多线程progressBar 有关问题 急

随即数你就自己写吧。代码丑了点。实现思路丑了点。不过能达到效果Thread th1, th2, th3, th4;        int AddNum1, AddNum2, AddNum3, AddNum4;        private void button1_Click(object sender, EventArgs e)        {            int Num1 = 1;            int Num2 = 2;            int Num3 = 3;            int Num4 = 4;            AddNum1 = Num1;            AddNum2 = Num2; AddNum3 = Num3;             AddNum4 = Num4;            th1 = new Thread(new ThreadStart(delegate { ThMeod(Num1); }));            th1.Start();            th2 = new Thread(new ThreadStart(delegate { ThMeod(Num2); }));            th2.Start();            th3 = new Thread(new ThreadStart(delegate { ThMeod(Num3); }));            th3.Start();            th4 = new Thread(new ThreadStart(delegate { ThMeod(Num4); }));            th4.Start();        }        private void ThMeod(int Num1)        {            Invoke(new Brun(Badd), new object[] { AddNum1 });            Invoke(new Brun(Badd), new object[] { AddNum2 });            Invoke(new Brun(Badd), new object[] { AddNum3 });            Invoke(new Brun(Badd), new object[] { AddNum4 });        }        private delegate void Brun(int Num1);        private void Badd(int Num1)        {            timer1.Start(); timer2.Start(); timer3.Start(); timer4.Start();        }        private void timer1_Tick(object sender, EventArgs e)        {            progressBar1.Value += AddNum1;            if (progressBar1.Value == 100)            {                timer1.Stop();            }        }        private void timer2_Tick(object sender, EventArgs e)        {            progressBar2.Value += AddNum2;            if (progressBar2.Value == 100)            {                timer2.Stop();            }        }        private void timer3_Tick(object sender, EventArgs e)        {            progressBar3.Value += AddNum3;            if (progressBar3.Value == 100)            {                timer3.Stop();            }        }        private void timer4_Tick(object sender, EventArgs e)        {            progressBar4.Value += AddNum4;            if (progressBar4.Value == 100)            {                timer4.Stop();            }        }
