本文介绍了一种处理 Flowchart 中参数与节点的方法，通过遍历 ActivityBuilder 的属性及 Flowchart 的变量来构建参数字典，并筛选出与当前 FlowNode 相关的父节点。

public override void ShowDialog(PropertyValue propertyValue, IInputElement commandSource)
        {
            ConditionWindow conWnd = new ConditionWindow();
            ModelPropertyEntryToOwnerActivityConverter converter = new ModelPropertyEntryToOwnerActivityConverter();
            ModelItem modelItem = (ModelItem)converter.Convert(propertyValue.ParentProperty, typeof(ModelItem), false, null);
            if (modelItem.Root.GetCurrentValue() is System.Activities.ActivityBuilder)
            {
                var aber = (modelItem.Root.GetCurrentValue() as System.Activities.ActivityBuilder);
                Dictionary<string, Type> parameters = new Dictionary<string, Type>();
                if (aber.Properties != null)
                {
                    foreach (var pro in aber.Properties)
                    {
                        parameters.Add(pro.Name, pro.Type.GetGenericArguments()[0]);
                    }
                }
                if (aber.Implementation is System.Activities.Statements.Flowchart)
                {
                    var fc = aber.Implementation as System.Activities.Statements.Flowchart;
                    if (fc.Variables != null)
                    {
                        foreach (var va in fc.Variables)
                        {
                            parameters.Add(va.Name, va.Type);
                        }
                    }
                    XQSOFT.WF.BLL.Flow bllFlow = new WF.BLL.Flow();
                    var nodes = fc.Nodes.ToList();
                    var parents = bllFlow.GetGoEndByCurrent(nodes, fc.StartNode, modelItem.GetCurrentValue() as System.Activities.Statements.FlowNode);
                    conWnd.Nodes = parents;
                    conWnd.Parameters = parameters;
                }
            }

            if (conWnd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
            {
                propertyValue.Value = conWnd.CurrentActivity;

            }
        }
