我正在尝试将对象附加到XML文件中。我目前遇到的问题是它将所有内容追加到第一级。我试图将列表作为父元素,并将项目列为子元素。
我尝试了什么:我遇到了一些他们使用循环的帖子,但我无法将其与我的上下文和代码联系起来。
代码:
XDocument xDocument = XDocument.Load(@"C:\Users\hci\Desktop\Nazish\TangramsTool\TangramsTool\patterndata.xml");
XElement root = xDocument.Element("Patterns");
foreach (Pattern currentPattern in PatternDictionary.Values)
{
String filePath = currentPattern.Name.ToString();
IEnumerable<XElement> rows = root.Descendants("Pattern"); // Returns a collection of the descendant elements for this document or element, in document order.
XElement firstRow = rows.First(); // Returns the first element of a sequence.
if (currentPattern.PatternDistancesList.Count() == 9)
{
firstRow.AddBeforeSelf( //Adds the specified content immediately before this node.
new XElement("Pattern"),
new XElement("Name", filePath.Substring(64)),
new XElement("PatternDistancesList"),
new XElement("PatternDistance", currentPattern.PatternDistancesList[0].ToString()),
new XElement("PatternDistance", currentPattern.PatternDistancesList[1].ToString()),
}
}
当前XML文件:
<Pattern/>
<Name>match.jpg</Name>
<PatternDistancesList/>
<PatternDistance>278</PatternDistance>
<PatternDistance>380</PatternDistance>
最终结果我想要什么:
<Pattern>
<Name>match.jpg</Name>
<PatternDistancesList>
<PatternDistance>278</PatternDistance>
<PatternDistance>380</PatternDistance>
</PatternDistancesList>
<Pattern/>
任何提示将不胜感激。我是WPF和C#的新手,所以还在努力学习。
答案 0 :(得分:2)
这应该可以解决问题:
firstRow.AddBeforeSelf(
new XElement("Pattern",
new XElement("Name", filePath.Substring(64)),
new XElement("PatternDistancesList",
new XElement("PatternDistance", currentPattern.PatternDistancesList[0].ToString()),
new XElement("PatternDistance", currentPattern.PatternDistancesList[1].ToString()))));
