我有以下 XML，需要反序列化以获取“ThreadGroup.num_threads”、“ThreadGroup.ramp_time”、“HTTPSampler.path”和“HTTPSampler.domain”的值。 <TestPlan> <hashTree> <hashTree> <ThreadGroup> <stringProp name="ThreadGroup.on_sample_error">continue</stringProp> <stringProp name="ThreadGroup.num_threads">10</stringProp> <stringProp name="ThreadGroup.ramp_time">1</stringProp> <longProp name="ThreadGroup.start_time">1517853259000</longProp> <longProp name="ThreadGroup.end_time">1517853259000</longProp> <boolProp name="ThreadGroup.scheduler">false</boolProp> <stringProp name="ThreadGroup.duration"></stringProp> <stringProp name="ThreadGroup.delay"></stringProp> </ThreadGroup> <hashTree> <hashTree> <HTTPSamplerProxy> </HTTPSamplerProxy> </hashTree> </hashTree> </hashTree> </hashTree> </TestPlan>上面的代码给出了具有许多附加属性值的所需值，并且代码似乎也很长。但是，我需要这 4 个值。请提出任何更好的解决方案。

我已经更新了它以使其易于使用。
我开始之前，我决定，你可能想的可能性longProps在HTTPSamplerProxy部分。它还使编码（很多）更容易和更清洁。我已经在没有任何 longProps 的情况下对其进行了测试，只是为了确保它以您期望的方式与现有 XML 一起工作。
原流程
对原始描述的更新以斜体显示
我所做的是使用标准的 XSD.exe 工具获取您的源 XML 文件（在 HTTPSamplerProxy 部分中有一个额外的 longProp）并创建一个 XSD。然后我再次使用 XSD.exe 创建了一个（非常丑陋的）C# 文件。那时，整个混乱的根源是 TestPlan 类。这是 XSD.exe 生成的内容（更新 - 对新发出的 XSD.exe 代码的唯一更改是顶部的命名空间声明）：

