同样的1000万数组的排序算法为什么C# 用时0.5秒,而C语言用时0.6秒?

同样的1000万数组的排序算法为什么C# 用时0.5秒,而C语言用时0.6秒?

C语言 算法库

C#调用范例:
[DllImport("BwsyqIndex.dll")]
public static extern void HzSort(int[] mi, int num_elements);

protected void Page_Load(object sender, EventArgs e)
{
int iUp = 1000000;
Random ro = new Random(10000000);
long tick = DateTime.Now.Ticks;

int[] a = new int[10000000];
for (int i = 0; i < 10000000; i++)
{
a[i] = ro.Next(10000000);
}
//开始时间
TimeSpan runTime = new TimeSpan(DateTime.Now.Ticks);

HzSort(a, 10000000);

//结束时间
TimeSpan timeNow = new TimeSpan(DateTime.Now.Ticks);
//时间间隔
TimeSpan ts = timeNow.Subtract(runTime).Duration();
Response.Write(" 用时：" + ts.TotalSeconds.ToString() + "秒 " + ts.TotalMilliseconds.ToString() + "毫秒");

}
