C#中將小寫金額轉換為大寫金額 性能比較 循環int.MaxValue / 1000次我用了14秒，他的

 

看到Danny.lis 寫的C#中將小寫金額轉換為大寫金額 ，想起已經我也弄個一個類似功能，但那時候我畢業也好幾個月，但我感覺還是比他的性能要好點，於是把那時候的代碼找了出來，貼上來大家測試測試

public static string GetToZHString(float value)

        {

            string str = "";

            string[] s = { "分", "角", "元", "十", "百", "千", "萬", "十", "百", "千", "億", "十", "百", "千" };

            char[] c = { '零', '壹', '貳', '三', '肆', '伍', '陸', '柒', '捌', '玖' };

            bool b = value < 0;

            if (b)

            {

                value = 0 - value;str = "負";

            }

            string temp = value.ToString("#0.00").Replace(".", string.Empty);

 

            int count = temp.Length - 1;

            for (int i = 0; i <= count; i++)

            {

                str += c[int.Parse(temp[i].ToString())] + s[count - i];

            }

            return str;

        }

 

我在把他的代碼貼出來

我想應該還是我的性能會比較好吧? 因為我只會點C#所有自己也不怎麼會測試性能 就簡單的循環了int.MaxValue/1000次 顯示我的比他快6秒左右

10月25日更新

看到3、6樓的回復我有點失望，於是為了證明測試性能我把他改寫成與Danny.lis一樣的結果在拿出來測試大家請看結果

這是代碼  不過加班加到剛剛才下班所有代碼寫的就有點凌亂了 沒整理 大家賴點心吧
