服务器上的C#/Webservice应用程序引发奇怪异常

我们使用ADP获取员工信息。我必须创建一个称为web服务的小应用程序,ADP必须提取员工信息。这个应用程序相当程序化。从某种意义上说,它不是真正面向对象的。基本上,我通过一些web服务来获取一般信息、工作信息、员工状态等。

我将这些数据的大部分作为日志写入文本文件,这样我就可以确保一切正常工作。终于全部完成了,它在我的本地机器上运行得非常完美。我想我应该将整个结构复制到服务器上,然后使用windows调度程序来安排exe每晚(每天一次)运行。当它尝试运行该应用程序时,调用第一个web服务时,它看起来好像快死了。任务计划程序日志显示:

""ADP.job" (ADP.exe)
    Started 2/11/2010 2:14:34 PM
"ADP.job" (ADP.exe)
    Finished 2/11/2010 2:14:38 PM
    Result: The task completed with an exit code of (e0434f4d)."

所以我检查了事件查看器,它说:

事件类型clr20r3、P1 adp.exe、P2 1.0.0.0、P3 4b745bb9、P4 adp、P5 1.0.0.0、P6 4b745bb9、P7 289、P8 2d、P9 system.io.filenotfoundexception、P10 NIL。

我放了一些控制台,看看哪里出了问题。。。

以下是一个简单的主要示例:

 static void Main(string[] args)
        {
            OpenTextFile();

            Console.WriteLine("About to process employee work information...");
            tw.WriteLine("About to process employee work information...");
            //work info service
            EmpWorkInfo();
         }

以及opentextfile的内部:

  public static void OpenTextFile()
        {
            //used to log data
            String sLogName;
            Console.WriteLine("Inside of opentextfile");
            if (Directory.Exists(logPath))
            {
                //directory exists
            }
            else
            {
                Directory.CreateDirectory(logPath);
            }
            Console.WriteLine("Inside of opentextfile2");
            sLogName = "log_" + DateTime.Today.ToString("MM_dd_yyyy") + ".txt";
            tw = new StreamWriter(logPath + sLogName);
        }

我看到服务器上的所有console.writelines,但一旦它从main中点击这一行:

EmpWorkInfo();

static void EmpWorkInfo()
{
    Console.Writeline("THIS NEVER PRINTS!!!");
    SQLClass s=null;
    // Create the web service proxy client.
    GetEmployeeWorkInfoService oService = new GetEmployeeWorkInfoService();
    oService.Timeout = Int32.MaxValue;
    // Serialize the UsernameToken into XML.
    // Create the UsernameToken as defined in the WS-I secure profile.
    UsernameToken oUsernameToken = new UsernameToken(USERNAME, SECRET);

    System.Xml.XmlElement oSecurityHeaderXml =
    oUsernameToken.GetXml(new System.Xml.XmlDocument());

    ADP.GetEmployeeWorkInfoWebService.SecurityHeaderType oSecurityHeader = new ADP.GetEmployeeWorkInfoWebService.SecurityHeaderType();
    oSecurityHeader.Any = new System.Xml.XmlElement[] { oSecurityHeaderXml };
    oService.Security = oSecurityHeader;

    GetEmployeeWorkInfoRequestFilter oFilter = new GetEmployeeWorkInfoRequestFilter();

    //filter by thyssenkrupp company
    oFilter.Companies = new String[] { COMPANY_IDENTIFIER };

    GetEmployeeWorkInfoRequest oRequest = new GetEmployeeWorkInfoRequest();
    oRequest.Filter = oFilter;

    try
    {
        EmployeeWorkInfoType[] arPersonalInfo = oService.GetEmployeeWorkInfo(oRequest);
        try
        {
            s = new SQLClass();
        }
        catch (Exception e)
        {
            throw new System.Exception(e.Message.ToString());
        }

        for (int i = 0; i < arPersonalInfo.Length; i++)
        {

            String stID = arPersonalInfo[i].EmployeeKey.Identifier.EmployeeId;  //employee number
            String stEmailAddress = arPersonalInfo[i].WorkInfo.EmailAddress;    //employee email address (work)
            String stFax = arPersonalInfo[i].WorkInfo.Fax;                      //employee fax number
            DateTime dtHireDate = arPersonalInfo[i].WorkInfo.OriginalHireDate;

            String stPhone = arPersonalInfo[i].WorkInfo.Phone;                  //employee phone number
            String stWireless = arPersonalInfo[i].WorkInfo.Wireless;            //employee wireless number
            tw.WriteLine("Processing ID:" + stID + " Email Work: " + stEmailAddress + " Fax Work: " + stFax + " Hire Date: " + dtHireDate + " Phone Work: " + stPhone + " Wireless Work: " + stWireless + ".");
            Console.WriteLine("Processing ID:" + stID + " Email Work: " + stEmailAddress + " Fax Work: " + stFax + " Hire Date: " + dtHireDate + " Phone Work: " + stPhone + " Wireless Work: " + stWireless + ".");
            s.SetSQLCommand("dbo.ADP_uiEmployeeWorkInfo");
            s.AddSQLCmdParameter("@EmployeeNumber", System.Data.SqlDbType.VarChar, stID);
            s.AddSQLCmdParameter("@EmailAddress", System.Data.SqlDbType.VarChar, stEmailAddress);
            s.AddSQLCmdParameter("@Fax", System.Data.SqlDbType.VarChar, stFax);
            s.AddSQLCmdParameter("@HireDate", System.Data.SqlDbType.DateTime, dtHireDate);
            s.AddSQLCmdParameter("@Telephone", System.Data.SqlDbType.VarChar, stPhone);
            s.AddSQLCmdParameter("@Mobile", System.Data.SqlDbType.VarChar, stWireless);
            s.SQLExecuteNonQuery();                   

            Console.WriteLine("Processed ID:" + stID + " Email Work: " + stEmailAddress + " Fax Work: " + stFax + " Hire Date: " + dtHireDate + " Phone Work: " + stPhone + " Wireless Work: " + stWireless + ".");
            Console.WriteLine(Environment.NewLine);
        }
        s.CloseSQLDB();
        s.Dispose();
    }
    //catch any exception from adp side.
    catch (Exception e)
    {
        throw new System.Exception(e.Message.ToString());
    }
}

这个函数代码是不相关的(它很难看,但不要让它打扰你,代码可以工作…)。我的问题是我甚至无法访问该函数的第一个控制台.writeline。在使用Web服务时,我需要做什么特别的事情吗?

编辑

Logpath仅定义为main之外的静态字符串:

private static string logPath = Environment.CurrentDirectory + "\\log\\";
