If I had the value : "dog" and the enumeration:
public enum Animals
{
dog = 0 ,
cat = 1 ,
rat = 2
}
how could I get 0 for the value "dog" from Animals ?
EDIT:
I am wondering if there is index like acces. More commonn : how can I get the integer for string value.
Just cast your enum value to integer:
Animals animal = Animals.dog;
int value = (int)animal; // 0
EDIT: if it turns out that you have name of enum value, then parse enum value and cast it to integer:
int value = (int)Enum.Parse(typeof(Animals), "dog");
You can either cast it to Int, or iterate over all values using the Enum.GetValues Method which retrieves an array of the values of the constants in a specified enumeration.
To answer your question "how can I get the integer for string value":
To convert from a string into an enum, and then convert the resulting enum to an int, you can do this:
public enum Animals
{
dog = 0,
cat = 1,
rat = 2
}
...
Animals answer;
if (Enum.TryParse("CAT", true, out answer))
{
int value = (int) answer;
Console.WriteLine(value);
}
By the way, normal enum naming convention dictates that you should not pluralize your enum name unless it represents flag values (powers of two) where multiple bits can be set - so you should call it Animal, not Animals.
What about: var r = (int)Animals.dog
