我创建了一个web服务，可以从Global.cs自动发送电子邮件。我使用了参考代码项目参考模拟WS

为自动安排的电子邮件服务，它是发送电子邮件每2分钟从我的gmail帐户到另一个gmail帐户。现在，我想在这次成功的基础上走得更远。我想有用户界面，用户可以选择谁发送，开始日期和结束日期在网络形式，使他们的工作。

用户可以从列表框中选择发送对象和开始/结束日期。然后，用户可以设置为每日发送邮件。我已经为用户名、用户电子邮件、开始日期和结束日期创建了一个表。我不知道如何链接输入从这个GUI到Global.cs。有什么想法吗?我还想确保服务应该在结束日期停止运行。请adivse。这是我的自动邮件服务代码。

如何集成自动安排的电子邮件服务与用户界面asp .net

要做的第一件事是在Global.cs类文件中添加一些更多的字段。它将处理用户将使用的值。

private string Recipient;
private DateTime StartTime;
private DateTime EndTime;

…如果你想添加更多的字段，你可以添加更多的字段，等等。

然后您可以使用表单来填充POST请求中的这些字段，如下所示

if(IsPost) {
   // get the form items and add details to the Global.cs
}

一旦您完成了添加细节，执行您已经拥有的函数并从Global.cs中添加细节。
