Question

I have a project that reads some data from xml file
Convert.ToDouble metod works wrong.
it converts 0.05 as 5.
is there any idea to solve this problem?

this is my ReadDataFromXml method:

public static List<double> XmldenTabanDegerleriniOku(string ID)
{

    string ayarDir = System.Environment.CurrentDirectory + "\\Ayarlar";
    string Dosya = ayarDir + "\\YuzeyBoyutlari.xml";
    XmlDocument doc = new XmlDocument();
    doc.Load(Dosya);

    XmlNodeList holList = doc.GetElementsByTagName("HOL");
    List<double> tabanDegerleri = new List<double>();
    foreach (XmlNode node in holList)
    {
        XmlElement holElement = (XmlElement)node;

        if (node.Attributes["ID"].Value == ID) { 
            double uzunluk =Convert.ToDouble(holElement.GetElementsByTagName("uzunluk")[0].InnerText.Replace('.',','));
            double genislik =Convert.ToDouble(holElement.GetElementsByTagName("genislik")[0].InnerText.Replace('.',','));
            double cizgilerArasiMesafe = Convert.ToDouble(holElement.GetElementsByTagName("cizgilerArasiMesafe")[0].InnerText.Replace('.', ','));
            tabanDegerleri.Add(uzunluk);
            tabanDegerleri.Add(genislik);
            tabanDegerleri.Add(cizgilerArasiMesafe);
            break;
        }


    }
    return tabanDegerleri;
}

Don’t use Convert.ToDouble then: use XmlConvert.ToDouble. I believe that effectively uses the invariant culture (as XML documents conveying data shouldn’t be culture-specific in that sense).

EDIT: I hadn’t noticed that you were manually replacing ‘.’ with ‘,’ – so when you say that “it is converting 0.05 as 5” you really mean “it is converting 0,05 as 5”. You should use XmlConvert and stop messing with the data yourself.
