C#中使用德语十进制分隔符对双值进行XML反序列化

本文介绍了C#中使用德语十进制分隔符对双值进行XML反序列化的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试从德语" xml字符串反序列化Movie对象:

i'm trying to deserialize a Movie object from a "German" xml string:

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);

此处是Movie类以供参考:

[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>作为1.99，它就可以完美地工作.当我使用德语德语小数分隔符1,99时，它不再起作用.

as long i put a the <price> as 1.99 it works perfectly. when i use the German German decimal separator 1,99 it's not working anymore.

推荐答案

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

As already noted, that simply isn't a valid way of representing a numeric value in XML. It is fine for a string though. You could do:

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

其中"..."代表您选择的格式说明符和CultureInfo

Where "..." represents your choice of format specifier and CultureInfo
