How to pass list from ajax to controller

I have a controller like so..

public ActionResult Report(List<string> invoiceIds)

and I have an ajax call like so...

function generateAccountsPayableReports() {
    var ms = $("#msInvoicesAPV").data("kendoMultiSelect");
    var invoices = ms.dataItems();
    var invoiceIds = [];

    invoices.forEach(function (invoice) {
        invoiceIds.push(invoice.Id);
    });

    //invoiceIds = JSON.stringify(invoiceIds); 
    console.log("InvoiceIds: ", invoiceIds);

    $.ajax({
        type: "GET",
        url: "/APV/Report",
        contentType: "application/json; charset=utf-8",
        data: JSON.stringify(invoiceIds),
        success: function (result) {
            if (result) {
                console.log("result: ", result);
            }
        },
        failure: function (result) {
            console.error("result: ", result);
        },
        error: function (result) {
            console.error("result: ", result);
        }
    });
}

I have tried everything I could think of:

when I tried this, it passed in the controller but on a single element only..

{'invoiceIds': JSON.stringify(invoiceIds)}

It was passed on one element only

nothing seems to work... what am I doing wrong?

by the way the array in javascript are guid

how do I pass it properly?

You can try like this way

var ajaxData = { invoiceIds: invoiceIds };

than passing the data like this way through ajax

data: ajaxData

Instead of List<string> declare an array of string in the method controller so it should look like this Report(string[] invoiceIds) and to the ajax call just bind array to data: like this data: invoiceIds

you use type as "GET" and not "POST", use "POST" and don't change anything, normally it will work like that It seems it receive ONE string in your LIST
