我不明白为什么我的代码不起作用。我不希望xml文件按精确顺序排列。换句话说，我想治疗：

  <File>
    <Signature>4D5A</Signature>
    <Extension>EXE|COM|DLL|SYS</Extension>
    <Description>WindowsExecutable</Description>
  </File>


4D5A
EXE | COM | DLL | SYS
窗口可执行文件

就像：

 <File>
    <Description>WindowsExecutable</Description>        
    <Extension>EXE|COM|DLL|SYS</Extension>
    <Signature>4D5A</Signature>
  </File>


窗口可执行文件
EXE | COM | DLL | SYS
4D5A

我解析该xml文件的代码是：

类文件签名
{
公共字符串签名；
公共字符串[]扩展名；
公共字符串说明{get；set；}
}
//这里的构造函数是我开始实现算法的地方
类文件签名
{
公共静态列表文件；
公共文件签名（）
{
//列出放置文件的位置
文件=新列表（）；
//这就是xml所在的路径
XmlTextReader=新的XmlTextReader（@“A:\Users\Tono\Desktop\SaveContentFromCache\SaveContentFromCache\FileSignatures.xml”）；
while（reader.Read（））
{
//如果我们找到一个file元素，那么
if（reader.Name.ToString（）.ToLower（）.Equals（“文件”））
{
//将整个xml放在一个字符串中
string temp=reader.ReadInnerXml（）.ToString（）；
//创建一个XmlReader
XmlReader-ReaderOffparent=XmlReader.Create（新建StringReader（临时））；
FileSignature f=新文件签名（）；
while（readerOfParent.Read（））/！！！！！！！！！！！！！！！！！！！这就是我得到错误的地方
{
if（readerOfParent.Name.ToString（）.ToLower（）包含（“签名”））
f、 signature=ReaderOffparent.ReadInnerXml（）.ToString（）；
if（readerOfParent.Name.ToString（）.ToLower（）包含（“扩展”））
f、 extensions=readerOfParent.ReadInnerXml（）.ToString（）.Split（“|”）；
if（readerOfParent.Name.ToString（）.ToLower（）.Contains（“description”））
f、 description=readerOfParent.ReadInnerXml（）.ToString（）；
}
添加（f）；
readerOfParent.Close（）；
}
}
}
}

编辑阅读我的算法可能会让人困惑。我只需要将xml文件中的内容放入c#

XDocument xdoc=XDocument.Load（@“A:\Users\Tono\Desktop\SaveContentFromCache\SaveContentFromCache\FileSignatures.xml”）；
列表文件签名=（来自xdoc.Element（“文件”）.Elements（“文件”）中的文件）
选择新文件签名
{
签名=file.Element（“签名”）.Value，
扩展名=file.Element（“扩展名”）.Value.Split（“|”），
description=file.Element（“description”）.Value
}).ToList（）；

在等待答案的同时，我正在寻找解决方案。我想我应该再试试。不管怎样，我得出的结论如下：

// list where to place the files
Files = new List<FileSignature>();

//Load xml
XDocument xdoc = XDocument.Load(@"A:\Users\Tono\Desktop\SaveContentFromCache\SaveContentFromCache\FileSignatures.xml");

//Run query
var files = from elements in xdoc.Descendants("File")
           select new { 
               Children = elements.Descendants()
           };

//Loop through results
foreach (var elem in files)
{
    FileSignature f = new FileSignature();
    foreach (var lv2 in elem.Children)
    {
        if (lv2.Name.ToString().ToUpper().Contains("SIGNATURE"))
            f.signature = lv2.Value.ToString();
        else if (lv2.Name.ToString().ToUpper().Contains("DESCRIPTION"))
            f.description = lv2.Value.ToString();
        else if (lv2.Name.ToString().ToUpper().Contains("EXTENSION"))
            f.extensions = lv2.Value.ToString().Split('|');              
    }
    Files.Add(f);
}

//列出放置文件的位置
文件=新列表（）；
//加载xml
XDocument xdoc=XDocument.Load（@“A:\Users\Tono\Desktop\SaveContentFromCache\SaveContentFromCache\FileSignatures.xml”）；
//运行查询
var files=来自xdoc.subjects（“文件”）中的元素
选择新{
子元素=元素。子元素（）
};
//循环浏览结果
foreach（文件中的变量元素）
{
FileSignature f=新文件签名（）；
foreach（元素子元素中的变量lv2）
{
if（lv2.Name.ToString（）.ToUpper（）包含（“签名”））
f、 signature=lv2.Value.ToString（）；
else if（lv2.Name.ToString（）.ToUpper（）.Contains（“DESCRIPTION”））
f、 description=lv2.Value.ToString（）；
else if（lv2.Name.ToString（）.ToUpper（）包含（“扩展”））
f、 extensions=lv2.Value.ToString（）.Split（“|”）；
}
添加（f）；
}

编辑未处理的执行解决方案看起来更简单
