2. Just double.Parse wouldn't work, because it actually wants the number as 2,0 instead of 2.0
You can use this:
double.Parse("2.0", System.Globalization.NumberStyles.AllowDecimalPoint, System.Globalization.NumberFormatInfo.InvariantInfo);
Also, don't forget to check it is really something like 2.0. A user could enter 2.a or something and your program will probably crash.

So i will show you the problem, i am parsing a double, converting to string bubt with the double format
double text = double.Parse(ScaleBox.Text, System.Globalization.NumberStyles.AllowDecimalPoint, System.Globalization.NumberFormatInfo.InvariantInfo);
string result = number[0] + "," + number[1]+ "," + number[2] + "," + number[3] + "," + text;

Also, just for future coding style: If number[] is a array of int or double or smth like that, make sure to write number[0].ToString().

int[] number = new int[15];
number[0] = int.Parse(EntryBox.Text);
number[1] = int.Parse(ModelBox.Text);
number[2] = int.Parse(SoundBox.Text);
number[3] = int.Parse(DisplayInfoExtraBox.Text);
double scale = double.Parse(ScaleBox.Text, System.Globalization.NumberStyles.AllowDecimalPoint, System.Globalization.NumberFormatInfo.InvariantInfo);
string result = number[0] + "," + number[1]+ "," + number[2] + "," + number[3] + "," + scale;
ShitBox.Text = result;
So i don't know how to handle the double so my head is exploding

Isn't there a way to make a TextField return a double or a float without any conversion?
