Unity3D研究院之获取某个方法执行的时间

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

public class NewBehaviourScript : MonoBehaviour {

	void Start () {
	
		float t = Time.time;
		TestMethod();
		UnityEngine.Debug.Log(string.Format("total: {0} ms",Time.time - t));



		Stopwatch sw = new Stopwatch();
		sw.Start();
		TestMethod();
		sw.Stop();
		UnityEngine.Debug.Log(string.Format("total: {0} ms",sw.ElapsedMilliseconds));


		Profiler.BeginSample("TestMethod");
		TestMethod();
		Profiler.EndSample();
	}


	void TestMethod()
	{
		for(int i =0; i < 10000000; i++)
		{
		}
	}
