客户端用户登陆后，在主界面中可以看到本单位的所有教室，我们来看一下是如何获取的：
客户端代码：
//根据用户获取功能教室列表
private void GetRooms(Users user)
{
//把当前用户信息发送个服务器端，并获取到本用户相关的教室列表
RoomList roomList = newTcpConnection.SendReceiveObject<RoomList>("GetRooms", "RoomList", 5000, user);
IList<ClassRoom> classRomms= roomList.ClassRooms;
listBox1.DataSource = classRomms;
listBox1.DisplayMember = "RoomName";
listBox1.ValueMember = "ID";
}
RoomList类 （可由protobuf.net 序列化）
//根据单位名称获取功能室列表 [ProtoContract] public class RoomList
{
[ProtoMember(1)] public IList<ClassRoom> ClassRooms; public RoomList() { } public RoomList(IList<ClassRoom> rooms)
{ this.ClassRooms = rooms;
}
}
服务器端的处理方法：
在构造函数中声明：
//根据用户的单位，获取所有功能教室 列表
NetworkComms.AppendGlobalIncomingPacketHandler<Users>("GetRooms", HandleGetRooms);处理方法：
private void HandleGetRooms(PacketHeader header, Connection connection, Users theUser)
{
IList<ClassRoom> theRooms = DoClassRoom.GetClassRoomByUserDep(theUser.Department);
RoomList roomList = new RoomList(theRooms); //把获取到的数据发回去
connection.SendObject("RoomList", roomList);
}
DoClassRoom.GetClassRoomByUserDep方法
//根据用户单位获取单位的功能教室列表
public static IList<ClassRoom> GetClassRoomByUserDep(string depName)
{
IDataReader reader = DBClassRoom.GetClassRoomByDepName(depName); return LoadListFromReader(reader);
}
LoadListFromReader方法
DBClassRoom.GetClassRoomByDepName方法
//根据单位名称获取功能教师列表
public static IDataReader GetClassRoomByDepName(string department)
{
SqlParameterHelper sph = new SqlParameterHelper(GetWriteConnectionString(), "ClassRoom_SelectClassRoomByDepName", 1);
sph.DefineSqlParameter("@Department", SqlDbType.NVarChar, 200, ParameterDirection.Input, department); return sph.ExecuteReader();
}
相关存储过程：
CREATE PROCEDURE [dbo].ClassRoom_SelectClassRoomByDepName @Department nvarchar(200) AS SELECT [Id], [RoomName], [DepID], [Department] FROM [dbo].[ClassRoom] where Department=@Department
