hello, On my site in ASP.Net MVC, I try to send the contents of an array in a function using a POST but nothing happens and I don't understand why. My class :

public class AdresseIP
{
public int? Idclient { get; set; }
public int? ip1 { get; set; }
public int? ip2 { get; set; }
public int? ip3 { get; set; }
public int? ip4 { get; set; }
public int? idplan { get; set; }
}

My function (empty for the moment):

[HttpPost]
public ActionResult MAJIP(IEnumerable lst)

{


    return View(1);
}

The method I use to send the array from my page:

function Valider(tableID) {
console.log("test " + tableID);
var IPs = new Array();
$("#" + tableID + " TBODY TR").each(function () {
var row = $(this);
var IP = {};
IP.Idclient = row.find("TD").eq(0).text();
IP.idplan = row.find("TD").eq(1).text();
IP.ip1 = row.find("TD").eq(2).text();
IP.ip2 = row.find("TD").eq(3).text();
IP.ip3 = row.find("TD").eq(4).text();
IP.ip4 = row.find("TD").eq(5).text();
IPs.push(IP);

});

console.log(JSON.parse(JSON.stringify(IPs)));
IPs2 = JSON.parse(JSON.stringify(IPs));
console.log(IPs2);

    $.ajax({
        type: "POST",
        url: "/IP/MAJIP/",
        data: IPs2,
        contentType: "application/json; charset=utf-8",
        dataType: "json",
        success: function (r) {
            alert(r);
            if (r == 1) {
                console.log('test1 ' + r)
            } else {
                console.log('test2 ' + r);
            }

        }
    });

}

The console.log(IPs); displays the contents of the array correctly. There may be better methods, but I don't know of any. When I validate, my function receives a Null. Yet all my console.log(IPs); return the expected value. So here I don't know. Any idea please?
