c# - C#中使用德语十进制分隔符对双值进行XML反序列化

我正在尝试从“德语” xml字符串反序列化Movie对象:

string inputString = "<?xml version=\"1.0\"?>"
    + "<movie title=\"Great Bollywood Stuff\">"
    + "<rating>5</rating>"
    + "<price>1,99</price>" // <-- Price with German decimal separator!
    + "</movie>";

XmlSerializer movieSerializer = new XmlSerializer(typeof(Movie));
Movie inputMovie;

using (StringReader sr = new StringReader(inputString))
{
    inputMovie = (Movie)movieSerializer.Deserialize(sr);
}
System.Console.WriteLine(inputMovie);

这里是Movie类供引用:

[XmlRoot("movie")]
public class Movie
{

    [XmlAttribute("title")]
    public string Title { get; set; }

    [XmlElement("rating")]
    public int Rating { get; set; }

    [XmlElement("price")]
    public double Price { get; set; }

    public Movie()
    {

    }

    public Movie(string title, int rating, double price)
    {
        this.Title = title;
        this.Rating = rating;
        this.Price = price;
    }

    public override string ToString()
    {
        StringBuilder sb = new StringBuilder("Movie ");
        sb.Append("[Title=").Append(this.Title);
        sb.Append(", Rating=").Append(this.Rating);
        sb.Append(", Price=").Append(this.Price);
        sb.Append("]");

        return sb.ToString();
    }

}

只要我把<price>设为1.99，它就可以完美地工作。当我使用德语德语小数点分隔符1,99时，它不再起作用。

请指教

最佳答案

如前所述，这根本不是用XML表示数字值的有效方法。不过，对于字符串来说是很好的。您可以这样做:

[XmlIgnore]
public decimal Price {get;set;}

[XmlElement("price")]
public string PriceFormatted {
    get { return Price.ToString(...); }
    set { Price = decimal.Parse(value, ...); }
}

其中“...”代表您对格式说明符和CultureInfo的选择
