c# - 将 XML 发布到 URL

Question

我正在尝试发布XMLDocument到 URL。这是我到目前为止所拥有的：

   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其加载XmlDocument到WebRequest对象中，以便可以将其发布到该 URL。

您需要在这样调用之前写入 RequestStream req.GetResponse()。

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