在 ASP.NET 中，在哪里使用 XmlWriter 编写 XML 以通过 HttpWebRequest POST 发送？

Question

这是我的代码，请参阅“???在这里做什么???”的部分 我不确定我将该 XML 写入何处，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

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

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

Answer 2

您可以只使用 XmlTextWriter，它采用字符串生成器，基本上只是将其写入内存。

代码：

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