入门——————————————————————————–
概述与概念
一个C#程序开始于一个单线程，这个单线程是被CLR和操作系统（也称为“主线程”）自动创建。
创建和开始使用多线程
public Window1()
{
//主线程
//Code……
//使用匿名方法来启动子线程
Thread t = new Thread(delegate() {Code……});
t.Start();
}
子进程创建实例
//1.创建子线程
public Window1()
{
//创建子进程
Thread threadA = new Thread(new ThreadStart(WorkMethod));
threadA.Start();
}
//子进程启动程序
void WorkMethod()
{
this.textBox1.Dispatcher.Invoke(DispatcherPriority.Normal, (ThreadStart)delegate
{
textBox1.AppendText(Environment.NewLine);
this.textBox1.AppendText(“子线程执行完成!”);
});
}
//2.使用匿名委托来启动子线程
public Window1()
{
Thread t = new Thread(delegate() {
this.textBox1.Dispatcher.Invoke(DispatcherPriority.Normal, (ThreadStart)delegate
{
textBox1.AppendText(Environment.NewLine);
this.textBox1.AppendText(“子线程执行完成!”);
});
});
t.Start();
}
//3.使用匿名委托来启动子线程
public Window1()
{
InitializeComponent();
textBox1.AppendText(“主线程执行完成”);
new Thread(() =>
{
this.Dispatcher.Invoke(new Action(() =>
{
textBox1.AppendText(Environment.NewLine);
textBox1.AppendText(“子线程执行完成”);
}));
}).Start();
}
线程同步基础——————————————————————————–
同步要领
锁和线程安全
//将当前线程阻塞指定的时间
Thread.Sleep(TimeSpan.FromSeconds(30));
Interrupt 和 Abort
线程状态
等待句柄
同步环境
使用多线程——————————————————————————–
单元模式和Windows Forms
BackgroundWorker类
ReaderWriterLock类
线程池
异步委托
计时器
public Window1()
{
//计时器 SetTimeInterval
System.Windows.Threading.DispatcherTimer t = new System.Windows.Threading.DispatcherTimer();
t.Interval = new TimeSpan(0, 0, 0, 0, 100);
t.Tick += new EventHandler(timer_Interval);
t.Start();
}
public Window1()
{
//计时器 SetTimeOut
new System.Threading.Timer(new TimerCallback(timer_Callback), this, 5000, 0);
}
局部储存
高级话题——————————————————————————–
非阻止同步
Wait和Pulse
Suspend和Resume
终止线程
同步线程实例
public Window1()
{
InitializeComponent();
this.WindowStartupLocation = WindowStartupLocation.CenterOwner;
this.textBox1.Dispatcher.Invoke(DispatcherPriority.Normal, (ThreadStart)delegate
{
textBox1.AppendText(Environment.NewLine);
this.textBox1.AppendText(“同步线程执行完成!”);
});
}
异步线程实例
public Window1()
{
textBox1.Dispatcher.BeginInvoke(DispatcherPriority.Normal, (Action)(() =>
{
textBox1.AppendText(Environment.NewLine);
textBox1.AppendText(“异步线程执行完成”);
}));
}
线程呈现控件实例-可传参数
public Window1()
{
InitializeComponent();
System.Windows.Threading.DispatcherTimer t = new System.Windows.Threading.DispatcherTimer();
t.Interval = new TimeSpan(0, 0, 0, 0, 1000);
t.Tick += new EventHandler(Dispatcher_Timer);
t.Start();
}
private delegate void DispatcherDelegate(string msg);
private void OutPut(string msg)
{
textBox1.Dispatcher.Invoke(new DispatcherDelegate(DelegateMethod), msg);
}
private void DelegateMethod(string msg)
{
textBox1.AppendText(msg);
textBox1.AppendText(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”));
textBox1.AppendText(Environment.NewLine);
}
void Dispatcher_Timer(object sender, EventArgs e)
{
OutPut(“控件呈现：”);
}
线程呈现控件实例-使用匿名委托
public Window1()
{
InitializeComponent();
this.WindowStartupLocation = WindowStartupLocation.CenterOwner;
System.Windows.Threading.DispatcherTimer t = new System.Windows.Threading.DispatcherTimer();
t.Interval = new TimeSpan(0, 0, 0, 0, 1000);
t.Tick += new EventHandler(Dispatcher_Timer);
t.Start();
}
void Dispatcher_Timer(object sender, EventArgs e)
{
textBox1.Dispatcher.BeginInvoke(DispatcherPriority.Normal, (Action)(() =>
{
textBox1.AppendText(“控件呈现：”);
textBox1.AppendText(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”));
textBox1.AppendText(Environment.NewLine);
}));
}
线程呈现控件实例-匿名方法并返回参数
public Window1()
{
InitializeComponent();
System.Windows.Threading.DispatcherTimer t = new System.Windows.Threading.DispatcherTimer();
t.Interval = new TimeSpan(0, 0, 0, 0, 1000);
t.Tick += new EventHandler(Dispatcher_Timer);
t.Start();
}
void Dispatcher_Timer(object sender, EventArgs e)
{
string strmsg = (string)textBox1.Dispatcher.Invoke(new Func<string>(() =>
{
textBox1.AppendText(“控件呈现：”);
textBox1.AppendText(DateTime.Now.ToString(“yyyy-MM-dd hh:mm:ss”));
textBox1.AppendText(Environment.NewLine);
return textBox1.Text;
}));
}
