c# - 为什么我不能使用 stopwatch.Restart()？

Question

我正在尝试在秒表实例上调用 Restart()，但在尝试调用它时出现以下错误:

Assets/Scripts/Controls/SuperTouch.cs(22,59): error CS1061: Type System.Diagnostics.Stopwatch' does not contain a definition for
Restart' and no extension method Restart' of type
System.Diagnostics.Stopwatch' could be found (are you missing a using directive or an assembly reference?)

这是我的代码:

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using System.Diagnostics;

namespace Controls
{

    public class SuperTouch
    {
            public Vector2 position { get { return points [points.Count - 1]; } }
            public float duration { get { return (float)stopwatch.ElapsedMilliseconds; } }
            public float distance;
            public List<Vector2> points = new List<Vector2> ();

            public Stopwatch stopwatch = new Stopwatch ();

            public void Reset ()
            {
                    points.Clear ();
                    distance = 0;
                    stopwatch.Restart ();
            }
    }
}

我猜您使用的是 4.0 之前的框架，这意味着您必须使用 Reset 和 Start 而不是 Restart。
