c#和UDP SOCKET广播
server:
Socket sock = new Socket(AddressFamily.InterNetwork, SocketType.Dgram,ProtocolType.Udp);
IPEndPoint iep1 = new IPEndPoint(IPAddress.Broadcast, 9050);//255.255.255.255
IPEndPoint iep2 = new IPEndPoint(IPAddress.Parse("192.168.1.255"), 9050);
string hostname = Dns.GetHostName();
byte[] data = Encoding.ASCII.GetBytes(hostname);
sock.SetSocketOption(SocketOptionLevel.Socket,SocketOptionName.Broadcast, 1);
sock.SendTo(data, iep1);
sock.SendTo(data, iep2);
sock.Close();
client:
Socket sock = new Socket(AddressFamily.InterNetwork,
SocketType.Dgram, ProtocolType.Udp);
IPEndPoint iep = new IPEndPoint(IPAddress.Any, 9050);
sock.Bind(iep);
EndPoint ep = (EndPoint)iep;
Console.WriteLine("Ready to receive…");
byte[] data = new byte[1024];
int recv = sock.Receivefrom(data, ref ep);
string stringData = Encoding.ASCII.GetString(data, 0, recv);
Console.WriteLine("received: {0} from: {1}",
stringData, ep.ToString());
data = new byte[1024];
recv = sock.Receivefrom(data, ref ep);
stringData = Encoding.ASCII.GetString(data, 0, recv);
Console.WriteLine("received: {0} from: {1}",
stringData, ep.ToString());
sock.Close();

这些天因为工作需要，要将一些html文件转换为chm文件，当然是需要和程序结合在一起。
后来找到NDoc，里头有一段代码是相关的，于是开始分析代码，写完之后，总结：主要是利用微软的hhc.exe来编译html文件，程序需要将具体的数据写入hhp和hhc文件。
主要代码如下：

1.安装ODP（oracle data provider）
2.然后在项目中引用 Oracle.DataAccess程序集
3.接着
using Oracle.DataAccess.Client;
using Oracle.DataAccess.Types;
4.然后编写程序和ado.net方位sqlserver 差别不大了，就是利用下面的对象进行编程，当然，因为oracle和sqlserver有很多地方不一样，所以细节存在很大差异。
