Question

我一直试图理解这几个小时但没有运气。我有一个基于班级的列表：

public class xmldata //Class to receive items list
{
    public string xml_filename { get; set; }
    public string colorname { get; set; }
    public string colorvalues { get; set; }

}

然后我创建了一个单独的类来保存列表：

public class xmldatalist
{
    public List<xmldata> FullList = new List<xmldata>();
}

此列表的每个位置（FullList）包含xmldata中的三个元素 - 我想要关注的特定元素是xml_filename。

我的问题是：如何使用foreach循环迭代此列表，并为每个xml_filename值生成一个XML文件。

即：从位置0到5，xml_filename是file1.bla 从位置6到9，xml_filename是file2.bla

我想要一个将通过位置0到5迭代的foreach，检查xml_filename是否为file1.bla并写入位置0到5的属性。

类似：

检查xml_filename 创建文件写属性如果xml_filename在下一个位置是相同的继续写这个文件如果下一个位置的xml_file不同，请写入新文件

现在我正试图通过这样做来使用Linq：

foreach (var ListXmlFileName in XMLList.FullList.Where(x => x.xml_filename == XmlFilename))
{
}

但是我对如何继续有点失落。我尝试的另一种方法是：

foreach (xmldata XmlStuff in XmlItems.ItemsList)
{
}

也没有成功。编写XML的代码是：

public void writexml(xmldatalist XmlItems, variables GlobalVars)
{
    XmlWriterSettings settings = new XmlWriterSettings
    {
        Indent = true,
        IndentChars = "\t",
        NewLineChars = Environment.NewLine,
        NewLineHandling = NewLineHandling.Replace,
        Encoding = new UTF8Encoding(false)
    };
    int pos = 0;



    foreach (xmldata XmlStuff in XmlItems.ItemsList)
    {

        string DesktopFolder = Environment.GetFolderPath(Environment.SpecialFolder.DesktopDirectory);
        string XmlFilename = "dadada";
        string FileExtension = ".xml";
        string PathString = Path.Combine(DesktopFolder, "XML");
        System.IO.Directory.CreateDirectory(PathString);
        string FullPath = Path.Combine(PathString, XmlFilename + FileExtension);

        XmlWriter XmlWriting = XmlWriter.Create(FullPath, settings);

            XmlWriting.WriteStartDocument();
            XmlWriting.WriteStartElement("JMF");
            XmlWriting.WriteAttributeString("SenderID", "InkZone-Controller");
            XmlWriting.WriteAttributeString("Version", "1.2");
            //XmlWriting.WriteAttributeString("xmlns","",null, "http://www.CIP4.org/JDFSchema_1_1");

            XmlWriting.WriteStartElement("Command");
            XmlWriting.WriteAttributeString("ID", "cmd.00695");
            XmlWriting.WriteAttributeString("Type", "Resource");


            XmlWriting.WriteStartElement("ResourceCMDParams");
            XmlWriting.WriteAttributeString("ResourceName", "InkZoneProfile");
            XmlWriting.WriteAttributeString("JobID", "K_41");


            XmlWriting.WriteStartElement("InkZoneProfile");
            XmlWriting.WriteAttributeString("ID", "r0013");
            XmlWriting.WriteAttributeString("Class", "Parameter");
            XmlWriting.WriteAttributeString("Locked", "false");
            XmlWriting.WriteAttributeString("Status", "Available");
            XmlWriting.WriteAttributeString("PartIDKeys", "SignatureName SheetName Side Separation");
            XmlWriting.WriteAttributeString("DescriptiveName", "Schieberwerte von DI");
            XmlWriting.WriteAttributeString("ZoneWidth", "32");


            XmlWriting.WriteStartElement("InkZoneProfile");
            XmlWriting.WriteAttributeString("SignatureName", "SIG1");

            XmlWriting.WriteStartElement("InkZoneProfile");
            XmlWriting.WriteAttributeString("Locked", "False");
            XmlWriting.WriteAttributeString("SheetName", "S1");

            XmlWriting.WriteStartElement("InkZoneProfile");
            XmlWriting.WriteAttributeString("Side", "Front");

我也试过这个但是没有按预期工作（while循环）

       while(XmlStuff.xml_filename == XmlItems.ItemsList[pos].xml_filename)
        {
            XmlWriting.WriteStartElement("InkZoneProfile");
            XmlWriting.WriteAttributeString("Separation", XmlItems.ItemsList[pos].colorname);
            XmlWriting.WriteAttributeString("ZoneSettingsX", XmlItems.ItemsList[pos].colorvalues);
            XmlWriting.WriteEndElement();
            pos++;
        }
    XmlWriting.WriteEndDocument();
    XmlWriting.Close();     
    }
}

任何帮助都将受到高度赞赏。非常感谢。

这会更准确：

<InkZoneProfile Separation="Cyan" ZoneSettingsX="0.391 0.36 0.097 0.058 0 0 0 0 0 0 0 0 0.178 0.394 0.201 0.088"/>

假设这属于file1。 File1将有五个 SomeColor和SomeValues位于列表的每个位置。

Answer 1

这就是你想要的：

[Serializable]
[XmlType("InkZoneProfile")]
public class xmldata //Class to receive items list
{
    [XmlIgnore]
    public string xml_filename { get; set; }

    [XmlAttribute("Separation")]
    public string colorname { get; set; }

    [XmlAttribute("ZoneSettingsX")]
    public string colorvalues { get; set; }

}

FullList.Add(new xmldata { xml_filename = @"D:\File_One", colorname = "Red", colorvalues = "#FF0000" });
FullList.Add(new xmldata { xml_filename = @"D:\File_One", colorname = "Blue", colorvalues = "#0000FF" });
FullList.Add(new xmldata { xml_filename = @"D:\File_Two", colorname = "Black", colorvalues = "#000000" });
FullList.Add(new xmldata { xml_filename = @"D:\File_Two", colorname = "White", colorvalues = "#FFFFFF" });

Dictionary<string, List<xmldata>> xmlFiles = new Dictionary<string, List<xmldata>>();
foreach (var item in FullList)
{
    if (!xmlFiles.ContainsKey(item.xml_filename)) xmlFiles[item.xml_filename] = new List<xmldata>();
    xmlFiles[item.xml_filename].Add(item);
}

foreach (var i in xmlFiles)
{
    string yourXMLFileName = i.Key;
    List<xmldata> xmlDataOfThisFile = i.Value;
    Console.WriteLine(yourXMLFileName);
    try
    {
        using (FileStream fs = new FileStream(yourXMLFileName, FileMode.Create, FileAccess.Write, FileShare.None))
        {
            XmlSerializer serializer = new XmlSerializer(typeof(List<xmldata>));
            serializer.Serialize(fs, FullList);
        }
    }
    catch(Exception ex)
    {
        Console.WriteLine(ex.Message);
        Console.WriteLine(ex.InnerException);
    }
}

这将创建此XML：

<?xml version="1.0"?>
<ArrayOfInkZoneProfile xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
  <InkZoneProfile Separation="Red" ZoneSettingsX="#FF0000" />
  <InkZoneProfile Separation="Blue" ZoneSettingsX="#0000FF" />
  <InkZoneProfile Separation="Black" ZoneSettingsX="#000000" />
  <InkZoneProfile Separation="White" ZoneSettingsX="#FFFFFF" />
</ArrayOfInkZoneProfile>
