強制枚舉以獲取與其關聯的值？

Question

我有這樣一個枚舉：

public enum BlahType 
{ 
    blahA = 1, 
    blahB = 2, 
    blahC = 3 
} 

如果我有值「blahB」字符串，是有可能丟反對枚舉BlahType獲得價值2？

Answer 1

您可以使用Enum.Parse方法，然後強制轉換爲int。

Answer 2

用途：

BlahType yourEnumValue = (BlahType) Enum.Parse(typeof(BlahType), "blahB"); 

然後

int yourIntValue = (int) yourEnumValue; 

Answer 3

public void EnumInstanceFromString() 
{ 

DayOfWeek wednesday = (DayOfWeek)Enum.Parse(typeof(DayOfWeek), "Wednesday"); 
DayOfWeek sunday = (DayOfWeek)Enum.Parse(typeof(DayOfWeek), "sunday", true); 
DayOfWeek tgif = (DayOfWeek)Enum.Parse(typeof(DayOfWeek), "FRIDAY", true); 

lblOutput.Text = wednesday.ToString() + 
        ". Int value = " + 
        (int)wednesday).ToString() + "<br>"; 

lblOutput.Text += sunday.ToString() + 
        ". Int value = " + 
        ((int)sunday).ToString() + "<br>"; 

lblOutput.Text += tgif.ToString() + 
        ". Int value = " + 
        ((int)tgif).ToString() + "<br>"; 

} 

Answer 4

enum test 
{ 
    VAL1, 
    VAL2 
} 

static void Main(string[] args) 
{ 
    test newTest = (test)Enum.Parse(typeof(test), "VAL2"); 
    Console.WriteLine(newTest.ToString()); 
} 

Answer 5

使用此代碼...

BlahType blah = Enum.Parse(typeof(BlahType), "blahB"); 

Answer 6

正如一些OT上述她想要使用：

 BlahType myEnum = (BlahType)Enum.Parse(typeof(BlahType), "blahB"); 
     int myEnumValue = (int)myEnum;
