将序列化的 XML 写入字符串并在浏览器中显示

Question

我有一个需要作为加密 XML 字符串发送的序列化对象。我能够将序列化对象保存到格式良好的 XML 文件中，但这不是我想要的。我已经让 Rijndael 加密/解密为示例字符串工作。

Person person = new Person("Irish", "Chieftain");
XmlSerializer xmlSerializer = new XmlSerializer(typeof(Person));

// Write serialized XML to file
System.Guid guid = System.Guid.NewGuid();
StreamWriter streamWriter 
    = new StreamWriter(@"C:\application" + "_" + guid.ToString() + ".xml")
xmlSerializer.Serialize(streamWriter.BaseStream, person);

我希望能够在浏览器中显示 XML 字符串，在加密之前，测试是否将正确的加密字符串发送到另一台机器上的解密方法。

我已经讨论了一周，并查看了关于 SO 的其他答案，例如： How to return XML in ASP.NET?

谁能告诉我在浏览器中将生成的 XML 显示为字符串的正确语法？

[更新] 这是我试图呈现 XML 的内容：

MemoryStream memoryStream = new MemoryStream();
XmlTextWriter xmlWriter2 = new XmlTextWriter(memoryStream, Encoding.UTF8); 
xmlWriter2.Formatting = Formatting.Indented;
xmlSerializer.Serialize(xmlWriter2, person);
memoryStream = (MemoryStream) xmlWriter2.BaseStream;
UTF8Encoding encoding2 = new UTF8Encoding();
stringData = encoding2.GetString(memoryStream.ToArray());
Response.ContentType = "text/xml";
Response.Write(stringData);

如果我删除“text/xml”内容类型，当我查看源代码时会得到以下信息（正确吗？）：

<?xml version="1.0" encoding="utf-8"?>
<Person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <FirstName>Irish</FirstName>
  <SecondName>Chieftain</SecondName>
</Person>

工作版本：

            #region Display original string
            // Write serialized XML to a string - Display purposes.
            MemoryStream memoryStream = new MemoryStream();
            XmlTextWriter xmlWriter2 
                = new XmlTextWriter(memoryStream, Encoding.UTF8);
            xmlWriter2.Formatting = Formatting.Indented;
            xmlSerializer.Serialize(xmlWriter2, person);
            memoryStream = (MemoryStream) xmlWriter2.BaseStream;
            UTF8Encoding encoding2 = new UTF8Encoding();
            stringData = encoding2.GetString(memoryStream.ToArray());

            Response.Clear();
            Response.ContentType = "text/xml";
            Response.Cache.SetCacheability(HttpCacheability.NoCache);
            Response.Cache.SetAllowResponseInBrowserHistory(true);
            Response.Write(stringData);
            Response.End();
            #endregion

Answer 1

对 XML 字符串进行 HtmlEncoding 也可以解决问题。

Response.Write(HttpUtility.HtmlEncode(stringData));

Answer 2

您很可能需要在 Response 对象上设置ContentType。这对应于 MIME 类型。对于 xml，它应该是 text/xml
