Hi all,
Assume that i have an enum like this.
enum TestEnum  {
    Received = 1,
    Started ,
    Finished ,
    Sent
}

I am saving this enum values as string in database. So, when i retrieve them from the database, how can i parse the string into TestEnum ? In vb. net, i can use
[Enum].Parse(GetType( TestEnum), "Started")
How to do this in D ?

you can convert an enum to a string using
myEnum.to!string

and you can similarly convert strings back to the enum using
someString.to!TestEnum

(import std.conv for both of them)

Use `to` from `std.conv`.

```
import std.conv: to;
void main() {
    assert("Received".to!TestEnum == TestEnum.Received);
}
```

Hi,
Thanks a lot. It worked. :)
