使用 C# 为 XmlSerializer 初始化 XML 成员

Question

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。

Answer 1

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）：/// <remarks/>[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.33440")][System.SerializableAttribute()][System.Diagnostics.DebuggerStepThroughAttribute()][System.ComponentModel.DesignerCategoryAttribute("code")][System.Xml.Serialization.XmlTypeAttribute(AnonymousType = true)][System.Xml.Serialization.XmlRootAttribute(Namespace = "", IsNullable = false)]public partial class hashTree {&nbsp;

&nbsp; &nbsp; &nbsp; &nbsp; this.itemsField = value;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }}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 {&nbsp; &nbsp; boolProp[] boolProp { get; }&nbsp; &nbsp; stringProp[] stringProp { get; }&nbsp; &nbsp; longProp[] longProp { get; }&nbsp; &nbsp; Dictionary<string, bool?> BoolProperties { get; }&nbsp; &nbsp; Dictionary<string, long?> LongProperties { get; }&nbsp; &nbsp; Dictionary<string, string> StringProperties { get; }}和public static class PropertyGrouper&nbsp; {&nbsp; &nbsp; public static void GroupProperties(IGrouping itemToGroup) {&nbsp; &nbsp; &nbsp; &nbsp; //has this been done before, if yes, return&nbsp; &nbsp; &nbsp; &nbsp; if (itemToGroup.StringProperties.Count > 0 || itemToGroup.BoolProperties.Count > 0 || itemToGroup.LongProperties.Count > 0 ) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return;&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; //otherwise&nbsp; &nbsp; &nbsp; &nbsp; if (itemToGroup.boolProp != null) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; foreach (var bProp in itemToGroup.boolProp) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; var succeeded = bool.TryParse(bProp.Value, out var bValue);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; itemToGroup.BoolProperties.Add(bProp.name, succeeded ? bValue : (bool?)null);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; if (itemToGroup.longProp != null) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; foreach (var lProp in itemToGroup.longProp) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; var succeeded = long.TryParse(lProp.Value, out var lValue);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; itemToGroup.LongProperties.Add(lProp.name, succeeded ? lValue : (long?)null);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; if (itemToGroup.stringProp != null) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; foreach (var sProp in itemToGroup.stringProp) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; itemToGroup.StringProperties.Add(sProp.name, sProp.Value);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }}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 {&nbsp; &nbsp; [XmlIgnore]&nbsp; &nbsp; 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 {&nbsp; &nbsp; [XmlIgnore]&nbsp; &nbsp; public Dictionary<string, bool?> BoolProperties { get; } = new Dictionary<string, bool?>();&nbsp; &nbsp; [XmlIgnore]&nbsp; &nbsp; public Dictionary<string, long?> LongProperties { get; } = new Dictionary<string, long?>();&nbsp; &nbsp; [XmlIgnore]&nbsp; &nbsp; public Dictionary<string, string> StringProperties { get; } = new Dictionary<string, string>();}public partial class hashTreeHTTPSamplerProxy : IGrouping {&nbsp; &nbsp; [XmlIgnore]&nbsp; &nbsp; public Dictionary<string, bool?> BoolProperties { get; } = new Dictionary<string, bool?>();&nbsp; &nbsp; [XmlIgnore]&nbsp; &nbsp; public Dictionary<string, long?> LongProperties { get; } = new Dictionary<string, long?>();&nbsp; &nbsp; [XmlIgnore]&nbsp; &nbsp; 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 {&nbsp; &nbsp; [XmlIgnore]&nbsp; &nbsp; public hashTree HashTree {&nbsp; &nbsp; &nbsp; &nbsp; get {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (hashTree1 != null) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return hashTree1[0] as hashTree;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return null;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; [XmlIgnore]&nbsp; &nbsp; public hashTreeThreadGroup ThreadGroupItem {&nbsp; &nbsp; &nbsp; &nbsp; get {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (ThreadGroup != null) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; var threadGroup = ThreadGroup[0]; // as hashTreeThreadGroup;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; PropertyGrouper.GroupProperties(threadGroup);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return threadGroup;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return null;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }&nbsp; &nbsp; [XmlIgnore]&nbsp; &nbsp; public hashTreeHTTPSamplerProxy HttpSamplerProxyItem {&nbsp; &nbsp; &nbsp; &nbsp; get {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (HTTPSamplerProxy != null) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; var httpSamplerProxy = HTTPSamplerProxy[0];&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; PropertyGrouper.GroupProperties(httpSamplerProxy);&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return httpSamplerProxy;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; } else {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return null;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; }}一切就绪后，我运行了相同的代码。&nbsp; &nbsp;TestPlan result;&nbsp; &nbsp;using (var stream = new FileStream("source.xml", FileMode.Open, FileAccess.Read)) {&nbsp; &nbsp; &nbsp; &nbsp;var serializer = new XmlSerializer(typeof(TestPlan));&nbsp; &nbsp; &nbsp; &nbsp;result = (TestPlan)serializer.Deserialize(stream);&nbsp; &nbsp;}此代码是我使用第一个示例访问您的数据的方式。&nbsp;var numThreadsParsed = long.TryParse((((XmlSerializeForm.hashTree)result.Items[0]).hashTree1[0].ThreadGroup[0].stringProp[1].Value), out var numThreads);&nbsp;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：&nbsp;string numThreadsParsed = result.HashTree.HashTree.ThreadGroupItem.StringProperties["ThreadGroup.num_threads"];&nbsp;long? startTime = result.HashTree.HashTree.ThreadGroupItem.LongProperties["ThreadGroup.start_time"];&nbsp;string httpSamplerPath = result.HashTree.HashTree.HashTree.HashTree.HttpSamplerProxyItem.StringProperties["HTTPSampler.path"];&nbsp;bool? useKeepAlive = result.HashTree.HashTree.HashTree.HashTree.HttpSamplerProxyItem.BoolProperties["HTTPSampler.use_keepalive"];给你！
