task中有個(gè)需求幢尚，需要根據(jù)身份證號(hào)獲取用戶的星座，我首先想到根據(jù)日期匹配日期區(qū)間翅楼，代碼寫起來(lái)不太順利尉剩。查資料后，感覺這個(gè)思路不錯(cuò)毅臊，將日期的比對(duì)轉(zhuǎn)換為浮點(diǎn)數(shù)比對(duì)理茎。
public static string GetAtomFromBirthday(DateTime birthday, ref string Constellationtxt)
{
float birthdayF = 0.00F;
if (birthday.Month == 1 && birthday.Day < 20)
{
birthdayF = float.Parse(string.Format("13.{0}", birthday.Day));
}
else
{
birthdayF = float.Parse(string.Format("{0}.{1}", birthday.Month, (birthday.Day > 9 ? birthday.Day.ToString() : "0" + birthday.Day)));
}
float[] atomBound = { 1.20F, 2.20F, 3.21F, 4.21F, 5.21F, 6.22F, 7.23F, 8.23F, 9.23F, 10.23F, 11.21F, 12.22F, 13.20F };
string[] atoms = { "水瓶座", "雙魚座", "白羊座", "金牛座", "雙子座", "巨蟹座", "獅子座", "處女座", "天秤座", "天蝎座", "射手座", "魔羯座" };
string[] atomscode = { "11 (陽(yáng)歷：1.20~2.18)", "12 (陽(yáng)歷：2.19~3.20)", "01 (陽(yáng)歷：3.21~4.19)",
"02 (陽(yáng)歷：4.20~5.20)", "03 (陽(yáng)歷：5.21~6.21)", "04 (陽(yáng)歷：6.22~7.22)",
"05 (陽(yáng)歷：7.23~8.22)", "06 (陽(yáng)歷：8.23~9.22)", "07(陽(yáng)歷：9.23~10.23)",
"08 (陽(yáng)歷：10.24~11.22)", "09 (陽(yáng)歷：11.23~12.21)", "10 (陽(yáng)歷：12.22~1.19)" };
string ret = string.Empty;
for (int i = 0; i < atomBound.Length - 1; i++)
{
if (atomBound[i] <= birthdayF && atomBound[i + 1] > birthdayF)
{
ret = atomscode[i];
Constellationtxt = atoms[i];
break;
}
}
return ret;
}
但有個(gè)坑，需要注意日期號(hào)碼為個(gè)位數(shù)時(shí)褂微，應(yīng)在前面加0.（我已因此被噴過了功蜓。）
