$.ajax({
url: <Url of the action>,
type: "POST",
data: JSON.stringify([1,2,3]),
dataType: "json",
contentType: 'application/json; charset=utf-8'
});
and in the action.
并在行动中。
public ActionResult ReceiveIntArray(int[] ints)
{
...
}
mvc should parse the json automatically.
mvc 应该自动解析 json。

Try solution from this question:
试试这个问题的解决方案：
Set the
traditionalproperty to true before making the get call. i.e.:jQuery.ajaxSettings.traditional = true $.get('/controller/MyAction', { vals: arrayOfValues }, function (data) { ... }
traditional在进行 get 调用之前将该属性设置为 true。IE：jQuery.ajaxSettings.traditional = true $.get('/controller/MyAction', { vals: arrayOfValues }, function (data) { ... }

The simplest way would be to send a delimited (commas, possibly) string list of the ints as an argument on a GET request, then use Sting.Split()to parse them on your C# MVC receiver.
最简单的方法是将整数的分隔（可能是逗号）字符串列表作为 GET 请求的参数发送，然后用于Sting.Split()在 C# MVC 接收器上解析它们。
So, for example
$.get("/path-to/receiver/", { myArray: myArray.toString() } );
所以，例如
$.get("/path-to/receiver/", { myArray: myArray.toString() } );
Then, on the server, use
然后，在服务器上，使用
string[] stringArray = Request.QueryString["myArray"].ToString().Split(',')
string[] stringArray = Request.QueryString["myArray"].ToString().Split(',')
to extract the values to a string array, then Int32.TryParseto finally get an array of ints.
将值提取到一个字符串数组，然后Int32.TryParse最终得到一个整数数组。

The way I'm doing it is with a simple input:hiddenelement
我这样做的方式是使用一个简单的input:hidden元素
<input type="hidden" name="elements" value='@String.Join(",", ViewBag.MyArray)' />
And in the JavaScript code I'm passing it as a string:
在 JavaScript 代码中，我将它作为字符串传递：
$.ajax({
type: "POST",
url: '/Controller/Method',
data:
{
recipients: $("input[name=elements]").val()
},
traditional: true,
success: updateSelected
});
And finally I just Splitthe elements like this:
最后我只是这样Split的元素：
[AcceptVerbs(HttpVerbs.Post)]
public ActionResult Method(string elements)
{
IList<long> selected = elements.Split<long>(',');
...
}

$.ajax({
type: "Post",
datatype: "Json",
url: <Url of the action>,
data: JSON.stringify(Array),
contentType: 'application/json; charset=utf-8',
});
