Question

I have a problem : I have a string containing values and I want to split them into a double array .

The input : 0.0 0.0 0.0

I have two ways but both are not working

First :

                Dim arrString As String() = line.Split(New Char() {" "c})
                Dim numbers As Double() = New Double(arrString.Length) {}
                Dim i As Integer = 0
                While i < arrString.Length
                    numbers(i) = Convert.ToDouble(arrString(i))
                    i += 1
                End While

Second :

                Dim nums As String() = line.Split(" "c)
                Dim numbers As Double() = From num In nums Select Convert.ToDouble(num)

I get a FormatExeption exeption
Please help me , its for an .obj loader

Answer 1

The current culture is likely using a different decimal separator. Use the overload of the ToDouble that takes a format provider:

Convert.ToDouble(num, CultureInfo.InvariantCulture)

(The InvariantCulture property returns a neutral culture info that is based on english settings, so it uses period as decimal separator.)
