如何在C#中从plist(xml)读取键值

我只想获得softwareversionBundleId&的字符串.捆绑版本密钥
我怎样才能将它存储到字典中以便我能够轻松搞定？

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>genre</key>
    <string>Application</string>
    <key>bundLeversion</key>
    <string>2.0.1</string>
    <key>itemName</key>
    <string>AppName</string>
    <key>kind</key>
    <string>software</string>
    <key>playlistName</key>
    <string>AppName</string>
    <key>softwareIconNeedsShine</key>
    <true/>
    <key>softwareversionBundleId</key>
    <string>com.company.appname</string>
</dict>
</plist>

我尝试了以下代码.

XDocument docs = XDocument.Load(newFilePath);
            var elements = docs.Descendants("dict");
            Dictionary<string,string> keyvalues = new Dictionary<string,string>();



            foreach(var a in elements)
            {

               string key= a.Attribute("key").Value.ToString();
               string value=a.Attribute("string").Value.ToString();
                keyvalues.Add(key,value); 
            }

它抛出对象引用异常.

解决方法

<键>以及< string>或< true />不是属性,它们是< dict>的子元素.通过接近配对.要构建字典,您需要将它们压缩在一起,如下所示：

var keyvalues = docs.Descendants("dict")
            .SelectMany(d => d.Elements("key").Zip(d.Elements().Where(e => e.Name != "key"),(k,v) => new { Key = k,Value = v }))
            .ToDictionary(i => i.Key.Value,i => i.Value.Value);

结果是一个字典包含：

06001
