同樣數值都是 100000

foxpro 速度 快了 c# 千里，c# 難道有寫錯嗎？

如真是這樣差，那c#效能就 ?

我有 弄了一段
https://www.youtube.com/watch?v=Hui-xLlqbOw
----------------------------------
C# 2017

private void button1_Click(object sender, EventArgs e)
{

for (int i3 = 0; i3 <= 100000; i3++)
{
label1.Text = i3.ToString();
label1.Update();
// Text = i3.ToString();
}
}
========================
foxpro

Now=second()
For i = 1 to thisform.text1.value
ThisForm.Label5.caption = str (i)
Endfor
new = second()
thisform.caption = "共 花" + str(new-now) + " 秒"
thisform.text1.setfocus

================
c# 再改成這樣 就很快 ，label1不顯示跑

private void button1_Click(object sender, EventArgs e)
{
int a=0;
for (int i3 = 0; i3 <= 100000; i3++)
{
a ++;
}
MessageBox.Show(a.ToString());
}

=====================

12/2 號 改用 1000000000 test

意外 c# 很快結束，foxpro 跑很久

foxpro
--------------
a=0

Now=second()
For i = 1 to thisform.text1.value
a=a+1
Endfor
new = second()
thisform.caption = "共 花" + str(new-now) + " 秒"

messagebox (str(a))
thisform.text1.setfocus

你在youtube 的說明,讓人看不懂?
-->foxpro & c# 無意間 比較卻發現 for 速度跟本不能比！
究竟是誰比誰快?
