[.net]enum轉int, int轉enum
class Program
{
static void Main(string[] args)
{
//enumType to int
string enumString = "enumType1";
myEnum em = (myEnum)Enum.Parse(typeof(myEnum), enumString, false);
Console.WriteLine(enumString +"轉換變成:" + Convert.ToString((int)em));
//int to enumType
int enumInt = 2;
foreach (myEnum val in Enum.GetValues(typeof(myEnum)))
{
if (enumInt == (int)val)
{
Console.WriteLine(enumInt.ToString() + "轉換變成:" + val.ToString());
break;
}
}
Console.WriteLine("Press enter to continue");
Console.ReadLine();
}
public enum myEnum
{
enumType1 = 1,
enumType2 = 2,
enumType3 = 3
}
}
執行結果:
以上~方便enum型態與數字的轉換,做個筆記囉
ps.20171024 補充:定義enum的時候,如果沒有給每個型別一個數字,也可以純粹當成程式碼內的自定義參數,就不用每個參數都要在db設定一筆資料,例子如下:
public enum TimerType
{
PortTimer,
PortOneDayTimer,
SportWSTimer
}
