大家好，我有这样的结构：启动线程：
Thread[] thr;
int good_auth, bad_auth, good_like, bad_like;
static object accslocker = new object();
static object limitlocker = new object();
string acc_path, proxy_path, posts_path;
int position_of_limit, position = 0;
private void button1_Click(object sender, EventArgs e)
{
button1.Enabled = false;
button2.Enabled = true;
decimal value = numericUpDown1.Value;
int i = 0;
int j = (int)(value);
thr = new Thread[j];
for (; i < j; i++)
{
thr[i] = new Thread(new ThreadStart(go));
thr[i].IsBackground = true;
thr[i].Start();
}
}
而不是功能去：
public void go()
{
while (true)
{
string acc = "";
string proxy = "";
lock (limitlocker)
{
if (position_of_limit >= int.Parse(textBox2.Text) - 1)
{
position_of_limit = 0;
if (position < posts.Count - 1)
position++;
else
{
break;
}
}
}
lock (accslocker)
{
if (accs.Count == 0)
{
break;
}
else
acc = accs.Dequeue();
}
OD od = new OD(acc);
string login = od.Auth();
if (login == "Login")
{
lock (accslocker)
{
good_auth++;
log_good_auth(good_auth);
}
string like = od.like(posts[position], textBox1.Text);
if (like == "Good")
{
lock (accslocker)
{
position_of_limit++;
good_like++;
log_good_like(good_like);
}
}
else if (like == "Failed")
{
lock (accslocker)
{
bad_like++;
log_bad_like(bad_like);
}
}
else
{
lock (accslocker)
{
bad_like++;
log_bad_like(bad_like);
}
}
}
else if (login == "Spamblock")
{
lock (accslocker)
{
bad_auth++;
log_bad_auth(bad_auth);
}
}
else if (login == "Locked")
{
lock (accslocker)
{
bad_auth++;
log_bad_auth(bad_auth);
}
}
else if (login == "Invalid")
{
lock (accslocker)
{
bad_auth++;
log_bad_auth(bad_auth);
}
}
else if (login == "Bad_proxy")
{
lock (accslocker)
{
accs.Enqueue(acc);
Proxy.proxies.Remove(proxy);
}
}
else
{
lock (accslocker)
{
accs.Enqueue(acc);
Proxy.proxies.Remove(proxy);
}
}
}
}
例如，我开始 20 个线程，当 position_of_limit 变得大于 int.Parse(textBox2.Text) - 1 所有线程都需要在下一个循环中获取下一个帖子[位置]。但是我在行字符串上收到一个异常，例如 = od.like(posts[position], textBox1.Text);
"Index was out of range. Must be non-negative and less than the size of the collection.
Parameter name: index"
如何解决这个问题呢？谢谢
