MVC中返回Json的几种声明方式

第一种，单行数据

 

var result = new { name = "linfei", age = "26", address = "wuhan" };


//MVC中返回

return Json(result);


//asp.net中返回

System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();

return js.Serialize(result);

 

显示结果：

{

    "name": "linfei",

    "age": "26",

    "address": "wuhan"

}

 

第二种，多行数据

 

var result = new object[] { new { name = "linfei", age = "22", address = "wuhan" }, new { name = "linfei", arg = "26", address = "sh" } };


//MVC中返回

return Json(result);


//asp.net中返回

System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();

return js.Serialize(result);

 

显示结果：

 

[

    {

        "name": "linfei",

        "age": "22",

        "address": "wuhan"

    },

    {

        "name": "linfei",

        "arg": "26",

        "address": "sh"

    }

]

 

 

第三种，多行多对象数据

 

var data1 = new object[] { new { name = "linfei", age = "22", address = "wuhan" }, new { name = "linfei", arg = "26", address = "sh" } };

var data2 = new object[] { new { test="123",test1="qq"}, new { test = "456", test1 = "ww" } };

var result = new object[] { new { rows = data1 }, new { header = data2 } };

//MVC中返回

return Json(result);

//asp.net中返回

System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();

return js.Serialize(result);

 

 显示结果：

 

[

    {

        "rows": [

            {

                "name": "linfei",

                "age": "22",

                "address": "wuhan"

            },

            {

                "name": "linfei",

                "arg": "26",

                "address": "sh"

            }

        ]

    },

    {

        "header": [

            {

                "test": "123",

                "test1": "qq"

            },

            {

                "test": "456",

                "test1": "ww"

            }

        ]

    }

]

 

 

 还有个asp.net中的写法，网上找的

var data1 = new object[] { new { name = "linfei", age = "22", address = "wuhan" }, new { name = "linfei", arg = "26", address = "sh" } };

var data2 = new object[] { new { test = "123", test1 = "qq" }, new { test = "456", test1 = "ww" } };

Newtonsoft.Json.JsonSerializerSettings settings = new Newtonsoft.Json.JsonSerializerSettings();

settings.ReferenceLoopHandling = Newtonsoft.Json.ReferenceLoopHandling.Ignore;

string result = Newtonsoft.Json.JsonConvert.SerializeObject(new { rows = data1, header = data2 }, Newtonsoft.Json.Formatting.Indented, settings);
