IPEndPoint iep1 = new IPEndPoint(IPAddress.Broadcast, 9050);//255.255.255.255
IPEndPoint iep2 = new IPEndPoint(IPAddress.Parse("192.168.1.255"), 9050);

byte[] data = Encoding.ASCII.GetBytes(hostname);

一直没有找到一种好的方法来引用有返回值的存储过程的方法，使我在添加数据中走了不少的弯路，最近，在查阅了大量的资料之后，终于在微软的一个实例中找到了一种良好的方法。
首先编写好一有返回值的存储过程
create procedure proc_name
@para1 nchar(20), --输入参数
@ ......
非常简单,在C#中只需要在类的方法的上方敲三下"/"就自动帮你添加相关的代码,你只要按着填写就可以了,而Java则是输入"/**",它也会自动形成相关代码,具体代码如下:
C#
/// <summary>
/// 在此填写总体描述
///</summary>
/// <param name="name">这里填写参数name的描述</param>
public string ......
