C# XML反序列化与序列化

在C#中，可以用XmlSerializer类来反序列化与序列化xml，但我们也可以封装一下，可以使用起来更方便

1. 将XML字符串反序列化成对象 方法

/// <summary>
/// 将XML字符串反序列化成对象
/// </summary>
/// <typeparam name="T">返回的对象类型</typeparam>
/// <typeparam name="xml">xml字符串</typeparam>
/// <typeparam name="xmlRootName">xml根节点</typeparam>
/// <returns>返回对象类型</returns>
public static T Deserialize<T>(string xml, string xmlRootName = "Root")
{
    T result = default(T);
    using (StringReader sr = new StringReader(xml))
    {
        XmlSerializer xmlSerializer = string.IsNullOrWhiteSpace(xmlRootName) ?
            new XmlSerializer(typeof(T)) : new XmlSerializer(typeof(T), new XmlRootAttribute(xmlRootName));
        result = (T)xmlSerializer.Deserialize(sr);
    }
    return result;
}

2. 将XML文件反序列化成对象 方法

/// <summary>
/// 将XML文件反序列化成对象
/// </summary>
/// <typeparam name="T">返回的对象类型</typeparam>
/// <typeparam name="xml">文件路径</typeparam>
/// <typeparam name="xmlRootName">xml根节点</typeparam>
/// <returns>返回对象类型</returns>
public static T DeserializeFile<T>(string filePath, string xmlRootName = "Root")
{
    T result = default(T);
    if (File.Exists(filePath))
    {
        using (StreamReader reader = new StreamReader(filePath))
        {
            XmlSerializer xmlSerializer = string.IsNullOrWhiteSpace(xmlRootName) ?
                new XmlSerializer(typeof(T)) : new XmlSerializer(typeof(T), new XmlRootAttribute(xmlRootName));
            result = (T)xmlSerializer.Deserialize(reader);
        }
    }

    return result;
}

3. 将对象序列化成XML字符串 方法

/// <summary>
/// 将对象序列化成XML字符串
/// </summary>
/// <typeparam name="sourceObj">数据对象</typeparam>
/// <typeparam name="xmlRootName">xml根节点</typeparam>
/// <returns>xml字符串</returns>
public static string Serializer(object sourceObj, string xmlRootName = "Root")
{
    MemoryStream Stream = new MemoryStream();
    Type type = sourceObj.GetType();
    XmlSerializer xmlSerializer = string.IsNullOrWhiteSpace(xmlRootName) ?
        new XmlSerializer(type) : new XmlSerializer(type, new XmlRootAttribute(xmlRootName));
    xmlSerializer.Serialize(Stream, sourceObj);
    Stream.Position = 0;
    StreamReader sr = new StreamReader(Stream);
    string str = sr.ReadToEnd();
    sr.Dispose();
    Stream.Dispose();

    return str;
}

4. 将对象序列化成XML文件 方法

/// <summary>
/// 将对象序列化成XML文件
/// </summary>
/// <typeparam name="filePath">xml文件路径</typeparam>
/// <typeparam name="sourceObj">数据对象</typeparam>
/// <typeparam name="xmlRootName">xml根节点</typeparam>
public static void SerializerFile(string filePath, object sourceObj, string xmlRootName = "Root")
{
    if (!string.IsNullOrWhiteSpace(filePath) && sourceObj != null)
    {
        Type type = sourceObj.GetType();
        using (StreamWriter writer = new StreamWriter(filePath))
        {
            XmlSerializer xmlSerializer = string.IsNullOrWhiteSpace(xmlRootName) ?
                new XmlSerializer(type) : new XmlSerializer(type, new XmlRootAttribute(xmlRootName));

            xmlSerializer.Serialize(writer, sourceObj);
        }
    }
}
