Foreach output into a boolean array

Question

I want to "save" my output from my foreach loop into a boolean array. What would be the easiest way to tackle that?

foreach(char est in resultss)
{
    
    int test = est - '0';
    tru = Convert.ToBoolean(test); // A Bool[] instead of Bool
    //  Console.WriteLine(tru);
}

I'm working on a binary clock and imp trying to convert a number like 22 into binary (done that) and than into a bool array.

Help us help you - share some sample data and the result you'd like to get for it. — Mureinik

var theArray = resultss.Select(x => Convert.ToBoolean(x - '0')).ToArray(); — Andy

 List<bool> list = new List<bool>();
 foreach(char est in resultss)
 {
     int test = est - '0';
     tru = Convert.ToBoolean(test);
     list.Add(tru);
 }

That's.. Perfect! Thank u a lot!

It should be list.Add(tru); C# is case sensitive...

@uk3ndt please make sure not to use that - there is rarely a good reason to use Convert. and definitely in this case Convert.ToBoolean is wrong method to use. If OP wanted to check est being '0' or not they should have simply compare it like list.Add(est != '0').

Thanks for the notice, i changed it like u said :))

You could use LINQ for this, please add reference to System.Linq and do this.

var boolArray = resultss.Select(r => Convert.ToBoolean(r - '0')).ToArray();

The second code sample is great, but what does the first code block have to do with this question?

Alexei Levenkov Over a year ago

Actually Convert.ToBoolean is awful suggestion too... Either suggest full blown stringly typed approach by converting everything to strings and parsing back on every line or for more practical approach use r => r != '0'.

@RufusL - to introduce LINQ and what it can do for you.

@AlexeiLevenkov - that's not really the question here.

I would suggest leaving out the Linq samples, as they are distracting and don't apply to the question. Simply stating that a reference to System.Linq is required should be enough.
