I have few enums in my game, and I know that I can give them integer values:  
enum DamageType{  
physical = 0,  
magic = 1,  
fire = 2,  
…  
}  
and I know I can use these integer values by using (int)DamageType.physical (by putting an (int) before the enum). However, **how can I do it the other way around - I get the enum’s value by using an int**?  
And **can I get the amount of members the enum contains with a function**? (something like getting an array’s length)?  
Or perhaps **can I loop trough each member (by using for or while)**?

You simply cast the integer value to your enum:

```csharp
DamageType dt = (DamageType)yourIntValue;

```

To get the length of an enum you use System.Enum like so:

```csharp
int enumLength = System.Enum.GetValues( typeof( DamageType )).Length;

```
