I have a string array which contains 4 elements. Which looks like this.

enter image description here

How ever, when trying to do this: 

Vector newVector = new Vector(
(float)Convert.ToDouble(words[1]),
(float)Convert.ToDouble(words[2]));

I get the following error:

'Input string was not in a correct format.'

And that is because it's because the value uses a '.' but if I manually change the array to use a ',' it works. How can I easiest replace all '.' with ','.

  • Use `String.Replace` or other regional setings where decimal separtor is `.`. – BWA May 08 '17 at 11:47
  • Why do you want to use `float` typecasting? – Parth Sane May 08 '17 at 11:49
  • `Array.ConvertAll(words.Split(','), Double.Parse);` This will convert your string array to a double array. In fact I got this from another [SO][1] question. I hope this solves your problem.

Use

//(float)Convert.ToDouble(words[1]),
  (float)Convert.ToDouble(words[1], CultureInfo.InvariantCulture),

Try this...

Vector newVector = new Vector(
(float)Convert.ToDouble(words[1], CultureInfo.GetCultureInfo("en-US").NumberFormat),
(float)Convert.ToDouble(words[2], CultureInfo.GetCultureInfo("en-US").NumberFormat));
