Parse strings to double with comma and point (14 answers)

Closed 9 years ago.

I am trying to read a number from the console, but if it is input via comma (ex. 2,56), it cannot be parsed successfully. It can be parsed only if it is input like this: 2.56 How can I change that? Here is a sample code:

       if (double.TryParse(stringElements[i], out doubleNum))
                {
                    averageTime.Add(doubleNum);
                }

Answer 1

replace the comma by '.' like this :

save your number in variable X , then

if (double.TryParse((X).Replace(",", "."), out tmp))
{

}

Answer 2

replace with "."

Convert.ToDouble("2,56".Replace(",", "."));
