1一、从控制台读取东西代码片断:
2using System;
3
4class TestReadConsole
5{
6 public static void Main()
7 {
8 Console.Write(Enter your name:);
9 string strName = Console.ReadLine();
10 Console.WriteLine( Hi + strName);
11 }
12}
13二、读文件代码片断:
14using System;
15using System.IO;
16
17public class TestReadFile
18{
19 public static void Main(String[] args)
20 {
21 // Read text file C:\temp\test.txt
22 FileStream fs = new FileStream(@c:\temp\test.txt , FileMode.Open, FileAccess.Read);
23 StreamReader sr = new StreamReader(fs);
24
25 String line=sr.ReadLine();

27 {
28 Console.WriteLine(line);
29 line=sr.ReadLine();
30 }
31
32 sr.Close();
33 fs.Close();
34 }
35}
36三、写文件代码:
37using System;
38using System.IO;
39
40public class TestWriteFile
41{
42 public static void Main(String[] args)
43 {
44 // Create a text file C:\temp\test.txt
45 FileStream fs = new FileStream(@c:\temp\test.txt , FileMode.OpenOrCreate, FileAccess.Write);
46 StreamWriter sw = new StreamWriter(fs);
47 // Write to the file using StreamWriter class
48 sw.BaseStream.Seek(0, SeekOrigin.End);
49 sw.WriteLine( First Line );
50 sw.WriteLine( Second Line);
51 sw.Flush();
52 }

79
80class TestTimer
81{
82 public static void Main()
83 {
84 Timer timer = new Timer();

95
96 public static void DisplayTimeEvent( object source, ElapsedEventArgs e )
97 {
98 Console.Write(\r{0}, DateTime.Now);
99 }
100}
101七、调用外部程序:
102class Test

104 static void Main(string[] args)
105 {
106 System.Diagnostics.Process.Start(notepad.exe);
107 }
108}
109
110ADO.NET方面的:

189
190 String strSql = SELECT FirstName, LastName FROM employees;
191
192 SqlDataAdapter adapter = new SqlDataAdapter();
193
194 adapter.SelectCommand = new SqlCommand(strSql,conn);
195
196 // Build the DataSet
197 DataSet ds = new DataSet();
198
199 adapter.Fill(ds, employees);
200
201 // Get a FileStream object
202 FileStream fs = new FileStream(strFileName,FileMode.OpenOrCreate,FileAccess.Write);
203
204 // Apply the WriteXml method to write an XML document
205 ds.WriteXml(fs);
206
207 fs.Close();
208
209 }
210}
211十一、用ADO添加数据到数据库中:

285 cmd.Fill( ds, employee );
286 DataTable dt = ds.Tables[0];
287
288 Console.WriteLine(Field Name DataType Unique AutoIncrement AllowNull);
289 Console.WriteLine(==================================================================);
290 foreach( DataColumn dc in dt.Columns )
291 {
292 Console.WriteLine(dc.ColumnName+ , +dc.DataType + ,+dc.Unique + ,+dc.AutoIncrement+ ,+dc.AllowDBNull );
293 }
294 conn.Close();

120 string strDSN = Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\\test.mdb;
121 string strSQL = SELECT * FROM employees ;
122
123 OleDbConnection conn = new OleDbConnection(strDSN);
124 OleDbCommand cmd = new OleDbCommand( strSQL, conn );
125 OleDbDataReader reader = null;
126 try
127 {
128 conn.Open();
129 reader = cmd.ExecuteReader();
130 while (reader.Read() )
131 {
132 Console.WriteLine(First Name:{0}, Last Name:{1}, reader[FirstName], reader[LastName]);
133 }
134 }
135 catch (Exception e)
136 {
137 Console.WriteLine(e.Message);
138 }
139 finally
140 {
141 conn.Close();
142 }
143 }
144}
145九、连接SQL Server数据库:
146using System;
147using System.Data.SqlClient;
148
149public class TestADO
150{
151 public static void Main()
152 {
153 SqlConnection conn = new SqlConnection(Data Source=localhost; Integrated Security=SSPI; Initial Catalog=pubs);
154 SqlCommand cmd = new SqlCommand(SELECT * FROM employees, conn);
155 try
156 {
157 conn.Open();
158
159 SqlDataReader reader = cmd.ExecuteReader();
160 while (reader.Read())
161 {
162 Console.WriteLine(First Name: {0}, Last Name: {1}, reader.GetString(0), reader.GetString(1));
163 }
164
165 reader.Close();
166 conn.Close();
167 }
168 catch(Exception e)
169 {
170 Console.WriteLine(Exception Occured -->> {0},e);
171 }
172 }
173}
174十、从SQL内读数据到XML:
175using System;
176using System.Data;
177using System.Xml;
178using System.Data.SqlClient;
179using System.IO;
180
181public class TestWriteXML
182{
183 public static void Main()
184 {
185
186 String strFileName=c:/temp/output.xml;
187
188 SqlConnection conn = new SqlConnection(server=localhost;uid=sa;pwd=;database=db);
189
190 String strSql = SELECT FirstName, LastName FROM employees;
191
192 SqlDataAdapter adapter = new SqlDataAdapter();
193
194 adapter.SelectCommand = new SqlCommand(strSql,conn);
195
196 // Build the DataSet
197 DataSet ds = new DataSet();
198
199 adapter.Fill(ds, employees);
200
201 // Get a FileStream object
202 FileStream fs = new FileStream(strFileName,FileMode.OpenOrCreate,FileAccess.Write);
203
204 // Apply the WriteXml method to write an XML document
205 ds.WriteXml(fs);
206
207 fs.Close();
208
209 }
210}
211十一、用ADO添加数据到数据库中:
212using System;
213using System.Data;
214using System.Data.OleDb;
215
216class TestADO
217{
218 static void Main(string[] args)
219 {
220 string strDSN = Provider=Microsoft.Jet.OLEDB.4.0;DataSource=c:\test.mdb;
221 string strSQL = INSERT INTO Employee(FirstName, LastName) VALUES('FirstName', 'LastName') ;
222
223 // create Objects of ADOConnection and ADOCommand
224 OleDbConnection conn = new OleDbConnection(strDSN);
225 OleDbCommand cmd = new OleDbCommand( strSQL, conn );
226 try
227 {
228 conn.Open();
229 cmd.ExecuteNonQuery();
230 }
231 catch (Exception e)
232 {
233 Console.WriteLine(Oooops. I did it again:\n{0}, e.Message);
234 }
235 finally
236 {
237 conn.Close();
238 }
239 }
240}
241十二、使用OLEConn连接数据库:

