c# - TFS 2010 : Why is it not possible to deserialize a Dictionary with XamlWriter.Save 当我可以使用 XamlReader 进行反序列化时

Question

public static string GetXml(Dictionary<string, object> parameters)
{
    return XamlWriter.Save(parameters);
}

上述语句返回一个NotSupportedException。

奇怪的是我可以使用XamlReader 来序列化字典。

public static Dictionary<string, object> GetParameters(IBuildDetail buildDetail, string buildDefinition)
{
    var tfsProject = buildDetail.BuildDefinition.TeamProject;
    var buildServer = buildDetail.BuildServer;
    var buildDef = buildServer.GetBuildDefinition(tfsProject, buildDefinition);
    using (var stringReader = new StringReader(buildDef.ProcessParameters))
    {
        using (var xmlTextReader = new XmlTextReader(stringReader))
        {
            return (Dictionary<string, object>) XamlReader.Load(xmlTextReader);
        }
    }
}

我用了JetBrains dotPeek了解 Microsoft 如何序列化和反序列化 Dictionary<string, object>适用于 TFS 2010 工作流。

他们使用反序列化: Microsoft.TeamFoundation.Build.Workflow.WorkflowHelpers.DeserializeProcessParameters(string parameterValues)

他们使用序列化: WorkflowHelpers.SerializeProcessParameters(IDictionary<string, object> parameterValues)

程序集:Microsoft.TeamFoundation.Build.Workflow.dll

我最初的问题是我试图添加 IBuildRequest.ProcessParameters排队构建之前的值。

private static void SetProcessParametersForSubBuild(IBuildRequest buildRequest, Dictionary<string, object> processParametersForSubBuild, IBuildDefinition buildDefinition)
{
    var subBuildProcessParameters = WorkflowHelpers.DeserializeProcessParameters(buildDefinition.ProcessParameters);

    if (processParametersForSubBuild.Any())
    {
        foreach (var processParameter in processParametersForSubBuild)
        {
            if (subBuildProcessParameters.ContainsKey(processParameter.Key))
            {
                subBuildProcessParameters[processParameter.Key] = processParameter.Value;
            }
            else
            {
                subBuildProcessParameters.Add(processParameter.Key, processParameter.Value);
            }
        }
        buildRequest.ProcessParameters = WorkflowHelpers.SerializeProcessParameters(subBuildProcessParameters);
    }
}

队列构建:

var queuedBuild = buildServer.QueueBuild(buildRequest);
