ThreadPool.SetMinThreads(50, 50);

List<Match> Combos = new Regex("^(.{5,}):(.{6,})$", RegexOptions.Multiline).Matches(File.ReadAllText(ofd.FileNames[0])).OfType<Match>().ToList();
var query = Combos.ToObservable().SelectMany(s => Observable.Start(() => new
{
grab = checkall(s.Groups[1].Value.Replace("\n", "").Replace("\r", ""), s.Groups[2].Value.Replace("\n", "").Replace("\r", ""))
})).ObserveOn(this).Do(x =>
{
try
{
TotalChecked.Text = "Tested: " + (int.Parse(TotalChecked.Text.Substring(7)) + 1).ToString();
progressBar2.Value = (int)Math.Round((double)(100 * int.Parse(TotalChecked.Text.Substring(7))) / Combos.Count);
}
catch (Exception)
{
TotalChecked.Text = "Tested: " + (int.Parse(TotalChecked.Text.Substring(7)) + 1).ToString();
progressBar2.Value = (int)Math.Round((double)(100 * int.Parse(TotalChecked.Text.Substring(7))) / Combos.Count);
}
});
query.ToArray().ObserveOn(this).Subscribe(x =>
{
CheckButton.Location = new Point(CheckButton.Location.X + 31, 9);
CheckButton.Width -= 31;
});
上面的代码在文本文件上使用正则表达式,然后执行一个函数。 它工作正常,但现在我希望它执行多个DIFFERENT函数,并且只允许其中一些函数设置一定数量的线程。
例如:
var query = Combos.ToObservable().SelectMany(s => Observable.Start(() => new
{
grab = checkall(s.Groups[1].Value.Replace("\n", "").Replace("\r", ""), s.Groups[2].Value.Replace("\n", "").Replace("\r", "")),
//This one should be LIMITED to only 5 threads MAX!
grab2 = checktwo(Hi, Hello)
}))
在上面的代码中,我添加了grab2
,它应该分配最多5个线程。
说实话,我不知道如何执行这样的方法。 任何帮助将不胜感激。

如果您需要某些代码仅由n
个帖子执行,则需要semaphore,在这种情况下SemaphoreSlim
就够了
// 5 threads to run in parallel, all 5 can start immidiately
var semaphore = new SemaphoreSlim(5, 5);
// ...
try
{
semaphore.Wait();
//This one should be LIMITED to only 5 threads MAX!
grab2 = checktwo(Hi, Hello);
}
finally
{
// ensure the release of semaphore
semaphore.Release();
}
您甚至可以在async
methods中等待它:
await semaphore.WaitAsync();
