c# - 将 XML 发布到 URL

Question

我正在尝试将 XMLDocument 发布到 URL。这是我目前所拥有的:

   var uri = System.Configuration.ConfigurationManager.AppSettings["Url"];
   var template = System.Configuration.ConfigurationManager.AppSettings["Template"];
   XmlDocument reqTemplateXml = new XmlDocument();
   reqTemplateXml.Load(template);

   reqTemplateXml.SelectSingleNode("appInfo/appNumber").InnerText = x; 
   reqTemplateXml.SelectSingleNode("appInfo/coappNumber").InnerText = y;

   WebRequest req = null;
   WebResponse rsp = null;
   req = WebRequest.Create(uri);
   req.Method = "POST";
   req.ContentType = "text/xml";
   rsp = req.GetResponse();

我想弄清楚的是如何将此 XmlDocument 加载到 WebRequest 对象，以便它可以发布到该 URL。

在像这样调用 req.GetResponse() 之前，您需要写入 RequestStream。

    using (var writer = new StreamWriter(req.GetRequestStream()))
    {
        writer.Write(xml);
    }
