xml Convert.ToDouble工作错误

问题描述

我有一个项目，该项目从 xml 文件
Convert.ToDouble方法读取一些数据。
会将0.05转换为5。
有解决这个问题的主意吗？

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

这是我的ReadDataFromXml方法：

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;
}

推荐答案

不要使用 Convert.ToDouble 然后：使用。我认为可以有效地使用不变文化（因为在这种意义上，XML文件传输数据不应该是特定于文化的。）

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).

编辑：我没注意到你是手动将。替换为，-因此，当您说将0.05转换为5时，您的意思是将0.05转换为5。您应该使用 XmlConvert 停止自己弄乱数据。

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.
