlConnection = new SqlConnection("Server=****;Database=ChrisCMS; Trusted_Connection=True;");
            sqlConnection.Open();

            using (sqlConnection)
            {
                SqlCommand command = new SqlCommand(
                    "Select * from SentReports;");

                SqlDataReader reader = command.ExecuteReader();

                if (reader.HasRows)
                {
                    DataClasses1DataContext classes1DataContext = new DataClasses1DataContext();
                    foreach (SentReport entity in classes1DataContext.SentReports)
                    {
                        new ReportSender.MyReportRenderer().RenderTest(entity.QueueReports);
                        classes1DataContext.SentReports.DeleteOnSubmit(entity);

                    }
                    classes1DataContext.ExecuteCommand("TRUNCATE TABLE SentReports");
                    classes1DataContext.SubmitChanges();
                }
                reader.Close();

            }


        }
    }
}

我发现了我的错误。这也是愚蠢的。方法实际上从未检查的报告我错过这是粗体下面的行：

public void CheckForReports()
{
    {
        SqlConnection sqlConnection;

        sqlConnection = new SqlConnection("Server=****;Database=ChrisCMS; Trusted_Connection=True;");
        sqlConnection.Open();

        using (sqlConnection)
        {
            SqlCommand command = new SqlCommand(
                "Select * from SentReports;");
            ***command.Connection = sqlConnection;***
            SqlDataReader reader = command.ExecuteReader();

            if (reader.HasRows)
            {
                DataClasses1DataContext classes1DataContext = new DataClasses1DataContext();
                foreach (SentReport entity in classes1DataContext.SentReports)
                {
                    new ReportSender.MyReportRenderer().RenderTest(entity.QueueReports);
                    classes1DataContext.SentReports.DeleteOnSubmit(entity);

                }
                classes1DataContext.ExecuteCommand("TRUNCATE TABLE SentReports");
                classes1DataContext.SubmitChanges();
            }
            reader.Close();

        }


    }
}

C＃Windows服务未按预期工作
