C#正则表达式编程（三）：Match类和Group类用法 收藏 此文于2010-03-09被推荐到CSDN首页
如何被推荐？
前面两篇讲述了正则表达式的基础和一些简单的例子，这篇将稍微深入一点探讨一下正则表达式分组，在.NET中正则表达式分组是用Math类来代表的。
首先先看一段代码：

send :
string path = "E:\\c#\\convey_file\\convey_file\\Form1.cs"; //要传输的文件
TcpClient client = new TcpClient();
client.Connect(IPAddress.Parse("192.168.0.52"),9999);
FileStream file = new FileStream(path,FileMode.Open,FileAccess.Read); // ......

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

最近在忙于 将租赁管理系统mssql数据库转移至firebird数据 以减少成本负担 这个常见问题解决方案留给大家 有更好的或者撇砖块的来着不拒 呵呵
MS-sql在通常 C#代码里 我们提交一个查询字符串 只需如： string sql=" select id 编号,[name] 姓名,sex 性别 from users";
提交即可返回table
但是在 firebird在字段 命名或者 ......
