c# - 在哪里使用 XmlWriter 编写 XML 以在 ASP.NET 中通过 HttpWebRequest POST 发送？

Question

这是我的代码，请参阅说明 ???在这里做什么??? 我不确定我将这个 XML 写到哪里以便能够通过那里的 objRequest 在我的 POST 中发送它......

string project_id = context.Request.QueryString["project"];
string person_id = context.Request.QueryString["person"];
string post_date = context.Request.QueryString["date"];
string post_hours = context.Request.QueryString["hours"];
string case_num = context.Request.QueryString["case"];


HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create("http://company.updatelog.com/projects/" + project_id + "/time_entries.xml");

objRequest.Method = "POST";

objRequest.ContentType = "application/xml";

XmlWriterSettings settings = new XmlWriterSettings();
settings.Indent = true;
settings.IndentChars = ("    ");


using (XmlWriter writer = XmlWriter.Create(?????WHAT TO DO HERE????, settings))
{
    writer.WriteStartElement("time-entry");
    writer.WriteElementString("person-id", person_id);
    writer.WriteElementString("date", post_date);
    writer.WriteElementString("hours", post_hours);
    writer.WriteElementString("description", "Worked on Case #" + case_num);
    writer.WriteEndElement();
}


StreamWriter myWriter = null;


try
{

    myWriter = new StreamWriter(objRequest.GetRequestStream());

    myWriter.Write(post_xml);

}

catch (Exception e)
{

    context.Response.Write(e.Message);

}

finally
{

    myWriter.Close();

}

Answer 1

XmlWriter writer = XmlWriter.Create(objRequest.GetRequestStream(), settings);

那时您不需要创建 StreamWriter。您在 XmlWriter 中写入的内容将写入 requestStream。

Answer 2

您可以只使用一个 XmlTextWriter，它采用一个基本上只是将其写入内存的字符串构建器。

代码：

var buidler = new StringBuilder();
var writer = XmlWriter.Create(builder);
