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!”
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!”
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”
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。
