Converting string to enum?

Question

I have the following enum in my class:

 public enum InventoryType { EQUIP = 1, USE = 2, SETUP = 3, ETC = 4, CASH = 5, EVAN = 6, TOTEMS = 7, ANDROID = 8, BITS = 9, MECHANIC = 10, HAKU = 11, EQUIPPED = -1 }

Now, I have a field:

 public InventoryType InventoryType { get; private set; }

I load the data from MySql. MySql's column of type has the string that is the InventoryType. How can I convert the string I get to the enum InventoryType?

I tried:

this.InventoryType = reader.GetString("type");

But of course, that doesn't work, because it's getting a string and required an InventoryType. What can I do to convert it? Thanks.

You can parse it using Enum.TryParse:

InventoryType inventoryType; if(Enum.TryParse(reader.GetString("type"), out inventoryType)) { //use inventoryType } else { //not valid }

You should be able to leave out <InventoryType>, since it can be inferred from the inventoryType variable.

You can use Enum.Parse to parse your string back to Enum value -

this.InventoryType = (InventoryType)Enum.Parse(typeof(InventoryType), reader.GetString("type"));

Also, use Parse if you are sure the value will be valid; otherwise use TryParse.

@RohitVats you also missed the ) after InventoryType.

It may be obvious from the samples, but just in case: Parse will throw an exception if there isn't a match. TryParse takes an out parameter and returns a bool indicating success or failure.

@Rob - Indeed. That's how it works. Hope that's obvious. Although mentioned in the answer.

Try this:-

this.InventoryType= (InventoryType) Enum.Parse( typeof(InventoryType), reader.GetString("type") );
