Question

你好我已经创建了一个应用程序，它将查看并查看工厂运行了多少小时，并且旨在向负责跟踪这些工厂的所有污染物的人发送电子邮件。我的问题是，虽然它部署到机器后它在Visual Studio中工作，但它给了我一个错误。

如果有人可以查看代码并告诉我哪里有错误。非常感谢。

首先，我注意到以下几行代码：

Outlook.Application oLook = new Outlook.Application();
oLook.Quit();

您需要使用Outlook Application类的现有实例来调用Quit方法，而不是创建一个新方法。

我的问题是，当我在Visual Studio中部署到机器时，它会发生错误。

您会收到标准的安全提示。在此上下文中的“安全性”是指所谓的“对象模型防护”，它触发安全提示并阻止对某些功能的访问，以防止恶意程序从Outlook数据中收集电子邮件地址并使用Outlook传播病毒和垃圾邮件。不能简单地关闭这些提示。有三种主要方法可以避免这种提示：

Security Manager for Outlook组件允许在运行时关闭/打开提示。
使用不生成安全提示的低级代码。或围绕该API的任何其他第三方包装（例如，Redemption）。
运行最新的防病毒软件。

您可以在Outlook "Object Model Guard" Security Issues for Developers文章中详细了解相关内容。
