C# 将数字数组从JS发送到asp.net MVC操作

C# 将数字数组从JS发送到asp.net MVC操作,c#,jquery,asp.net,http-post,C#,Jquery,Asp.net,Http Post,我想将数字数组发送到我的back操作,无论我尝试什么,我都会得到NULL或error。这是我当前的代码 JS $.ajax({ traditional: true, dataType: "json", contentType: 'application/json; charset=utf-8', type: "POST", data: JSON.stringify(groupIds), url: '/

我想将数字数组发送到我的back操作,无论我尝试什么,我都会得到NULL或error。这是我当前的代码

JS

$.ajax({
        traditional: true,
        dataType: "json",
        contentType: 'application/json; charset=utf-8',
        type: "POST",
        data: JSON.stringify(groupIds),
        url: '/Admin/ReadMessages',
        error: function (error) {
            swal.fire({
                title: "Something went wrong. Please try again later.",
                type: "error"
            });
        }
    });
MVC

public ActionResult ReadMessages(List<long> groupIds)
{
     return new HttpStatusCodeResult(HttpStatusCode.OK);
}
public ActionResult ReadMessages(列出组ID)
{
返回新的HttpStatusCodeResult(HttpStatusCode.OK);
}
有什么想法吗?

试试这个

var arr= new Array();
arr.push(1);
arr.push(2); 

$.ajax({  
    type: "POST",
    url: urlToPost,
    data: JSON.stringify(arr),
    contentType: "application/json"
   });
在控制器中:

public ActionResult ReadMessages(IEnumerable<long> groupIds))
{
     return new HttpStatusCodeResult(HttpStatusCode.OK);
}
public ActionResult ReadMessages(IEnumerable groupId))
{
返回新的HttpStatusCodeResult(HttpStatusCode.OK);
}

只是为了给其他人澄清,正如@Amin所说的,我意识到,错误在于发送非数组对象,我使用了map函数,它返回了一些jquery数组,但当我实例化
新数组并发送它时,它工作得非常好

$.ajax({
    traditional: true,
    dataType: "json",
    contentType: 'application/json; charset=utf-8',
    type: "POST",
    data:{groupIds:groupIds},
    url:'@Url.Action("ReadMessages", "Admin")',
    error: function (error) {
        swal.fire({
            title: "Something went wrong. Please try again later.",
            type: "error"
        });
    }
});
控制器:

[HttpPost]
public ActionResult ReadMessages(IEnumerable<long> groupIds))
{
     return new HttpStatusCodeResult(HttpStatusCode.OK);
}
[HttpPost]
公共操作结果读取消息(IEnumerable GroupId))
{
返回新的HttpStatusCodeResult(HttpStatusCode.OK);
}

U帮助我意识到我做错了什么,错误不在帖子中,而是在我的数组中。。。Ty@Serlok我确实考虑过了,所以我决定把数组放在这里。所以我很乐意帮助你;)
