我将一个json字符串集合从Android设备传递给.net MVC HttpPost方法。我的json字符串就像。
{"collection",[{"Name":"A","Age":"12","Class":"10"},{"Name":"B","Age":"12","Class":"10"}]}
我的MVC控制功能是:
[HttpPost]
public ActionResult Create(string[] collection)
{
try
{
// TODO: Add insert logic here
JavaScriptSerializer json_serializer = new JavaScriptSerializer();
List<Model.StudentBehaviour> stdbehaviour_list = Newtonsoft.Json.JsonConvert.DeserializeObject<List<Model.StudentBehaviour>>(collection);
Lib.StudentModule.StudentManager.InsertStudentBehaviours(stdbehaviour_list);
return Json("success", JsonRequestBehavior.AllowGet);
}
catch
{
return Json("exception", JsonRequestBehavior.AllowGet);
}
}
函数参数值为
collection = "(Collection)"
集合中的期望值是
collection[0]
Name = A
Age = 12
Class = 10
collection[1]
Name = B
Age = 12
Class = 10
请帮助解决此问题

ASP.NET MVC具有ModelBinding的概念。这意味着如果向Action方法添加参数,MVC将尝试使用您发送的数据填充这些参数。
这意味着您可以将代码更改为:
// Example of your Student class.
// Make sure that all properties you want to bind to are public
public class Student
{
public string Name { get; set; }
public int Age { get; set; }
public int Class { get; set; }
}
// Example of an Action method. Note that instead of taking a string as parameter,
// you just accept a collection of Student objects.
[HttpPost]
public JsonResult Create(List<Student> collection)
{
if (ModelState.IsValid)
{
return Json("success", JsonRequestBehavior.AllowGet);
}
else
{
return Json("exception", JsonRequestBehavior.AllowGet);
}
}
然后,您可以使用以下jquery发布您的数据:
function sendData() {
var data = [{ 'Name': 'A', 'Age': '12', 'Class': '10' },
{ 'Name': 'B', 'Age': '12', 'Class': '10' }];
var collection = JSON.stringify(data);
$.ajax({
url: "Home/Create",
type: "POST",
data: collection,
dataType: 'json',
contentType: 'application/json; charset=utf-8',
}).done(function (msg) {
alert("Data Saved: " + msg);
});
}
