利用飞信的协议可以在线收发消息，或是向手机发送消息。由此，可以自己来完成一个IM工具。
本文即是对飞信SDK的使用方法，及如何开发作一个说明。
FetionSDK下载：http://www.fzzsh.cn/software/FetionSDK.rar
贴一下核心代码:
private FetionSDK sdk = new FetionSDK();//实例化飞信sdk
sdk.SDK_ReceiveMessage += new FetionSDK.SDK_ReceiveMessageEventHandler(sdk_SDK_ReceiveMessage);//消息接收事件
sdk.SDK_UserSatusChange += new FetionSDK.SDK_UserSatusChangedEventHandler(Sdk_SDK_UserSatusChange);//用户状态事件
sdk.SDK_Error += new FetionSDK.SDK_ErrorEventHandler(Sdk_SDK_Error);//sdk错误事件
/// <summary>
/// 登陆飞信
/// </summary>
private bool FetionLogin(string userName,string pwd)
{
sdk.AccountManager.FillUserIdAndPassword(userName, pwd, false);//第三个参数为是否自动登陆
bool isOk=sdk.AccountManager.Login();//登陆
return isOk;
}
/// <summary>
/// 发送消息
/// </summary>
private bool SendFetionMsg(string userName, string msg)
{
bool isOk = false;
try
{
int state = sdk.ContactControl.SendIM.SendIM(userName, msg);
}
catch { isOk = false; }
return isOk;
}
/// <summary>
/// 发送手机消息
/// </summary>
private bool SendFetionMobileMsg(string userName, string msg)
{
bool isOk = false;
try
{
int state = sdk.ContactControl.SendSMS.SendSMS(userName, msg);
}
catch { isOk = false; }
return isOk;
}
/// <summary>
/// 加载好友列表
/// </summary>
/// <param name="psSdk">飞信sdk对象</param>
/// <returns>返回飞信好友信息集合</returns>
private List<FetionFriend> GetFetionFriendList(FetionSDK psSdk)
{
List<FetionFriend> fetionFriends = new List<FetionFriend>();
try
{
List<Imps.Client.Core.Contact> list = psSdk.ContactControl.getAllContactList();
for (int i = 0; i < list.Count; i++)
{
try
{
FetionFriend fetionFriend = new FetionFriend();//自定义飞信用户实体信息类
fetionFriend.UserId = int.Parse(list[i].Uri.Id);
fetionFriend.Nickname = list[i].DisplayName;
fetionFriend.Mobile = list[i].PersonalInfo.MobileNo;
fetionFriends.Add(fetionFriend);
}
catch { }
}
}
catch { fetionFriends = new List<FetionFriend>(); }
return fetionFriends;
}
/// <summary>
/// 飞信sdk出现错误
/// </summary>
private void Sdk_SDK_Error(object sender, NullStudio.Fetion_SDK.Event.SDK_ErrorEventArgs fe)
{
this.txtBox.Text += "错误："+fe.Message.Message+"/r/n";
}
/// <summary>

private void Sdk_SDK_UserSatusChange(object sender, Imps.Client.Core.UserSatusChangedEventArgs e)
{
switch (e.NewStatus.ToString())
{
case "Disconnected"://断开了网络
FetionLogin(userName, userPwd);//重新登陆
break;
case "Initialized"://已初始化
break;
case "Loginning"://登陆中
break;
case "Logon"://已登陆
sdk.AccountManager.CurrentUser.Presence.AsyncChangeMainPresence(Imps.Common.MainPresence.Online, Imps.Common.MainPresence.Online.ToString());//设置PC在线
break;
case "Logoff"://离开网络
break;
case "Logouting"://注销中
break;

break;

}

}

{
this.txtBox.Text += "" + string.Format(fe.Message, fe.Contact.PersonalInfo.Nickname +"("+ fe.Contact.Uri.Sid.ToString()+")") + "/r/n";
}
有几点需要注意的就是:
1、登陆后显示短信在线状态？
需要用sdk.AccountManager.CurrentUser.Presence.AsyncChangeMainPresence(Imps.Common.MainPresence.Online, Imps.Common.MainPresence.Online.ToString());激活一次，显示PC在线，更改用户状态。
2、为什么会经常掉线？
解决办法：间隔一段时间更改一次用户状态，让服务器知道我还在线呢。
