再谈Jquery Ajax方法传递到action

假设 controller中的方法是如下：
public ActionResult ReadPerson(PersonModel model)
        {
            string s = model.ToString();
            return Content(s);
        }

public ActionResult ReadPersons(List<PersonModel> model)
        {
            string result = "";
            if (model == null) return Content(result);
            foreach (var s in model)
            {
                result += s.ToString();
                result += "-------------";
            }
            return Content(result);
        }
其中PersonModel定义如下：
public class PersonModel
    {
        public int id
        {
            set;
            get;
        }
        public string name
        {
            set;
            get;
        }

        public int age
        {
            set;
            get;
        }

        public bool gender
        {
            set;
            get;
        }
        public string city
        {
            set;
            get;
        }

        public override string ToString()
        {
            string s = string.Format(@"id:{0}
name:{1}
age:{2}
gender:{3}
city:{4}
", id, name, age, gender, city);
            return s;
        }
    }
那么controller方法分别接受单个model和一个model的List。采用通过ajax传递参数。
对于传递单个参数的情况,假设js代码如下：
var person = {
               id: "001",
               name: "zhangsan",
               age: "20",
               gender: true,
               city: "shanghai"
           };

var option = {
               url: '/test/ReadPerson',
               type: 'POST',
               data: person,
               dataType: 'html',
               success: function (result) { alert(result); }
           };
$.ajax(option);
从chrome中截图可以看到如下：
传递的数据是一串Form数据，根据命名匹配的原则，也是可以取得数据的。
将option 的代码改成如下
var option = {
               url: '/test/ReadPerson',
               type: 'POST',
               data: JSON.stringify(person),
               dataType: 'html',
               success: function (result) { alert(result); }
           };
$.ajax(option);
其中JSON.stringify方法签名为 stringify ( value [ , replacer [ , space ] ] )，根据ECMA-262标准stringify 函数返回的是JSON格式的字符串。它可以有3个参数。摘抄如下：
The stringify function returns a String in JSON format representing an ECMAScript value. It can take three parameters. The first parameter is required. The value parameter is an ECMAScript value, which is usually an object or array, although it can also be a String, Boolean, Number or null. The optional replacer parameter is either a function that alters the way objects and arrays are stringified, or an array of Strings and Numbers that acts as a white list for selecting the object properties that will be stringified. The optional space parameter is a String or Number that allows the result to have white space injected into it to improve human readability.
默认的ContentType的属性值是"application/x-www-form-urlencoded"

因此，传递到controller的是一个json字符串，MVC根据命名匹配也是可以获得到参数的值。
将将option 的代码改成如下
var option = {
                url: '/test/ReadPerson',
                type: 'POST',
                data: person,
