Outlook VSTO C# 发布到 html url

Question

我正在使用 VS2010 C# 为 Outlook 2010 制作插件。

我的插件的目的是从新电子邮件中获取 To、CC、BC 从功能区按下自定义按钮并将其发布到外部 URL（其中 接受一个帖子请求）。类似于 html/jsp 中的表单如何将输入发布到 不同的页面（网址）。

到目前为止，我可以获取 To、CC、BC 并将其存储在字符串变量中。但我不 知道如何向外部网址发帖。

任何帮助将不胜感激。谢谢。

到目前为止，这是我的函数代码：

public void makePost(object Item, ref bool Cancel)
{
    Outlook.MailItem myItem = Item as Outlook.MailItem;

    if (myItem != null)
    {
        string emailTo = myItem.To;
        string emailCC = myItem.CC;
        string emailBCC = myItem.BCC;

        if (emailTo == null && emailCC == null && emailBCC == null)
        {
            MessageBox.Show("There are no recipients to check.");
        }
        else
        {
            string emailAdresses = string.Concat(emailTo, "; ", emailCC, "; ", emailBCC);

            //do something here to post the string(emailAddresses) to some url.
        }
    }
}

你需要使用WebRequest/HttpWebRequest类，例如：

HttpWebRequest request = HttpWebRequest.Create("http://google.com/postmesmth") as HttpWebRequest;
request.Method = WebRequestMethods.Http.Post;
request.Host = "google.com";
request.UserAgent = "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:22.0) Gecko/20100101 Firefox/22.0";
string data = "myData=" + HttpUtility.UrlEncode("Hello World!");


StreamWriter writer = new StreamWriter(request.GetRequestStream());
writer.Write(data);
writer.Close();

HttpWebResponse response = request.GetResponse() as HttpWebResponse;
