如何在asp.net中将数组传递给webservice

Question

我试图在 ajax 中将数组作为参数传递，但收到错误消息。请告诉我如何将数组传递给网络服务。

错误

网络服务方法

[WebMethod(Description = "Add Session List")]
    [ScriptMethod(UseHttpGet = false)]
    public stringAddSession(string org, string ins, string brn, string startdate, string enddate, string[] classes, string[] subjects, object[] classsubjects)
    {

       return "abc";
    }

ajax 调用

$.ajax({
            type: "POST",
            url: /Services/session/SessionService.asmx/AddSession,
            contentType: "application/json; charset=utf-8",
            data: JSON.stringify({ 'org': OrgID, 'ins': InsID, 'brn': BrnID, 'startdate': StartDate, 'enddate': EndDate, 'classes': Classes, 'subjects': Subjects, 'classsubjects': ClassesWithSubjects };),
            dataType: "json",
            processData: false,
            success: object,
            error: function (err) {
                console.log("AJAX ERROR");
                alert(err.responseText);
            }
        });

你也可以通过使用下面的代码 sn-p 来实现同样的事情。

var classes = new Array();
classes.push('calss1');
classes.push('class2');

var data = new Object();
data.org = OrgID; //How to add object
data.classes = classes; //How to add array

.......
.......
data:  JSON.stringify(data);
.......
.......
