关于两个button中调用线程对象的问题

[yunhaiC QQ654777694]

private void button1_Click(object sender,MouseEventArgs e)
{
  Thread th = new Thead(new ThreadStart(step_for));
  th.Start();
}

void step_for()
{
  for(int i=1;i<=20;i++)
  {
  ........//省略
  }
}

private void button2_MouseDown(object sender,MouseEventArgs e)
{
 th.Abort();   //名称th不存在于目前内容中，请问怎么解决}

th并不是在button2_MouseDown(object sender,MouseEventArgs e)中声明的，当然会抛出这个异常了

所以我想问下怎么解决
如果在class开头new一个线程，那它又会报错，因为这个方法step_for()的问题

private void button1_Click(object sender,MouseEventArgs e)
{
Thread th = new Thead(new ThreadStart(step_for));
th.Start();
}

改成

private Thread th = new Thead(new ThreadStart(step_for));
private void button1_Click(object sender,MouseEventArgs e)
{
th.Start();
}

改成

private void button1_Click(object sender,MouseEventArgs e)
{
th.Start();

同意!

那样绝对会提示当前上下文不存在step_for

Thread th = new Thead(new ThreadStart(step_for));

改成

private Thread th = new Thead(new ThreadStart(step_for));
private void button1_Click(object sender,MouseEventArgs e)
{
th.Start();
}

栏位初始设定式或无法参考非静态栏位，方法或属性'step_for()'

帮顶一下，写了半天也没写出来

        private Thread th = null;

        private void button1_Click(object sender, EventArgs e)
        {
            th = new Thread(new ThreadStart(step_for));
            th.Start();
        }

        private void button2_Click(object sender, EventArgs e)
        {
            if (th != null)
            {
                th.Abort();
            }
        }
