<asp:HiddenField> 控件 实现键值对保存

前台:

    <asp:HiddenField ID="HfContacts" runat="server" Value="" />

   var item = { name: _name, tel: _tel };
                contacts.push(item);
                $("#HfContacts").val(JSON.stringify(contacts));

后台：

 [DataContract]
    class Contact
    {
        [DataMember]
        public string name { get; set; }
        [DataMember]
        public string tel { get; set; }

    }

   //保存联系方式
                    Dictionary<string, string> wayContact = new Dictionary<string, string>();
                    List<Contact> contacts = BaiKeTool.SerializationHelper.JsonDeserialize<List<Contact>>(HfContacts.Value);
                    foreach (var item in contacts)
                    {
                        wayContact.Add(item.name, item.tel);
                    }
