parametersstatic void Threadmethodparameter (object Parameter){for (int j = 0; J {Console.WriteLine ("B" +parameter);}}}}Open two threads respectively in the agent.The first thread Threada without parameters, and the thread runs to execute the Threadmethod () method.The second thread threadb with an object parameter and executes the Threadmethodparameter (object Parameter) method with the Parameterizedthreadstart delegate. This thread is calling start () When you pass in the required parameters
Third, thread timer (System.Threading.Timer)
Thread timers also do not rely on forms, a simple, lightweight timer that uses callback methods instead of events and is supported by thread pool threads. Thread timers are useful in scenarios where messages are not sent on a thread.
The code example is given here only for the use of the console thread timer, followed by several other code examples:
Using System;
Using System.Collections.Generic;
Using System.Runtime.InteropServices;

Cmd.commandtext = "SELECT * from Test";
Sqlitedataadapter da = new Sqlitedataadapter ();
Da. SelectCommand = cmd;
DataSet ds = new DataSet ();
Da. Fill (DS);

Select * from Test Limit 10;
The above statement represents fetching data from the account table, skipping 10 rows, and taking 10 rows

This article illustrates how C # implements exporting list data to XML files. Share to everyone for your reference, specific as follows:
C # Exports list data to an XML file, where the main uses are:
XmlSerializer Class (System.Xml.Serialization)
Serializes an object into an XML document and deserializes an object from an XML document. XmlSerializer allows you to control how objects are encoded into XML.
The example in this article describes how the C # Simple implementation shows the day of the week in Chinese format. Share to everyone for your reference, specific as follows:

(); } void Run () {Console.WriteLine (THRD).
Name + "is waiting for a license (card) ...");
If you do not add a parameter, it can cause infinite wait. if (MySemaphore.sem.WaitOne (1000)) {Console.WriteLine (THRD).
Name + "Apply to license (certificate) ...");
Thread.Sleep (500);
Although the license is added below, other threads may not have permission to exit the timeout. Console.WriteLine (THRD.
Name + "Add a license (card) ...");
MySemaphore.

Hashtable Hashtable = new Hashtable ();

This shows that when you add data hashtable fast. Dictionary fast when you call data frequently.
