如何訪問枚舉類型的整數和字符串？

Question

什麼C＃代碼將輸出下面的枚舉類型的變量以下？

牙醫（2533）

public enum eOccupationCode 
     { 
      Butcher = 2531, 
      Baker = 2532, 
      Dentist = 2533, 
      Podiatrist = 2534, 
      Surgeon = 2535, 
      Other = 2539 
     } 

Answer 1

這聽起來像你想要的東西，如：

// Please drop the "e" prefix... 
OccupationCode code = OccupationCode.Dentist; 

string text = string.Format("{0} ({1})", code, (int) code); 

Answer 2

What C# code would output the following for a variable of the enum type below?

沒有鑄造，它會輸出枚舉標識符：Dentist

如果您需要訪問你需要投它是枚舉值：

int value = (int)eOccupationCode.Dentist; 

Answer 3

我猜你的意思是這

eOccupationCode code = eOccupationCode.Dentist; 
Console.WriteLine(string.Format("{0} ({1})", code,(int)code)); 
// outputs Dentist (2533) 

Answer 4

您還可以使用format stringsg，G，f，F到打印枚舉條目的名稱或d和D以打印十進制表示法：

var dentist = eOccupationCode.Dentist; 

Console.WriteLine(dentist.ToString("G"));  // Prints: "Dentist" 
Console.WriteLine(dentist.ToString("D"));  // Prints: "2533" 

...或者方便的一行：

Console.WriteLine("{0:G} ({0:D})", dentist); // Prints: "Dentist (2533)" 

這適用於Console.WriteLine，就像String.Format。
