smart way to detect if System.Boolean true or false

[OriginalGriff]

I'm not sure I trust computers that much. Can I suggest an improvement?

            string valueStr = value.ToString();
            if (valueStr.Equals("true", StringComparison.CurrentCultureIgnoreCase))
            {
                PDFIncludeWatermark\_ = "true";
            }
            else if (valueStr.Equals("false", StringComparison.CurrentCultureIgnoreCase))
            {
                PDFIncludeWatermark\_ = "false";
            }
            else
            {
                PDFIncludeWatermark\_ = "maybe";
            }

Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together. Manfred R. Bihy: "Looks as if OP is learning resistant."

You're right, never, never rely on compiler. Damn machines :) If you need a job done, do it yourself.

[OriginalGriff]

Oh, I trust the compiler. It's reality I don't trust.:~

Happy debugging! Internationalization will make you happy. I experienced that a long time ago. See also my message in the Hall of Shame: http://www.codeproject.com/feature/HallOfSHame.aspx?msg=3432553#xx3432553xx[^]

The else section should return "filenotfound" I believe! ;P

else
{
PDFIncludeWatermark_ = "filenotfound";
}

FTFY :-D

I disagree: the concepts of truth and falsehood do not have anything to do with file systems! However, in the real world I doubt the existence of "absolute truth" and "absolute falsehood" so a "maybe" response seems reasonable... :laugh:

eheh, you are right. Anyway, I was just quoting one of the most famous WTF: http://thedailywtf.com/Articles/What_Is_Truth_0x3f_.aspx[^] :D

Not seen that before - thanks!

Dang! Beat me to it. Marking it as "news" is pretty hilarious.

Dear VUnreal, Please find below a simplified code segment that may help you in achieving your code in one line using a helper class. please feel free to add additional checks and safeguards, and rewrite the helper as an extension to the string class.

string valueStr = value.ToString();
TruthChecker tc=new TruthChecker();
// now notice how simple: we do not use 'if', just call our helper once:
PDFIncludeWatermark_ = tc.CheckIfTrue();

class TruthChecker
{
    private static List<string> \_truths = null; // static - optimaze time as the calculation is only done if needed and even so , only once!
    List<string> Truths { get { return \_truths!=null ? \_truths : (\_truths = FindAllTruths() ); } }

    TruthChecker() {
    }

    private static List<string> FindAllTruths() {
         List<string> allTruths = new List<string>();
         char\[\] t = {'t','r','u','e'};
         for(int i=0;i<Math.Pow(2,t.Length); i++) {
            StringBuilder sb = new StringBuilder();
            for(int j=0; j<t.Length; j++) {
                int k = (i>>j)&1;
                sb.Append(t\[j\]+('A'-'a')\*k);
            }
            allTruths.Add(sb.ToString());
        }
        return allTruths;
    }

    public string CheckIfTrue(string tru)
    {
        try {
            var v = 
                from t in Truths
                where t == tru
                select t;

            if (v.ElementAt(0).ToString().Length == "true".Length) {
                return "true";
            }
        } catch (Exception ex) {
            tru = ex.Message;
        }
        return "false";
    }
}

depends what type of programming style you're into. Some might find the mentioned method easier/simpler to read/understand.
