How can I get a enum value

Jun 04, 2007 05:53 PM|LINK

I have this enum

public enum CategoriesType : int

{

Operations = 1001,

Personnel = 1002,

Safety = 1003

}

I then define:

CategoriesType mycategory = CategoriesType.Operations;

How can I get 1001 that i have define in my enum, so far I only figure how to get Operations but not the actual value

```
int x = (int) Enum.Parse(typeof (CategoriesType), Enum.GetName(typeof (CategoriesType), mycategory));
```

you have to convert value into integer.
```
TRY THIS CODE: 
```
```
int value = (int) Enum.Parse(typeof (CategoriesType), Enum.GetName(typeof (CategoriesType), mycategory));
```

You cannot use 'value' as it's one of the protected keyword in c# and vb.net

To get the value of the enum, you just have to cast it to the value type, like this:
```
int x  = (int)CategoriesType.Operations;
```

Awesome. This returns the value of Enum. Thanks jackyang.

int x = (int) Enum.Parse(typeof (CategoriesType), Enum.GetName(typeof (CategoriesType), mycategory));

lol @ the convoluted way of casting an enum to an int, this is ALL you need:

(int) mycategory;

Where you would use Enum.Parse is if you wanted to determine an Enum representation from say a string, eg:
```
enum Colors { Red = 1, Green = 2, Blue = 4, Yellow = 8 };


Colors myOrange = (Colors)Enum.Parse(typeof(Colors), "Red, Yellow");
```
Whereas...

int x = (int) Enum.Parse(typeof (CategoriesType), Enum.GetName(typeof (CategoriesType), mycategory));

Is taking an enum, finding its name, then parsing the name to find the enum AGAIN, and then (finally) casting the original enum to an int.
