convert string value to enum

[Toska]

Hi,
Wonder how I can convert a string value to enum value.


Code
-------------------
<appSettings>
<add key="BaseType" value="Sand" />
</appSettings>

-------------------


Code
-------------------

enum BaseType : int
{
Sand,
Water,
Earth
}

public static BaseType GetBaseType()
{
object dbtype = HttpContext.Current.Cache["basetype"];

if(dbtype == null)
{
BaseType idbtype = (BaseType)ConfigurationSettings.AppSettings["BaseType"];
HttpContext.Current.Cache["basetype"] = idbtype;
return idbtype;
}

return (BaseType)dbtype;
}
