C#将对象序列化成JSON字符串
public string GetJsonString() { List<Product> products = new List<Product>(){ new Product(){Name="苹果",Price=5.5}, new Product(){Name="橘子",Price=2.5}, new Product(){Name="干柿子",Price=16.00} }; ProductList productlist = new ProductList(); productlist.GetProducts = products; return new JavaScriptSerializer().Serialize(productlist)); } public class Product { public string Name { get; set; } public double Price { get; set; } } public class ProductList { public List<Product> GetProducts { get; set; } }这里主要是使用JavaScriptSerializer来实现序列化操作，这样我们就可以把对象转换成Json格式的字符串，生成的结果如下：
{"GetProducts":[{"Name":"苹果","Price":5.5},{"Name":"橘子","Price":2.5},{"Name":"柿子","Price":16}]}
如何将Json字符串转换成对象使用呢？
在实际开发中，经常有可能遇到用JS传递一个Json格式的字符串到后台使用，如果能自动将字符串转换成想要的对象，那进行遍历或其他操作时，就方便多了。那具体是如何实现的呢？
public static List<T> JSONStringToList<T>(this string JsonStr) { JavaScriptSerializer Serializer = new JavaScriptSerializer(); List<T> objs = Serializer.Deserialize<List<T>>(JsonStr); return objs; } public static T Deserialize<T>(string json) { T obj = Activator.CreateInstance<T>(); using (MemoryStream ms = new MemoryStream(Encoding.UTF8.GetBytes(json))) { DataContractJsonSerializer serializer = new DataContractJsonSerializer(obj.GetType()); return (T)serializer.ReadObject(ms); } } string JsonStr = "[{Name:'苹果',Price:5.5},{Name:'橘子',Price:2.5},{Name:'柿子',Price:16}]"; List<Product> products = new List<Product>(); products = JSONStringToList<Product>(JsonStr); foreach (var item in products) { Response.Write(item.Name + ":" + item.Price + "<br />"); } public class Product { public string Name { get; set; } public double Price { get; set; } }在上面的例子中，可以很方便的将Json字符串转换成List对象，操作的时候就方便多了~