其余的大部分是新的
XSD.exe 发出的代码创建了一组部分类。我在一个单独的源文件中以几种方式扩展了部分类。但是，在开始之前，我声明了一个接口和一个静态工作类。
public interface IGrouping {
boolProp[] boolProp { get; }
stringProp[] stringProp { get; }
longProp[] longProp { get; }
Dictionary<string, bool?> BoolProperties { get; }
Dictionary<string, long?> LongProperties { get; }
Dictionary<string, string> StringProperties { get; }
}
和
public static class PropertyGrouper {
public static void GroupProperties(IGrouping itemToGroup) {
//has this been done before, if yes, return
if (itemToGroup.StringProperties.Count > 0 || itemToGroup.BoolProperties.Count > 0 || itemToGroup.LongProperties.Count > 0 ) {
return;
}
//otherwise
if (itemToGroup.boolProp != null) {
foreach (var bProp in itemToGroup.boolProp) {
var succeeded = bool.TryParse(bProp.Value, out var bValue);
itemToGroup.BoolProperties.Add(bProp.name, succeeded ? bValue : (bool?)null);
}
}
if (itemToGroup.longProp != null) {
foreach (var lProp in itemToGroup.longProp) {
var succeeded = long.TryParse(lProp.Value, out var lValue);
itemToGroup.LongProperties.Add(lProp.name, succeeded ? lValue : (long?)null);
}
}
if (itemToGroup.stringProp != null) {
foreach (var sProp in itemToGroup.stringProp) {
itemToGroup.StringProperties.Add(sProp.name, sProp.Value);
}
}
}
}
有了这些，我扩展了每个 XSD.exe 发出的类。这TestPlan门课很简单——我只是添加了一个类型化的属性：
public partial class TestPlan {
[XmlIgnore]
public hashTree HashTree => Items[0] as hashTree;
}
在hashTreeThreadGroup与hashTreeHTTPSamplerProxy类相同的方式（请记住，我没有点名任何这些类的，XSD.EXE从XML命名他们）进行了扩展。每个都被声明为实现IGrouping接口，并且每个都有 3 个属性字典（根据 的要求IGrouping）。IGrouping接口中的三个数组位于XSD 发出的代码中：
public partial class hashTreeThreadGroup : IGrouping {
[XmlIgnore]
public Dictionary<string, bool?> BoolProperties { get; } = new Dictionary<string, bool?>();
[XmlIgnore]
public Dictionary<string, long?> LongProperties { get; } = new Dictionary<string, long?>();
[XmlIgnore]
public Dictionary<string, string> StringProperties { get; } = new Dictionary<string, string>();
}
public partial class hashTreeHTTPSamplerProxy : IGrouping {
[XmlIgnore]
public Dictionary<string, bool?> BoolProperties { get; } = new Dictionary<string, bool?>();
[XmlIgnore]
public Dictionary<string, long?> LongProperties { get; } = new Dictionary<string, long?>();
[XmlIgnore]
public Dictionary<string, string> StringProperties { get; } = new Dictionary<string, string>();
}
最后，我延长了hashTree课程。我添加了三个类型化的属性，每个都有一个空检查以使事情变得干净。ThreadGroupItem 和 HttpSamplerProxyItem 属性分别调用PropertyGrouper.GroupProperties. 第一次调用时，XmlSerializer 创建的属性数组中的属性被复制到字典中。
public partial class hashTree {
[XmlIgnore]
public hashTree HashTree {
get {
if (hashTree1 != null) {
return hashTree1[0] as hashTree;
} else {
return null;
}
}
}
[XmlIgnore]
public hashTreeThreadGroup ThreadGroupItem {
get {
if (ThreadGroup != null) {
var threadGroup = ThreadGroup[0]; // as hashTreeThreadGroup;
PropertyGrouper.GroupProperties(threadGroup);
return threadGroup;
} else {
return null;
}
}
}
[XmlIgnore]
public hashTreeHTTPSamplerProxy HttpSamplerProxyItem {
get {
if (HTTPSamplerProxy != null) {
var httpSamplerProxy = HTTPSamplerProxy[0];
PropertyGrouper.GroupProperties(httpSamplerProxy);
return httpSamplerProxy;
} else {
return null;
}
}
}
}
一切就绪后，我运行了相同的代码。
TestPlan result;
using (var stream = new FileStream("source.xml", FileMode.Open, FileAccess.Read)) {
var serializer = new XmlSerializer(typeof(TestPlan));
result = (TestPlan)serializer.Deserialize(stream);
}
此代码是我使用第一个示例访问您的数据的方式。
var numThreadsParsed = long.TryParse((((XmlSerializeForm.hashTree)result.Items[0]).hashTree1[0].ThreadGroup[0].stringProp[1].Value), out var numThreads);
var httpSamplerPath = ((XmlSerializeForm.hashTree)result.Items[0]).hashTree1[0].hashTree1[0].hashTree1[0].HTTPSamplerProxy[0].stringProp[4].Value;
但是，通过我做了一些简单的添加（好吧，代码并没有那么复杂，但是做对了），访问属性就更简洁了：
string numThreadsParsed = result.HashTree.HashTree.ThreadGroupItem.StringProperties["ThreadGroup.num_threads"];
long? startTime = result.HashTree.HashTree.ThreadGroupItem.LongProperties["ThreadGroup.start_time"];
string httpSamplerPath = result.HashTree.HashTree.HashTree.HashTree.HttpSamplerProxyItem.StringProperties["HTTPSampler.path"];
bool? useKeepAlive = result.HashTree.HashTree.HashTree.HashTree.HttpSamplerProxyItem.BoolProperties["HTTPSampler.use_keepalive"];
给你！

使用外部 lib Cinchoo ETL - 一个开源库，您可以轻松获取所选节点值，如下所示
定义 .NET 类型
public class TestPlan
{
[ChoXmlNodeRecordField(XPath = @"/ThreadGroup/stringProp[@name=""ThreadGroup.on_sample_error""]")]
public string NumThreads { get; set; }
[ChoXmlNodeRecordField(XPath = @"/ThreadGroup/stringProp[@name=""ThreadGroup.ramp_time""]")]
public int RampTime { get; set; }
[ChoXmlNodeRecordField(XPath = @"/hashTree/hashTree/HTTPSamplerProxy/stringProp[@name=""HTTPSampler.path""]")]
public string Path { get; set; }
[ChoXmlNodeRecordField(XPath = @"/hashTree/hashTree/HTTPSamplerProxy/stringProp[@name=""HTTPSampler.domain""]")]
public string Domain { get; set; }
}
然后使用 Cinchoo ETL 反序列化输入 xml，如下所示
static void Main()
{
using (var p = new ChoXmlReader<TestPlan>("*** XML file path ***")
.WithXPath("/TestPlan/hashTree/hashTree")
)
{
foreach (var rec in p)
Console.WriteLine(rec.Dump());
}
}
输出：
-- ChoXmlReaderTest.Program+TestPlan State --
NumThreads: continue
RampTime: 1
Path: /v1/test/test?debug=false
Domain: www.abc.com/abc-service-api
希望能帮助到你。
