当我创建一个包含方法的数组时,stopwatch.elapsedMilliseconds 总是返回 0。
例子:
int[] methods = {method1(), method2()};
Stopwatch sw = new Stopwatch();
sw.Start();
int val = methods[1];
sw.Stop();
Console.WriteLine("It took {0} ms", sw.ElapsedMilliseconds);
// Output: "It took 0 ms"
当我直接调用该方法时,秒表可以正常工作:
Stopwatch sw = new Stopwatch();
sw.Start();
method1();
sw.Stop();
Console.WriteLine("It took {0} ms", sw.ElapsedMilliseconds);
// Output: "It took x ms"
我究竟做错了什么?
编辑:实际主要代码:
static void Main(string[] args)
{
Stopwatch t = new Stopwatch();
Func<int>[] problems = new Func<int>[] { problem5, problem6 };
for (int i = 0; i < problems.Length; i++)
{
t.Restart();
Console.WriteLine("Solution to {0} is: {1}", problems[i].Method.Name , problems[i]());
t.Stop();
Console.WriteLine("It took {0} ms ", t.ElapsedMilliseconds);
}
Console.ReadKey();
}
输出:
