C# 如何将对象序列化为XML

如何将.net对象序列化为XML，然后将其反序列化回来？

在VB.net中，您首先要向类添加一些属性（如果需要的话）

---

这可以通过对象和字符串扩展方法实现

using System.IO;
using System.Xml.Serialization;

namespace XmlExtensionMethods
{

/// <summary>
/// Provides extension methods useful for XML Serialization and deserialization.
/// </summary>
public static class XMLExtensions
{
    /// <summary>
    /// Extension method that takes objects and serialized them.
    /// </summary>
    /// <typeparam name="T">The type of the object to be serialized.</typeparam>
    /// <param name="source">The object to be serialized.</param>
    /// <returns>A string that represents the serialized XML.</returns>
    public static string SerializeXML<T>(this T source) where T : class, new()
    {
        source.CheckNull("Object to be serialized.");

        var serializer = new XmlSerializer(typeof(T));
        using (var writer = new StringWriter())
        {
            serializer.Serialize(writer, source);
            return writer.ToString();
        }
    }


/// <summary>
    /// Extension method to string which attempts to deserialize XML with the same name as the source string.
    /// </summary>
    /// <typeparam name="T">The type which to be deserialized to.</typeparam>
    /// <param name="XML">The source string</param>
    /// <returns>The deserialized object, or null if unsuccessful.</returns>
    public static T DeserializeXML<T>(this string XML) where T : class, new()
    {
        XML.CheckNull("XML-string");

        var serializer = new XmlSerializer(typeof(T));
        using (var reader = new StringReader(XML))
        {
            try { return (T)serializer.Deserialize(reader); }
            catch { return null; } // Could not be deserialized to this type.
        }
    }
}

}
}

使用System.IO；
使用System.Xml.Serialization；
命名空间XmlExtensionMethods
{
/// 
///提供对XML序列化和反序列化有用的扩展方法。
/// 
公共静态类XMLExtensions
{
/// 
///获取对象并将其序列化的扩展方法。
/// 
///要序列化的对象的类型。
///要序列化的对象。
///表示序列化XML的字符串。
公共静态字符串序列化XML（此T源），其中T:class，new（）
{
CheckNull（“要序列化的对象”）；
var serializer=newxmlserializer（typeof（T））；
使用（var writer=new StringWriter（））
{
serializer.Serialize（writer，source）；
返回writer.ToString（）；
}
}
/// 
///尝试反序列化与源字符串同名的XML的字符串扩展方法。
/// 
///要反序列化到的类型。
///源字符串
///反序列化对象，如果不成功，则为null。
公共静态T反序列化XML（此字符串XML），其中T:class，new（）
{
CheckNull（“XML字符串”）；
var serializer=newxmlserializer（typeof（T））；
使用（var reader=newstringreader（XML））
{
尝试{return（T）serializer.Deserialize（reader）；}
无法将catch{return null；}//反序列化为此类型。
}
}
}
}
}

您可以这样使用它：

string savestring;

public void Save()
{
     savestring = mySerializableObject.SerializeXML<MySerializableClass>();
}

public void Load()
{
     mySerializableObject  = savestring.DeserializeXML<MySerializableClass>();
}

string保存字符串；
公共作废保存（）
{
savestring=mySerializableObject.SerializeXML（）；
}
公共空荷载（）
{
mySerializableObject=savestring.DeserializeXML（）；
}

注：我不认为这些扩展方法有什么好处。

VB.NET

using System.IO;
using System.Xml.Serialization;

namespace XmlExtensionMethods
{

/// <summary>
/// Provides extension methods useful for XML Serialization and deserialization.
/// </summary>
public static class XMLExtensions
{
    /// <summary>
    /// Extension method that takes objects and serialized them.
    /// </summary>
    /// <typeparam name="T">The type of the object to be serialized.</typeparam>
    /// <param name="source">The object to be serialized.</param>
    /// <returns>A string that represents the serialized XML.</returns>
    public static string SerializeXML<T>(this T source) where T : class, new()
    {
        source.CheckNull("Object to be serialized.");

        var serializer = new XmlSerializer(typeof(T));
        using (var writer = new StringWriter())
        {
            serializer.Serialize(writer, source);
            return writer.ToString();
        }
    }


/// <summary>
    /// Extension method to string which attempts to deserialize XML with the same name as the source string.
    /// </summary>
    /// <typeparam name="T">The type which to be deserialized to.</typeparam>
    /// <param name="XML">The source string</param>
    /// <returns>The deserialized object, or null if unsuccessful.</returns>
    public static T DeserializeXML<T>(this string XML) where T : class, new()
    {
        XML.CheckNull("XML-string");

        var serializer = new XmlSerializer(typeof(T));
        using (var reader = new StringReader(XML))
        {
            try { return (T)serializer.Deserialize(reader); }
            catch { return null; } // Could not be deserialized to this type.
        }
    }
}

}
}

Public Shared Function SerializeObj(obj As Object) As String
    Dim xs As New System.Xml.Serialization.XmlSerializer(obj.GetType)
    Dim w As New IO.StringWriter
    xs.Serialize(w, obj)
    Return w.ToString
End Function

往回看有点复杂，您需要声明一个xml文档并从中提取数据

您可以查看此链接，它可能会帮助您解答所有问题。谢谢

Public Shared Function SerializeObj(obj As Object) As String
    Dim xs As New System.Xml.Serialization.XmlSerializer(obj.GetType)
    Dim w As New IO.StringWriter
    xs.Serialize(w, obj)
    Return w.ToString
End Function
