從uiTypeEditor獲取/設置工作流變量

Question

我創建了一個自定義ui編輯器來處理為我的工作流設置變量的值。 我想做的就是能夠獲取uieditor中為工作流設置的任何變量的值。

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;
   }
}

我錯了，當我查看ProcessParameters時，尚未保存構建定義，因此這就是為什么我只看到“ BuildSettings”的原因。一旦在保存的BuildDefinition上反序列化它們，便可以看到所有變量。

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

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