Silverlight+WCF实现聊天功能

分类：Silverlight作者：编程之家

这是来公司做的第二个项目实例。最近在学习WCF方面的知识，看了一些资料，于是做了这个可以实现聊天功能的项目实例。

新建WCF服务和Silverlight项目就不说了主要来看代码：

WCF服务契约与数据契约：

 <span style="color:#FF0000;"> [ServiceContract(CallbackContract = typeof(IMessageCallBack))]</span>
public interface IMessageManage
    {

        [OperationContract]

        bool SendMessage(MessageInfo msg);

        [OperationContract]

        bool RequestMessage(UserInfo user);

        [OperationContract]
       
        List<UserInfo> GetUserInfo();

        [OperationContract]
        
        bool createuser(UserInfo user);

    }
 public interface IMessageCallBack
    {
<span style="color:#FF0000;">
        [OperationContract(IsOneWay = true)]

        void GetMessage(MessageInfo message);</span>

    }
<pre name="code" class="csharp"><span style="color:#FF0000;">[DataContract]</span>
 public class MessageInfo { [DataMember] public UserInfo FromUser { get; set; } [DataMember] public UserInfo ToUser { get; set; } [DataMember] public string Content { get; set; } [DataMember] public DateTime SendTime { get; set; } }[DataContract] public class UserInfo { [DataMember] public int Id { get; set; } [DataMember] public string Name { get; set; } } 

 WCF的实现：

using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
<span style="background-color: rgb(255,0);">using WcfModel;</span>


namespace WcfService

    public class MessageService : IMessageManage
    {


        private static Dictionary<int,IMessageCallBack> DicCallChannel = new Dictionary<int,IMessageCallBack>();

        public static List<UserInfo> getuserTemp = new List<UserInfo>();

        private int UserId = 0;

        public bool createuser(UserInfo user)
        {
            if (getuserTemp == null)
                getuserTemp = new List<UserInfo>();
            
            bool r = false;
            foreach (UserInfo list in getuserTemp)
            {
                if (list.Id.Equals(user.Id))
                {
                    r = true;
                }
            }
            if (r)
            {
                return false;
            }
            getuserTemp.Add(user);
            return true;

        }

        public bool SendMessage(MessageInfo msg)
        {



            if (DicCallChannel.Keys.Contains(msg.ToUser.Id))
            {

                DicCallChannel[msg.ToUser.Id].GetMessage(msg);

                return true;

            }

            return false;

        }

        public bool RequestMessage(UserInfo user)
        {



            IMessageCallBack channel = OperationContext.Current.GetCallbackChannel<IMessageCallBack>();

            if (!DicCallChannel.Keys.Contains(user.Id))
            {



                DicCallChannel.Add(user.Id,channel);




                UserId = user.Id;

                OperationContext.Current.Channel.Closing += Channel_Closing;

            }

            return true;

        }

        void Channel_Closing(object sender,EventArgs e)
        {

            if (DicCallChannel.Keys.Contains(UserId))
            {

                DicCallChannel.Remove(UserId);

            }

        }
   
        public List<UserInfo> GetUserInfo()
        {
            
            return getuserTemp;


        }
