一起谈.NET技术，如何将XML与OBJECT进行相互转换（泛型以及通用方法）

还有就是对于MVC3，Razor实在太给力了，扔掉MVC2吧，哈哈，@确实挺不错的。

　　在ORMCodeHelper中，对于配置文件的使用的思路还是不错的，哥学以致用，提炼个泛型的出来（其实最主要的还是插件开发的架构）。对于XML与OBJECT的转换来说，下面讲的是一种Serialize方法。其实哥还有另外一种通过反射将XML转换成对象的方法，不过，涉及到公司****，那种方法还是不写了。当然，那种方法哥是可以横着写了（因为哥早就背在心里了），哈哈，通用的代码....

　　先看代码，如下：

    public static class Serializer

    {

        public static void Serialize<T>(string filePath, T[] array)  where T:new()

        {

            if (string.IsNullOrEmpty(filePath)||

                array == null||array.Length==0)

            {

                return;

            }

            try

                XmlSerializerFactory xmlSerializerFactory = new XmlSerializerFactory();

                XmlSerializer xmlSerializer =

                    xmlSerializerFactory.CreateSerializer(array.GetType(), typeof(T).Name);

                Stream stream = new FileStream(filePath, FileMode.Create);

                xmlSerializer.Serialize(stream, array);

                stream.Close();

            catch

        }

        public static void Serialize(string filePath, object obj)

            if (string.IsNullOrEmpty(filePath) || obj == null)

                    xmlSerializerFactory.CreateSerializer(obj.GetType(), obj.GetType().Name);

                xmlSerializer.Serialize(stream, obj);

    }

        public static List<T> Deserialize<T>(string filePath)  where T:new()

            List<T> results=new List<T>();

            if (string.IsNullOrEmpty(filePath)||!File.Exists(filePath))

                return results;

            object obj = null;

                    xmlSerializerFactory.CreateSerializer(typeof(T[]), typeof(T).Name);

                Stream stream = new FileStream(filePath, System.IO.FileMode.Open);

                obj = xmlSerializer.Deserialize(stream);

                results.AddRange(obj as T[]);

            return results;

        public static object Deserialize(string filePath, Type targetType)

            if (string.IsNullOrEmpty(filePath)||!File.Exists(filePath)

                || targetType == null)

                return null;

                    xmlSerializerFactory.CreateSerializer(targetType, targetType.Name);

                Stream stream = new FileStream(filePath, FileMode.Open);

            return obj;

　　从上面4个方法，可以看出主要是通过XmlSerializer将对象序列化为XML以及将XML反序列化为对象，这种方法比较简单，而且易用。

　　（一）Serialize<T>(string filePath, T[] array)，Deserialize<T>(string filePath)

　　通过单元测试来看看Serialize<T>(string filePath, T[] array)方法生成的XML内容，先注释掉//DeleteFile(filePath);

public void SerializeTestHelper(AppSetting[] inputs)

            AppSetting[] settings = inputs;

            string filePath = @"d:\" + typeof(AppSetting).Name + ".config";

            Serializer.Serialize<AppSetting>(filePath, settings);

            List<AppSetting> results = Serializer.Deserialize<AppSetting>(filePath);

            int length = results.Count;

            Assert.IsTrue(length == settings.Length);

            for (int index = 0; index < length; index++)

                Assert.IsTrue(results[index].Value == settings[index].Value);

                Assert.IsTrue(results[index].Key == settings[index].Key);

                Assert.IsTrue(results[index].Author == settings[index].Author);

            //DeleteFile(filePath);

　　生成的XML如下：

<?xml version="1.0"?>

  <AppSetting>

    <Key>key0</Key>

    <Value>value0</Value>

    <Author>author0</Author>

  </AppSetting>

    <Key>key1</Key>

    <Value>value1</Value>

    <Author>author1</Author>

    <Key>key2</Key>

    <Value>value2</Value>

    <Author>author2</Author>

</ArrayOfAppSetting>

　　从上面的单元测试可以看出：通过Serialize<T>(string filePath, T[] array)方法将对象数组生成XML内容，可以通过Deserialize<T>(string filePath)将XML内容转换成相应的对象数组，内容相一致。

　　（二）Serialize(string filePath, object obj)，Deserialize(string filePath, Type targetType)

　　通过单元测试来看看Serialize(string filePath, object obj)方法生成的XML内容，先注释掉//DeleteFile(filePath);

private static void SerializeTestHelper()

            AppSetting setting = new AppSetting()

                Author = "AuthorTest",

                Key = "KeyTest",

                Value = "ValueTest"

            };

            Serializer.Serialize(filePath, setting);

            AppSetting result = Serializer.Deserialize(filePath, typeof(AppSetting)) as AppSetting;

            Assert.IsTrue(result.Value == setting.Value);

            Assert.IsTrue(result.Author == setting.Author);

            Assert.IsTrue(result.Key == setting.Key);

  <Key>KeyTest</Key>

  <Value>ValueTest</Value>

  <Author>AuthorTest</Author>

</AppSetting>

　　从上面的单元测试可以看出：通过Serialize(string filePath, object obj)方法将对象生成XML内容，可以通过Deserialize(string filePath, Type targetType)将XML内容转换成相应的对象，内容相一致。其中，object也可以是对象数组的，这个留给读者自己去验证。

　　测试都是可以通过的，这里仅仅是验证正确的功能，如下图:
