C# 从uiTypeEditor获取/设置工作流变量

我已经创建了一个自定义ui编辑器来处理工作流变量值的设置。我想做的是能够在uieditor中获取为工作流设置的任何变量的值

public class MyCustomEditor : UITypeEditor
{
   public override object EditValue(ITypeDescriptorContext context, IServiceProvider provider, object value){

       IWindowsFormsEditorService service = (IWindowsFormsEditorService)provider.GetService(typeof(IWindowsFormsEditorService));

       IBuildDefinition buildDefinition = (IBuildDefinition)provider.GetService(typeof(IBuildDefinition));

       // Variable set in the workflow metadata to use this ui editor
       MyCustomVariable variable = value as MyCustomVariable;

       // Tried getting it from the Process Parameters but the only thing in there was BuildSettings
       var processParms = WorkflowHelpers.DeserializeProcessParameters(buildDefinition.ProcessParameters);

       object obj;
       processParms.TryGetValue("BuildSettings", out obj);
       BuildSettings buildSettings = obj as BuildSettings;

       // I want to be able to access other variable for the workflow, everything above works. But MyCustomVariable is set in the Metadata to use this editor. I want to get the value of another variable in the workflow as well

      return variable;
   }
}

我错了，当我查看ProcessParameters时，构建定义还没有保存，所以这就是为什么我只看到“BuildSettings”，一旦我在保存的构建定义上反序列化它们，我就可以看到所有变量

var processParms = WorkflowHelpers.DeserializeProcessParameters(buildDefinition.ProcessParameters);

object obj;
processParms.TryGetValue("MyOtherVariable", out obj);
MyOtherVariable myOtherVariable = obj as MyOtherVariable;

您是否尝试过使用BuildDefinition.Process.Parameters？IIRC该参数与BuildDefinition.ProcessParameters之间有细微的区别，后者仅在定义本身上重写。编辑BuildRequest时也可能显示编辑器。您还必须检查此处定义的流程参数。我刚刚尝试反序列化WorkflowHelpers.DeserializeProcessParametersBuildDefinition.process.parameters，但在类型上找不到匹配的构造函数，因此出现了一个错误。在尝试使用以下代码时，您可以使用参数或FactoryMethod指令来构造类型。@mikez我正确地看到了xml值，只需要知道如何获取当前值？好的，我必须弄清楚流程模板中是否定义了参数/变量，以便覆盖默认值。我只是使用XDocument来解析BuildDefinition.Process.Parameters并查找特定元素的存在性。也许您可以做类似的事情，如果参数值是一个基本类型，这可能很容易，但是如果它是一个自定义类型，这可能很困难。
