Config helper ysing generics

[Badgers]

Hi,

I have the following bit of code:

private static T GetConfigValue2<T>(string key)
{
int value = 0;
if (!string.IsNullOrEmpty(ConfigurationManager.AppSettings[key]))
{
int.TryParse(ConfigurationManager.AppSettings[key], out value);
}
return value;
}

I want to do an int.tryparse for int values, does anyone know how to test the type T for an int???

Also how to make the return of the function generic as the values would be string, int and double.

Thanks

private static T GetConfigValue2<T>(string key)
{
   var value = ConfigurationManager.AppSettings[key];
   return value == null 
                  ? default (T)
                  : (T)Convert.ChangeType(value, typeof(T));
}
