我曾經不止一次（當然不僅僅是我意識到這個問題）說到過，XML標准中的Namespace的設計其實是一個較為失敗的設計，它有它的優點，但缺點更多。

這里又有一個范例。我們需要在XML序列化的時候，更加小心地注意namespace的問題。
下面有一個例子程序
-
數據實體模型（這個類是通過xsd工具自動生成的，具體用途這里就不做展開了

實際對應的XML文檔應該是下面這樣的。注意，下面有一個my的命名空間。
<?xml version="1.0" encoding="UTF-8"?><?mso-infoPathSolution solutionVersion="1.0.0.3" productVersion="15.0.0" PIVersion="1.0.0.0" href="file:///C:\Users\chenxizhang\AppData\Local\Microsoft\InfoPath\Designer4\46fec1056ed24f25\manifest.xsf" ?><?mso-application progid="InfoPath.Document" versionProgid="InfoPath.Document.4"?><my:myFields xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2014-08-15T22:37:24" xml:lang="en-us">
<my:Title>test</my:Title>
</my:myFields>

為了使得XML序列化的時候，正常地生成這樣的一份文檔。我們需要做如下的特殊設計
using System;
using System.IO;
using System.Xml.Serialization;
namespace ConsoleApplication1
{
class Program
{
static void Main(string[] args)
{
//1.准備數據
var data = new myFields() { Title = "CEO" };
//2.准備命名空間
var ns = new XmlSerializerNamespaces();
ns.Add("my", "http://schemas.microsoft.com/office/infopath/2003/myXSD/2014-08-15T22:37:24");
//3.准備序列化器
var serializer = new XmlSerializer(typeof(myFields));
//4.准備用來接收的內存流
var ms = new MemoryStream();
//5.執行序列化
serializer.Serialize(ms, data, ns);
//6.將內容讀取出來
var reader = new StreamReader(ms);
ms.Position = 0;
Console.WriteLine(reader.ReadToEnd());
//7.關閉流
reader.Close();
ms.Close();
Console.Read();
}
}
}
不太難，但是確實是多了些步驟，不是嗎
