推荐答案

http发布到asp.net mvc控制器这里是json数据示例


var postdata =
{

电子邮件：[e-mail]，
selectedanswer：{0：3,1：2,2：0,3：3,4： 1}
};


angular js code

http post to asp.net mvc controller here is json data example var postdata = { Email: "[e-mail]", selectedanswer: {0: 3, 1: 2, 2: 0, 3: 3, 4: 1} }; angular js code

http（{
url：/ page / PostFileWithData，
header：{
'Content-Type'：'application / json; charset = utf-8'
}，
方法：POST，
dataType：json，
传统：true，
数据：JSON.stringify（postdata）
}）。success（函数（数据）{
console.log（data）;
}）。error（ function（data）{
console.log（'fail'）;
}）;

controller

public JsonResult PostFileWithData（UserModel userdata）
{
UserModel udata = new UserModel
{
Email = userdata .Email
selectedanswer = userdata.selectedanswer
};
返回Json（udata，JsonRequestBehavior.AllowGet）;

}



我的模态


公共类UserModel
{

公共字符串电子邮件{get;组; }
public string selectedanswer {get;组; }



}


现在的问题是我在console.log中收到电子邮件字段确定但是selectanswer是null


喜欢这个

{电子邮件：[e-mail]，selectedanswer：null}
