这是我的代码behid webmethod

[WebMethod]
public static string AddCustomer(Customer[] CustomerArr)
{
   return "some result";
}

这是我在控制台中获得的异常

你应该传递同名的对象数组

 $.ajax({
                type: 'POST',
                url: 'Default2.aspx/AddCustomer',
                data: {CustomerArr:param },
                // same name
                contentType: 'application/json; charset=utf-8',
                dataType: 'json',
                success: function(result) {
                alert(result.d);
                }
            });

将Json对象传递给webmethod，给出内部服务器错误500
