C#的TCP通信
TCP是连接模型，如下：
服务器连接 服务器断开
↓ ↑
服务器接收→服务器处理→服务器发送
↑ ↓
客户端发送←客户端处理←客户端接收
↑ ↓
客户端连接 客户端断开
服务器代码如下：
//
ServerListen
TcpListener tcplistener
=
new
TcpListener(
int
.Parse(txtPort.Text));
tcplistener.Start();
byte
[] btServerReceive
=
new
byte
[
256
];
string
strServerReceive
=
string
.Empty;
//
Loop for Listen
while
(
true
)
{
TcpClient tcp
=
tcplistener.AcceptTcpClient();
NetworkStream ns
=
tcp.GetStream();
int
intReceiveLength
=
ns.Read(btServerReceive,
0
,btServerReceive.Length);
strServerReceive
=
UnicodeEncoding.Unicode.GetString(btServerReceive,
0
,intReceiveLength);
txtServerResult.AppendText(
"
ServerReceive:
"
+
strServerReceive
+
"
"
);
ns.Write(btServerReceive,
0
,btServerReceive.Length);
txtServerResult.AppendText(
"
ServerSend:
"

通过xsl转换大xml文件
这几天在做这个，网上的几个方法我都试过了，汇总如下
方法一：
XPathDocument myXPathDoc = new XPathDocument(tbXMLFile.Text);
XslCompiledTransform myXslTrans = new XslCompiledTransform();
myXslTrans.Load(tbXSLFile.Text);
XmlTextWriter myWriter = new XmlTextWrit ......

///<summary>
/// DbOper类的构造函数

private DbOper()

}
......
//命名空间 using Microsoft.Win32;
private void checkBox2_CheckedChanged(object sender, System.EventArgs e)
{
if (checkBox2.Checked) //设置开机自启动
{
//MessageBox.Show ("设置开机自启动需要修改注册表","提示");
string path = Application.ExecutablePath;
RegistryKey rk = Registry.LocalMac ......
