writing a .csv file - independent of the culture

Question

In German langauage- decimal seperators are , and value seperators are ";" . In English/other languages, decimal seperators are . and values seperators are ",". I want to create a .csv file indepedent of the current culture. I mean always the .csv file should have "." has decimal seperators and "," has value seperators. The code for this given below. ``` using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.IO; using System.Globalization; namespace CSV_FILE_FORMAT { class Program { static void Main(string[] args) { string aFileName = "result.csv"; FileStream aFileStream = new FileStream(aFileName, FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.None); StreamWriter m_StreamWriter = new StreamWriter(aFileStream); double[] values = new double[] { 10.5, 20.3, 30.2 }; for(int i = 0; i < values.Length;i++) { m_StreamWriter.Write(values[i].ToString(CultureInfo.InvariantCulture)); m_StreamWriter.Write(","); } } } } ``` The problem with this…

Accepted Answer

You can probably get decimal separator and list separator from the current culture.

```
CultureInfo culture = new CultureInfo(currentCultureName);
string decimalSeparator = culture.NumberFormat.NumberDecimalSeparator;
string listSeparator = culture.TextInfo.ListSeparator;
```

And, if the value being written contains any of the separators then, enclose the value within double quotes.

```
string val = values[i].ToString(CultureInfo.InvariantCulture);
if(val.Contains(decimalSeparator) || val.Contains(listSeparator))
{
    val = string.Format("\"{0}\"", val);
}
m_StreamWriter.Write(val);
m_StreamWriter.Write(listSeparator);
```

Current culture name can be something like this: "en-US" for United States of America.

Hope this helps!