243using System.Data;
244using System.Data.OleDb;
245
246class TestADO
247{
248 static void Main(string[] args)
249 {
250 string strDSN = Provider=Microsoft.Jet.OLEDB.4.0;DataSource=c:\test.mdb;
251 string strSQL = SELECT * FROM employee ;
252
253 OleDbConnection conn = new OleDbConnection(strDSN);
254 OleDbDataAdapter cmd = new OleDbDataAdapter( strSQL, conn );
255
256 conn.Open();
257 DataSet ds = new DataSet();
258 cmd.Fill( ds, employee );
259 DataTable dt = ds.Tables[0];
260
261 foreach( DataRow dr in dt.Rows )
262 {
263 Console.WriteLine(First name: + dr[FirstName].ToString() + Last name: + dr[LastName].ToString());
264 }
265 conn.Close();
266 }
267}
268十三、读取表的属性:
269using System;
270using System.Data;
271using System.Data.OleDb;
272
273class TestADO
274{
275 static void Main(string[] args)
276 {
277 string strDSN = Provider=Microsoft.Jet.OLEDB.4.0;DataSource=c:\test.mdb;
278 string strSQL = SELECT * FROM employee ;
279
280 OleDbConnection conn = new OleDbConnection(strDSN);
281 OleDbDataAdapter cmd = new OleDbDataAdapter( strSQL, conn );
282
283 conn.Open();
284 DataSet ds = new DataSet();
285 cmd.Fill( ds, employee );
286 DataTable dt = ds.Tables[0];
287
288 Console.WriteLine(Field Name DataType Unique AutoIncrement AllowNull);
289 Console.WriteLine(==================================================================);
290 foreach( DataColumn dc in dt.Columns )
291 {
292 Console.WriteLine(dc.ColumnName+ , +dc.DataType + ,+dc.Unique + ,+dc.AutoIncrement+ ,+dc.AllowDBNull );
293 }
294 conn.Close();
295 }
296}
297
298ASP.NET方面的

300<%@ Page Language=C# %>
301<script runat=server>
302
303 void Button1_Click(Object sender, EventArgs e)
304 {
305 Label1.Text=TextBox1.Text;
306 }
307
308</script>
309<html>
310<head>
311</head>
312<body>
313 <form runat=server>
314 <p>
315 <br />
316 Enter your name: <asp:TextBox id=TextBox1 runat=server></asp:TextBox>
317 </p>
318 <p>
319 <b><asp:Label id=Label1 runat=server Width=247px></asp:Label></b>
320 </p>
321 <p>
322 <asp:Button id=Button1 onclick=Button1_Click runat=server Text=Submit></asp:Button>
323 </p>
324 </form>
325</body>
326</html>
327

345 {
346 InitializeComponent();
347 }
348
349 protected override void Dispose( bool disposing )
350 {
351 if( disposing )
352 {
353 if (components != null)
354 {

406 [STAThread]
407 static void Main()
408 {
409 Application.Run(new SimpleForm());
410 }
411}
412十六、运行时显示自己定义的图标:
413//load icon and set to form
414System.Drawing.Icon ico = new System.Drawing.Icon(@c:\temp\app.ico);
415this.Icon = ico;
416十七、添加组件到ListBox中:
417private void Form1_Load(object sender, System.EventArgs e)
418{
419 string str = First item;
420 int i = 23;
421 float flt = 34.98f;
422 listBox1.Items.Add(str);
423 listBox1.Items.Add(i.ToString());

440 {
441 Console.WriteLine (IP Address {0}: {1} , i, IpAddr.ToString ());
442 }
443 }
444}
445十九、取得机器名称:

459using System.Web.Mail;
460
461public class TestSendMail
462{
463 public static void Main()
464 {

468 MailMessage message = new MailMessage();
469 message.From = from@domain.com;
470 message.To = pengyun@cobainsoft.com;
471 message.Cc = ;
472 message.Bcc = ;
473 message.Subject = Subject;
474 message.Body = Content of message;
475
476 //if you want attach file with this mail, add the line below
477 message.Attachments.Add(new MailAttachment(c:\\attach.txt, MailEncoding.Base64));
478
479 // Send the message
480 SmtpMail.Send(message);
481 System.Console.WriteLine(Message has been sent);
482 }

494
495class ResolveIP
496{
497 public static void Main()
498 {
499 IPHostEntry ipEntry = Dns.Resolve(172.29.9.9);
