TestRunType的序列化抛出异常[重复]

Question

我正在尝试分析一些 trx 文件 (webTestResults) 以输出合成 excel 文件。

首先，我使用 trx xsd 架构（Visual Studio 目录中的 vstst.xsd）生成一堆 C# 类。

然后，我尝试根据 TestRunType 的类型（从架构生成）实例化 XmlSerializer。

XmlSerializer xmlSer = new XmlSerializer(typeof(TestRunType));

XMLSerializer 实例化引发异常：

System.InvalidOperationException: There was an error reflecting type 'TestRunType'. ---> System.InvalidOperationException: There was an error reflecting property 'Items'. ---> System.InvalidOperationException: There was an error reflecting type 'TestRunTypeTestDefinitions'. ---> System.InvalidOperationException: There was an error reflecting property 'Items'. ---> System.InvalidOperationException: There was an error reflecting type 'OrderedTestType'. ---> System.InvalidOperationException: There was an error reflecting type 'CodedWebTestElementType'. ---> System.InvalidOperationException: There was an error reflecting property 'Items'. ---> System.InvalidOperationException: Member 'CodedWebTestElementType.Items' hides inherited member 'BaseTestType.Items', but has different custom attributes.

   at System.Xml.Serialization.XmlReflectionImporter.InitializeStructMembers(StructMapping mapping, StructModel model, Boolean openModel, String typeName, RecursionLimiter limiter)

什么是自定义属性？ 只是 BaseTestType 的开始：

public abstract partial class BaseTestType {

    private object[] itemsField;

    private bool enabledField;

    private string idField;

    private string nameField;

    private bool isGroupableField;

    private int priorityField;

    private string namedCategoryField;

    private string storageField;

    public BaseTestType() {
        this.enabledField = true;
        this.isGroupableField = true;
        this.priorityField = 2147483647;
        this.namedCategoryField = "";
    }

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("Agent", typeof(BaseTestTypeAgent))]
    [System.Xml.Serialization.XmlElementAttribute("Css", typeof(BaseTestTypeCss))]
    [System.Xml.Serialization.XmlElementAttribute("DeploymentItems", typeof(BaseTestTypeDeploymentItems))]
    [System.Xml.Serialization.XmlElementAttribute("Description", typeof(object))]
    [System.Xml.Serialization.XmlElementAttribute("Execution", typeof(BaseTestTypeExecution))]
    [System.Xml.Serialization.XmlElementAttribute("Owners", typeof(BaseTestTypeOwners))]
    [System.Xml.Serialization.XmlElementAttribute("Properties", typeof(BaseTestTypeProperties))]
    [System.Xml.Serialization.XmlElementAttribute("TcmInformation", typeof(TcmInformationType))]
    [System.Xml.Serialization.XmlElementAttribute("TestCategory", typeof(BaseTestTypeTestCategory))]
    [System.Xml.Serialization.XmlElementAttribute("WorkItemIDs", typeof(WorkItemIDsType))]
    public object[] Items {
        get {
            return this.itemsField;
        }
        set {
            this.itemsField = value;
        }
    }

和 CodedWebTestElementType ：

/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.1")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://microsoft.com/schemas/VisualStudio/TeamTest/2010")]
public partial class CodedWebTestElementType : BaseTestType {

    private object[] itemsField;

    /// <remarks/>
    [System.Xml.Serialization.XmlElementAttribute("IncludedWebTests", typeof(CodedWebTestElementTypeIncludedWebTests))]
    [System.Xml.Serialization.XmlElementAttribute("WebTestClass", typeof(CodedWebTestElementTypeWebTestClass))]
    public object[] Items {
        get {
            return this.itemsField;
        }
        set {
            this.itemsField = value;
        }
    }
}

有人可以向我解释一下问题是什么吗？

谢谢...

Answer 1

解决方案是从派生类（CodedWebTestElementType 和 GenericTestType）中删除 Items 属性，但也将序列化属性移动到基类，以免在您有编码的 Web 测试时丢失值或通用测试。

IOW，解决方法如下。

首先，从CodedWebTestElementType 类型中删除Items 属性

/// <remarks/>
[System.CodeDom.Compiler.GeneratedCodeAttribute("xsd", "4.0.30319.1")]
[System.SerializableAttribute()]
[System.Diagnostics.DebuggerStepThroughAttribute()]
[System.ComponentModel.DesignerCategoryAttribute("code")]
[System.Xml.Serialization.XmlTypeAttribute(Namespace="http://microsoft.com/schemas/VisualStudio/TeamTest/2010")]
public partial class CodedWebTestElementType : BaseTestType {
}

然后，将它的两个XmlElementAttribute 属性移动到BaseTestType 基类（参见最后两个）：

/// <remarks/>
[System.Xml.Serialization.XmlElementAttribute("Agent", typeof(BaseTestTypeAgent))]
[System.Xml.Serialization.XmlElementAttribute("Css", typeof(BaseTestTypeCss))]
[System.Xml.Serialization.XmlElementAttribute("DeploymentItems", typeof(BaseTestTypeDeploymentItems))]
[System.Xml.Serialization.XmlElementAttribute("Description", typeof(object))]
[System.Xml.Serialization.XmlElementAttribute("Execution", typeof(BaseTestTypeExecution))]
[System.Xml.Serialization.XmlElementAttribute("Owners", typeof(BaseTestTypeOwners))]
[System.Xml.Serialization.XmlElementAttribute("Properties", typeof(BaseTestTypeProperties))]
[System.Xml.Serialization.XmlElementAttribute("TcmInformation", typeof(TcmInformationType))]
[System.Xml.Serialization.XmlElementAttribute("TestCategory", typeof(BaseTestTypeTestCategory))]
[System.Xml.Serialization.XmlElementAttribute("WorkItemIDs", typeof(WorkItemIDsType))]
[System.Xml.Serialization.XmlElementAttribute("IncludedWebTests", typeof(CodedWebTestElementTypeIncludedWebTests))]
[System.Xml.Serialization.XmlElementAttribute("WebTestClass", typeof(CodedWebTestElementTypeWebTestClass))]
public object[] Items
{
    get {
        return this.itemsField;
    }
    set {
        this.itemsField = value;
    }
}

之后，对 GenericTestType 类执行相同的操作。

这样您在获得 IncludedWebTests、WebTestClass、Command 或 SummaryXmlFile 时不会丢失信息一天的节点。
