Question

我正在尝试开发一个通过outlook和interop服务发送自动电子邮件并获得以下异常的应用程序。下面是有例外的代码。

 try
     {
       Microsoft.Office.Interop.Outlook.Application app = new Microsoft.Office.Interop.Outlook.Application();
      Microsoft.Office.Interop.Outlook.MailItem mailItem = (Outlook.MailItem)app.CreateItem(Outlook.OlItemType.olMailItem);
     mailItem.Subject = "Details of Subject";
     mailItem.To = "example@gmail.com";
     mailItem.Body = "Automated email testing"
     // mailItem.Attachments.Add(logPath);//logPath is a string holding path to the log.txt file
     mailItem.Importance = Outlook.OlImportance.olImportanceHigh;
     mailItem.Display(false);
     mailItem.Send();
 }
catch (Exception ex)
  {
         WriteErrorLog("\n");
         WriteErrorLog(ex.Message);
         WriteErrorLog(ex.StackTrace);
}

它抛出异常：

System.Runtime.Remoting.RemotingServices.AllocateUninitializedObject(RuntimeType objectType) at System.Runtime.Remoting.Activation.ActivationServices.CreateInstance(RuntimeType serverType) at System.Runtime.Remoting.Activation.ActivationServices.IsCurrentContextOK(RuntimeType serverType, Object[] props, Boolean bNewObj)

第120行是第一行app = new Microsoft.Office.Interop.Outlook.Application（）;

尝试从后台流程关闭Outlook。然后执行你的代码。

创建Windows服务以通过outlook com interop发送自动电子邮件
