What was I thinking

That's pretty poor refactoring, it should have been:
interface IBooleanConverter {
bool BooleanToBoolean(bool value);
}class BooleanConverter : IBooleanConverter {
public BooleanToBoolean(bool value) {
return value == true ? true : false;
}
}interface IBooleanConverterFactory {
IBooleanConverter CreateBooleanConverterFactory();
}class ConfigurationBooleanConverterFactory : IBooleanConverter {
public IBooleanConverter CreateBooleanConverter() {
return (IBooleanConverter)
Activator.CreateInstance(ConfigurationManager.AppSettings["Types.BooleanConverter"]);
}
}static class BooleanConverterFactoryFactory {
public IBooleanConverterFactory CreateBooleanConverterFactory() {
return (IBooleanConverterFactory)
Activator.CreateInstance(ConfigurationManager.AppSettings["Types.BooleanConverterFactory"]);
}
}// ...
return BooleanConverterFactoryFactory.CreateBooleanConverterFactory().CreateBooleanConverter().BooleanToBoolean(someBooleanVariable == true ? true : false);
It is clear that this is more maintainable. There is currently this method in our code-base because some [one] of our developers is so bad that we need to hold his hand through everything:
public static T As(this object obj) {
return obj as T;
}Yes guys, an extension method that replicates a keyword.

While editing a much tweaked process that I wrote, I found this T-SQL:
DECLARE @NumDays INT;
SELECT @NumDays =
CASE
WHEN @Client = 'Client1' THEN @DaysBack
WHEN @Client = 'Client2' THEN @DaysBack
ELSE @DaysBack
END;This is what happens when you go from actual numbers to a variable, without checking the code. :-O
This could make a good business sense when some decisions for different clients have not been made. Make the code structure ready and wait for the changes. I recently worked on a project in which different user role was supposed to have a different permission. But the decision was not made. Therefore all roles were assigned the same permission during development. Sometimes, the decision is never made. Several years later, when you look at the code, you would question why you did that.

You mean they missed the totally obvious contraction to
return someBooleanVariable ? true : false
They should hang their head in shame!

You're not following good form. You should use CONSTANTS for things that like.
return someBooleanVariable ? Boolean.Parse(Boolean.TrueString) : Boolean.Parse(Boolean.FalseString);
;)

You mean
return someBooleanVariable.ToString() == Boolean.TrueString? Boolean.Parse(Boolean.TrueString) : Boolean.Parse(Boolean.FalseString);
Right?

Good call. :D

It took this long to get this simple return?

Not good enough:
if (((Boolean)someBooleanVariable).equals(true)) {
return someBooleanVariable == true ? someBooleanVariable : false;
} else {
return someBooleanVariable == false ? someBooleanVariable : true;

Ah, now I see what people mean by maintainable code - code that will require maintenance, and hence pay the bills for years to come. Genius.
