Question

I have class named “config” that have private string variable named “param”.

I need to get from “config” class “param” variable sometimes as int type sometimes as bool type or string.

As I understand I need create 3 properties in config class,each property have to convert type, as follow:

The first property converts string to int, the second converts string to bool, the third property gets me the string value.

The class should look something like this:

class Config
{
    private string param; 

   public int ParamAsInt
  {
    get 
    { 
        return int.Parse(param); 
    }
  }

  public bool ParamAsBool
  {
    get 
    { 
        return bool.Parse(param); 
    }
  }

  public string ParamAsString
  {
    get 
    { 
        return param; 
    }
  }

}

But I don’t know how can those properties be used in accordance to the variable type that I want to get out of class.

This code won’t compile – int and such are reserved keywords and cannot be used as identifiers. You can either try naming your properties something like Int32Value, StringValue, etc., or try this:

public static implicit operator bool (Config config)
{
    return bool.Parse(config.param);
}

public static implicit operator int (Config config)
{
    return int.Parse(config.param);
}

This will allow for much cleaner code:

Config c = GetConfig("foo");
var isFeatureEnabled = false || c;
var spacing = 23 + GetConfig("bar");
