using System; using System.Collections.Generic; using System.Text; using System.Threading; namespace ATest { class A { public static void Main() { Thread t = new Thread( new ThreadStart(A)); t.Start(); Console.Read(); } private static void A() { Console.WriteLine( "不带参数 A!" ); } } } |
结果显示“不带参数 A!”
二、带一个参数创建Thread
由于ParameterizedThreadStart要求参数类型必须为object,所以定义的方法B形参类型必须为object。

using System; using System.Collections.Generic; using System.Text; using System.Threading; namespace BTest { class B { public static void Main() { Thread t = new Thread( new ParameterizedThreadStart(B)); t.Start( "B" ); Console.Read(); } private static void B( object obj) { Console.WriteLine( "带一个参数 {0}!" ,obj.ToString ()); } } } |
结果显示“带一个参数 B!”
三、带多个参数创建Thread
由于Thread默认只提供了这两种构造函数,如果需要传递多个参数,可以基于第二种方法,将参数作为类的属性传给线程。

using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;
namespace CTest
{
class C
{
public static void Main()
{
MyParam m = new MyParam();
m.x = 6;
m.y = 9;
Thread t = new Thread(new ThreadStart(m.Test));
t.Start();
Console.Read();
}
}
class MyParam
{
public int x, y;
public void Test()
{
Console.WriteLine("x={0},y={1}", this.x, this.y);
}
}
}
|
结果显示“x=6,y=9”
四、利用回调函数给主线程传递参数
我们可以基于方法三,将回调函数作为类的一个方法传进线程,方便线程回调使用。
