Re: Generics in .net 2.0

Søren,

You should be able to use generics here, on the method level. You could
declare the method as:

// Name it GetConfigValue, not getConfigValue, since
// it is a violation of the public naming guidelines.
public T GetConfigValue<T>(string key, T defaultValue)
{
// Get the value here, it should be returned as an object.
object retVal = ...;

// Cast the return value.
return (T) retVal;
}

Hope this helps.
