                }

                Thread t1, t2;

                                        Thread.Sleep(1000);
                                }
                                else
                                {
                                        js1();
                                }
                        }
                        
                }

                private void th2()
                {
                        while (true)
                        {
                                if (this.InvokeRequired)
                                {
                                        this.Invoke(new weituo(js2));
                                        Thread.Sleep(1000);
                                }
                                else
                                {
                                        js1();
                                }
                        }

                }

                private void js1()
                {
                        int i = 1;
                        if (i == 1)
                        {
                                listBox1.Items.Add("这里是线程 1");
                        }    
                }

                private void js2()
                {
                        int i = 1;
                        if (i == 1)
                        {
                                listBox1.Items.Add("这里是线程 2");
                        }
                }
        }
}

这里包含了多线程的所有用法。

在这里我没有写判断，大家自己加进去好了，很简单。
