c# - C# 中的 CLOCKS_PER_SEC 等价物

Question

我在 C++ 中有此代码片段，但很难将其转换为 C#

clock_t now = clock();
myStartTime = start;
myTimeLimit = 5 // in seconds

for (int depth = 2; ((double)(now - myStartTime)) / (double)CLOCKS_PER_SEC < myTimeLimit; depth += 2)
{
    //
}

我应该这样做吗？

var now = DateTime.Now;
myStartTime = start;
myTimeLimit = 5;

for (int depth = 2; (now - myStartTime).TotalSeconds < myTimeLimit; depth += 2)
{

}

您可以使用 CancellationTokenSource作为实现这一目标的更好选择。例如

var clt = new CancellationTokenSource(5000);
Task.Run(() => DoSomething(clt.Token));

private static void DoSomething(CancellationToken cltToken)
{
    for (int depth = 2; !cltToken.IsCancellationRequested; depth += 2)
    {
        // . . .
    }

    if (cltToken.IsCancellationRequested) {
        // Time limit reached before finding best move at this depth
    }
}
