Generics

[Badgers]

Hi,

I am storing a number of global params in a console app populated from a db.

I'm thnking of using a list to store variable name / variable type.

The variable can obviously vary, for eg string, int etc.

What would the syntax be on the class and what syntax would you use to type the variable type generic.

Thanks

what does this have to do with webforms or asp.net?

As for access the configs. I would create a class with the properties you need to expose. no generics required.

class GolbalSettings
{
   public int Number {get;set;}
   public string String {get;set;}
   public DateTime Date {get;set;}
}

if you require a fully dynamic solution with strongly typed values it might look something like this

class GolbalSettings
{
   private HashTable table = new HashTable();

   public void Set<T>(object key, T value)
   {
       table[key] = value;
   }
   public void Get<T>(object key)
   {
       return table[key];
   }
}

class Key<T>
{
     private readonly object identifier;

     public class Key(object identifier)
     {
         this.identifier = identifier;
     }

     public T PullFrom(GolbalSettings settings)
     {
         return settings.Get(identifier);
     }

     public void PutInto(GolbalSettings settings, T value)
     {
         settings.Set(identifier, value);
     }
}

Jason,

I have a dabbled with your explanation and can't get it running properly.

Any chance you could have a revisit....

Thanks
