如何爲CData屬性？

Question

我如何使用CData序列化一個屬性？我已經嘗試了幾種不同的方法，包括使原始屬性XmlIgnore和引入返回XmlCDataSection的屬性。目前爲止沒有任何工作。

我有以下runnable控制檯測試顯示錯誤。我如何修改這個以允許正則表達式數據序列化和反序列化。

using System; 
using System.Collections.Generic; 
using System.Linq; 

namespace ConsoleApplication1 
{ 
    using System.Diagnostics; 
    using System.IO; 
    using System.Threading; 
    using System.Xml; 
    using System.Xml.Serialization; 

    [Serializable] 
    public class MyRegex 
    { 
     public string Regex { get; set; } 
    } 
    public static class SerializerHelper<T> 
    { 
     public static string Serialize(T myobject) 
     { 
      XmlSerializer xmlSerializer = new XmlSerializer(typeof(T)); 
      StringWriter stringWriter = new StringWriter(); 
      xmlSerializer.Serialize(stringWriter, myobject); 
      string xml = stringWriter.ToString(); 

      XmlDocument xmlDoc = new XmlDocument(); 
      xmlDoc.LoadXml(xml); 
      StringWriter sw = new StringWriter(); 
      XmlTextWriter xw = new XmlTextWriter(sw); 
      xmlDoc.WriteTo(xw); 

      return sw.ToString(); 
     } 
     public static T DeSerialize(string xml) 
     { 
      XmlSerializer xmlSerializer = new XmlSerializer(typeof(T)); 
      StringReader stringReader = new StringReader(xml); 
      return (T)xmlSerializer.Deserialize(stringReader); 
     } 
    } 
    class Program 
    { 
     static void Main(string[] args) 
     { 
      MyRegex original = new MyRegex { Regex = "\b[1-3]{1}\b#Must be a value of 1 to 3" }; 
      string xml = SerializerHelper<MyRegex>.Serialize(original); 
      Console.WriteLine("--- SERIALIZE ---"); 
      Console.WriteLine(xml); 
      Console.WriteLine(); 
      Console.WriteLine(); 


      Console.WriteLine("--- DESERIALIZE ---"); 
      MyRegex deSerial = SerializerHelper<MyRegex>.DeSerialize(xml); 
      Console.WriteLine("Equals? " + (deSerial.Regex.Equals(original.Regex))); 

      Console.WriteLine(); 
      Console.WriteLine(); 
      Console.WriteLine("Console.ReadKey();"); 
      Console.ReadKey(); 
     } 
    } 
} 

附加：試圖更換方法 - 不工作

private string _regex; 
    public string Regex 
    { 
     get { return _regex.Replace(@"\\", @"\").Replace("&amp;", "&").Replace("&lt;", "<").Replace("&gt;", ">").Replace("&quot;", "\"").Replace("&apos;", "'"); } 
     set { _regex = value.Replace(@"\", @"\\").Replace("&", "&amp;").Replace("<", "&lt;").Replace(">", "&gt;").Replace("\"", "&quot;").Replace("'", "&apos;"); } 
    }

你不需要在這裏使用CData的 - 問題是，你的正則表達式沒有字符串「\ B」，它具有\ u0008（BS）字符 - 這不是正則表達式中所需的。如果你逃跑的「\」在MyRegex初始化，它應該工作：

MyRegex original = new MyRegex { Regex = "\\b[1-3]{1}\\b#Must be a value of 1 to 3" }; 

這個控制檯應用程序就可以運行，而且將數據串行化精細（使用\ B）：

public class StackOverflow_6755014 
{ 
    public class MyRegex 
    { 
     public string Regex { get; set; } 
    } 
    public static class SerializerHelper<T> 
    { 
     public static string Serialize(T myobject) 
     { 
      XmlSerializer xmlSerializer = new XmlSerializer(typeof(T)); 
      StringWriter stringWriter = new StringWriter(); 
      xmlSerializer.Serialize(stringWriter, myobject); 
      string xml = stringWriter.ToString(); 

      XmlDocument xmlDoc = new XmlDocument(); 
      xmlDoc.LoadXml(xml); 
      StringWriter sw = new StringWriter(); 
      XmlTextWriter xw = new XmlTextWriter(sw); 
      xmlDoc.WriteTo(xw); 

      return sw.ToString(); 
     } 
     public static T DeSerialize(string xml) 
     { 
      XmlSerializer xmlSerializer = new XmlSerializer(typeof(T)); 
      StringReader stringReader = new StringReader(xml); 
      return (T)xmlSerializer.Deserialize(stringReader); 
     } 
    } 
    public static void Test() 
    { 
     MyRegex original = new MyRegex { Regex = "\\b[1-3]{1}\\b#Must be a value of 1 to 3" }; 
     string xml = SerializerHelper<MyRegex>.Serialize(original); 
     Console.WriteLine("--- SERIALIZE ---"); 
     Console.WriteLine(xml); 
     Console.WriteLine(); 
     Console.WriteLine(); 


     Console.WriteLine("--- DESERIALIZE ---"); 
     MyRegex deSerial = SerializerHelper<MyRegex>.DeSerialize(xml); 
     Console.WriteLine("Equals? " + (deSerial.Regex.Equals(original.Regex))); 

     Console.WriteLine(); 
     Console.WriteLine(); 
     Console.WriteLine("Console.ReadKey();"); 
     Console.ReadKey(); 
    } 
}
