我来这里是因为我使用这段代码有一个奇怪的行为：但在此之前，我知道这样做是一个非常糟糕的做法，所以它甚至没有在现实中使用我只是想了解幕后发生的事情但我对此知之甚少。

这是有问题的代码：

int worker = 0;
int io = 0;
Console.WriteLine($"Worker thread {worker} Io thread {io}");
ThreadPool.GetAvailableThreads(out worker, out io);
ThreadPool.GetMaxThreads(out var workerThreadsMax, out var completionPortThreadsMax);

Console.WriteLine($"Worker thread {workerThreadsMax - worker} Io thread {completionPortThreadsMax - io}");
for (int i = 0; i < 100; i++)
{
                
    Task.Run(() =>
    {
        Console.WriteLine(Thread.CurrentThread.ManagedThreadId + " - Running thread");
        ThreadPool.GetAvailableThreads(out var worker2, out var io2);
        ThreadPool.GetMaxThreads(out var workerThreadsMax2, out var completionPortThreadsMax2);
        Console.WriteLine($"{Thread.CurrentThread.ManagedThreadId} - Worker thread {workerThreadsMax2 - worker2} Io thread {completionPortThreadsMax2 - io2}");
