静态类和Business Objects COM库

以下代码来自winforms应用程序,该应用程序在按钮事件上打开业务对象6.5的实例,刷新报表,然后将报表中的数据转储到csv文件中,然后退出业务对象实例。

我第一次运行代码时效果很好,但是如果我再次运行它会在行上出现异常

boApp.LoginAs(userName, Password, false, null);

引发的异常是“无效对象”。

我认为这是因为boApp没有被重新初始化,而且我缺乏关于静态类的知识。

调用方法是:

BO_Control.RefreshBusinessObjects(boReportsFolder, boExportsFolder, boReportName, exportFileName, startDate, endDate);

这是BO_Control类

static class BO_Control
{

    static busobj.Application boApp = new busobj.Application();
    static busobj.Document testDoc;


   public static void RefreshBusinessObjects(string reportFolder, string exportFolder ,string boReportName, string exportFileName, string startDate, string endDate)      
   {


        DateTime BoStart = DateTime.Now;

        boApp.LoginAs(userName, Password, false, null);

        boApp.Interactive = false;
        boApp.Visible = false;

        GetData(reportFolder, boReportName, startDate, endDate);
        ExportData(exportFolder, exportFileName);

        Console.WriteLine("BO_Export took {0} seconds.", DateTime.Now.Subtract(BoStart));

        boApp.Quit();          
   }

   static busobj.Document GetData(string reportFolder, string reportName, string startDate, string endDate)
   {
       Console.WriteLine(reportFolder + reportName);
       testDoc = (busobj.Document)boApp.Documents.Open(reportFolder + reportName, true, false, null, null);

       //Report Start Date
       testDoc.Variables[1].Value = startDate;
       //Report End Date
       testDoc.Variables[2].Value = endDate;
       //Area. Needs to be a semi-colon delimited string
       testDoc.Variables[3].Value = "L;B;H;";

       testDoc.Refresh();

       return testDoc;

   }

   static void ExportData(string exportFolder, string exportFileName)
   {
       testDoc.Reports.get_Item(1).ExportAsText(exportFolder + exportFileName);
       //2 = DoNotSaveChanges
       testDoc.Close(2);
   }

}

我将BOApp的实例化移动到了RefreshBusinessObjects方法中,似乎可以解决这个问题

我也使用这个登录代码,它可以工作,但是需要点击BO登录diaglog的OK按钮。是否有一些方法可以跳过此单击按钮步骤?
