我们正在实施使用

下载Gmail A.C附件的代码

openpop3命名空间。在此代码中，我们正在检查附件大小（如果附件）

size大于指定值（在kb中配置文件中设置的值）。然后它必须

向发件人发送电子邮件.... 它在Windows应用程序中工作正常，但每当我实现代码

在Window服务中遇到问题。它从这行代码退出函数

OpenPop.Mime.Message m = popClient.GetMessage(i);

框架：3.5 V.S：2008 语言＃打开POP命名空间V2.0.4.369

This is my code

 OpenPop.Mime.Message m = popClient.GetMessage(i);

            popClient.Authenticate(username, password);
            int Count = popClient.GetMessageCount();
            writeToLogFile("Total Mail count is:" + Count.ToString());
            if (Count > 0)
            {
                for (int i = 1; i <= Count; i++)
                {

谢谢@Antonio Bakula我在我的Windows服务应用程序中写了try catch块并记录它。然后我理解了我的bug并且它给了异常，无法读取消息，另一个实例已经在阅读。这是因为代码是基于计时器的

我每隔1分钟开火一次。现在我添加了代码，一旦它启动电子邮件处理就停止计时器，并在完成电子邮件处理代码后启动计时器。

OpenPop的Windows服务从GetMessage代码退出，相同的代码OK win app
