无参数线程的创建
- public delegate void ThreadStart()
Thread thread = new Thread(new ThreadStart(getpic));
thread.Start();
private void showmessage()
{
Console.WriteLine("hello world");
}
带一个参数的线程
使用ParameterizedThreadStart,调用 System.Threading.Thread.Start(System.Object) 重载方法时将包含数据的对象传递给线程。
注意传递的参数只能是object类型,不过可以进行强制类型转换。
Thread thread = new Thread(new ParameterizedThreadStart(showmessage));
string o = "hello";
thread.Start((object)o);
private static void showmessage(object message)
{
string temp = (string)message;
Console.WriteLine(message);
}
带两个及以上参数的线程
这时候可以将线程执行的方法和参数都封装到一个类里边,通过实例化该类,方法就可以调用属性来尽享传递参数。
例如如下程序,想传入两个string变量,然后打印输出。
public class ThreadTest
{
private string str1;
private string str2;
public ThreadTest(string a, string b)
{
str1 = a;
str2 = b;
}
public void ThreadProc()
{
Console.WriteLine(str1 + str2);
}
}
public class Example {
public static void Main()
{
ThreadTest tt = new ThreadTest("hello ", "world");
Thread thread = new Thread(new ThreadStart(tt.ThreadProc));
thread.Start();
}
}
匿名方法和Lambda表达式
Thread thread1 = new Thread(delegate () {
Console.WriteLine("匿名委托");
});
Thread thread2 = new Thread(()=> {
Console.WriteLine("Lambda表达式");
});
thread1.Start();
thread2.Start();
Console.ReadKey();
