Question

我有一个相当混乱的XML结构，我需要处理并显示给最终用户。 XML结构包含有关金属条和每个条的切割的信息。目标是处理此文件，向用户显示按条形类别分组的条形列表。他们可以从此列表中选择一个条形图，其中某种网格视图将显示该条形图的切割。然后，他们可以选择剪切，该剪辑的标签信息将用于创建带有条形码和其他信息的标签。

XML的结构如下所示：

我正在寻找的结果如下所示，即左侧的树状视图和右侧的数据网格视图，显示作业中的所有切割，通过树视图选择进行过滤（仅从选定的树视图级别切割））。

GUI Layout

为了实现这一点，我尝试使用LINQ to XML将XML文件解析为我创建的类：

public List<Bars> bars = new List<Bars>();

    public class Bars
    {
        public int Bar_id { set; get; }
        public string Brand { set; get; }
        public string System { set; get; }
        public string Code { set; get; }
        public string Description { set; get; }
        public string Length { set; get; }
        public string Status { set; get; }
        public string NumBars { set; get; }
        public List<Cuts> Cuts { set;  get; }
    }

    public class Cuts
    {
        public int Cut_id { set; get; }
        public int Bar_id { set; get; }
        public string AngleL { set; get; }
        public string AngleR { set; get; }
        public string LenInn { set; get; }
        public string LenOut { set; get; }
        public string Barcode { set; get; }
        public string Description { set; get; }
        public string Status { set; get; }
        public string Label1 { set; get; }
        public string Label2 { set; get; }
        public string Label3 { set; get; }
        public string Label4 { set; get; }
    }

我实际上是在寻找有关天气的一些建议，这是处理此类项目的正确方法（LINQ to XML）。我应该使用数据集还是其他形式或数据存储。

我是XML的新手，也是关系数据库类型的东西，所以任何建议都将受到高度赞赏。提前谢谢！

既然你想要一些建议，这是一个简单的方法。在这种情况下，序列化是最简单的选择。 VS具有内置功能，可以为这种xml结构生成类代码。您可以使用Edit > Paste Special功能来实现此目的。所以你的课程看起来像;

        {
            return this.dESCField;
        }
        set
        {
            this.dESCField = value;
        }
    }

    /// <remarks/>
    public byte STAT
    {
        get
        {
            return this.sTATField;
        }
        set
        {
            this.sTATField = value;
        }
    }

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("LBL")]
    public string[] LBL
    {
        get
        {
            return this.lBLField;
        }
        set
        {
            this.lBLField = value;
        }
    }
}

然后你可以简单地反序列化;

    BODY objBody = new BODY();
    var xml = File.ReadAllText(@"C:\XMLFile2.xml");
    using (var reader = new StringReader(xml))
    {
        var serialiser = new XmlSerializer(typeof(BODY));
        objBody = (BODY)serialiser.Deserialize(reader);
    }

如果有选择，我会彻底建议使用XDocument（LINQ to XML）。创建文档并处理它们要简单得多。就个人而言，我是处理大型Xml的首选。

var result = doc.Descendants("BAR")
    .Select((e, i)=> new Bars()
            {
                Bar_id = i +1, 
                Brand  = e.Element("BRAN").Value,
                System = e.Element("SYST").Value,
                Code = e.Element("CODE").Value,
                Description = e.Element("DESC").Value,
                Length =e.Element("LEN").Value,
                Status =e.Element("STS").Value,     
                // remaining fileds
                Cuts  = e.Descendants("CUT").Select(c=> new Cuts() 
                                                 {
                                                     Cut_id =  int.Parse(c.Element("NUM").Value),
                                                     Bar_id = i+1,
                                                     AngleL = c.Element("ANGL").Value,
                                                     AngleR = c.Element("ANGR").Value,
                                                     LenInn = c.Element("IL").Value,
                                                     LenOut = c.Element("OL").Value,                                                             
                                                     Barcode = c.Element("BCOD").Value,
                                                     Description = c.Element("DESC").Value,
                                                     Status = c.Element("STAT").Value,
                                                     Label1 = c.Elements("LBL").First().Value,
                                                     Label2 = c.Elements("LBL").Skip(1).First().Value,
                                                     Label3 = c.Elements("LBL").Skip(2).First().Value,
                                                     Label4 = c.Elements("LBL").Skip(3).First().Value,

                                                 }).ToList(),
            }).ToList();
