我有一个 Windows 服务，它应该检查记录，通过电子邮件发送该记录的报告，删除记录，然后对表格重复。它检查记录，通过电子邮件发送第一条记录的报告，然后关闭。有任何想法吗？？
服务代码：
namespace ReportSender
{
public partial class EmailReportService : ServiceBase
{
private EmailReportApp _app = new EmailReportApp();
public Timer serviceTimer = new Timer();
public EmailReportService()
{
InitializeComponent();
}
protected override void OnStart(string[] args)
{
//Set interval (from App Settings) and enable timer
serviceTimer.Elapsed += new ElapsedEventHandler(ServiceTimer_OnElapsed);
//Use Conversion utility to determine next start date/time based on properties, use DateTime.Subtract() to find milliseconds difference between Now and the next start time
//serviceTimer.Interval = Date.AddInterval(Properties.Settings.Default.IntervalType, Properties.Settings.Default.Interval).Subtract(DateTime.Now).TotalMilliseconds;
serviceTimer.Interval = 600000;
serviceTimer.Enabled = true;
}
protected override void OnStop()
{
//Stop and disable timer
serviceTimer.Enabled = false;
}
private void ServiceTimer_OnElapsed(object source, ElapsedEventArgs e)
{
try
{
//Stop the timer to prevent overlapping runs
serviceTimer.Stop();
//Start service
//Run your app.Start() code
_app = new EmailReportApp();
_app.Start();
}
catch (Exception ex)
{
}
finally
{
//Re-start the timer
serviceTimer.Start();
}
}
}
}
服务应该执行的代码：
namespace ReportSender
{
class EmailReportApp
{
// Private fields
private Thread _thread;
private EventLog _log;
private void Execute()
{
try
{
// Check for a new record
DataClasses1DataContext dc = new DataClasses1DataContext();
foreach (var item in dc.reportsSent1s)
{
string matchedCaseNumber = item.CaseNumberKey;
(new MyReportRenderer()).RenderTest(matchedCaseNumber);
dc.reportsSent1s.DeleteOnSubmit(item);
dc.SubmitChanges();
}
}
catch (ThreadAbortException ex)
{
_log.WriteEntry(ex.StackTrace.ToString());
}
}
public void Start()
{
if (!EventLog.SourceExists("EventLoggerSource"))
EventLog.CreateEventSource("EventLoggerSource", "Event Logger");
_log = new EventLog("EventLoggerSource");
_log.Source = "EventLoggerSource";
_thread = new Thread(new ThreadStart(Execute));
_thread.Start();
}
public void Stop()
{
if (_thread != null)
{
_thread.Abort();
_thread.Join();
}
}
}
public class MyReportRenderer
{
private rs2005.ReportingService2005 rs;

rsExec = new rs2005Execution.ReportExecutionService();
rs.Credentials = System.Net.CredentialCache.DefaultCredentials;
rsExec.Credentials = System.Net.CredentialCache.DefaultCredentials;
rs.Url = "http://***.**.***.**/ReportServer_DEVELOPMENT/ReportService2005.asmx";
rsExec.Url = "http://***.**.***.**/ReportServer_DEVELOPMENT/ReportExecution2005.asmx";
try
{
// Load the selected report.
rsExec.LoadReport("/LawDept/LawDeptTIC", HistoryID);
// Set the parameters for the report needed.
rs2005Execution.ParameterValue[] parameters = new rs2005Execution.ParameterValue[1];
parameters[0] = new rs2005Execution.ParameterValue();
parameters[0].Name = "CaseNumberKey";
parameters[0].Value = matchedCaseNumber;
rsExec.SetExecutionParameters(parameters, "en-us");
// get pdf of report
Byte[] results = rsExec.Render("PDF", deviceInfo,
out extension, out encoding,
out mimeType, out warnings, out streamIDs);
//pass paramaters for email
DataClasses1DataContext db = new DataClasses1DataContext();
var matchedBRT = (from c in db.GetTable<vw_ProductClientInfo>()
where c.CaseNumberKey == matchedCaseNumber
select c.BRTNumber).SingleOrDefault();
var matchedAdd = (from c in db.GetTable<vw_ProductClientInfo>()
where c.CaseNumberKey == matchedCaseNumber
select c.Premises).SingleOrDefault();
//send email with attachment
MailMessage message = new MailMessage("234@acmetaxabstracts.com", "georr@gmail.com", "Report for BRT # " + matchedAdd, "Attached if the Tax Information Certificate for the aboved captioned BRT Number");
MailAddress copy = new MailAddress("a123s@gmail.com");
message.CC.Add(copy);
SmtpClient emailClient = new SmtpClient("***.**.***.**");
message.Attachments.Add(new Attachment(new MemoryStream(results), String.Format("{0}" + matchedBRT + ".pdf", "BRT")));
emailClient.Send(message);
}
catch (Exception ex)
{
}
}
}
