Question

用线程怎样调用带参数的方法？

一直报错：“coco”的重载均与委托“System.Threading.ThreadStart”不匹配
private void button1_Click(object sender, EventArgs e)
{
tCount = new Thread(new ThreadStart(coco));
tCount.Start(1000000000);//调用带参方法
}

void coco(int count)
{
double per = 0;
for (int i = 0; i < count; i++)
{
per = (double)i*100 / count;
progressBar1.Value = (int)per;//显示进度
}
}

Answer 1

定义一个全局变量啦。。
int count=0;
private void button1_Click(object sender, EventArgs e)
{
tCount = new Thread(new ThreadStart(coco));
count = 1000000000;
tCount.Start();//调用带参方法
}

void coco()
{

double per = 0;
for (int i = 0; i < count; i++)
{
per = (double)i*100 / count;
progressBar1.Value = (int)per;//显示进度
}
