WPF TreeView：如何从不同模型创建头和节点

我正在进行一个wpf项目，在这个项目中，我必须递归地构建树节点。我想做的是为另一个模型中的节点分配头，例如：

    Request Header  --> node1
                -->node1.1
                -->node1.2
    Response Header  -->node2 
                -->node2.1
                -->node2.2

// building tree 
   public List<TreeModel> BuildTree(IEnumerable<string> strings)
      {
        return (
          from s in strings
          let split = s.Split('.')
          group s by s.Split('.')[0] into g
          select new TreeModel
          {
              Value = g.Key,
              Children = BuildTree(
                from s in g
                where s.Length > g.Key.Length + 1
                select s.Substring(g.Key.Length + 1))
          }
          ).ToList();


    }

 // Here I am creating static MessageElementModel  objects  

                <HierarchicalDataTemplate DataType="{x:Type local:TreeViewModel}" ItemsSource="{Binding Children}">
                    <CheckBox IsChecked="{Binding Value}" Content="{Binding Value}" />
                </HierarchicalDataTemplate>
            </TreeView.Resources>

        </TreeView>



    How can I add header from another model? for this case transactionTypeWSRequestXmlType,transactionTypeWSResponseXmlType and transactionTypeWSRequestXmlType,transactionTypeWSResponseXmlType to the treeview for the nodes I am creating in the TreeNode.BuildTree(request) recursively? 


             and the same for var response;
        var treeNode = new ObservableCollection<TransactionTypeViewModel>() { request,   response };
        }
        return treeNode;
       }
 In the messageElementViewModel I am getting the constructed      nods(TreeNodeModel)+roots(TransactionTypeViewModel)

 here I addded Id so that when I chose any transaction from my Transaction combobox the    tree will display only matching Ids

   public List<MessageElementViewModel> GetAllTreeNodesList()
    {
        messageElements = TransactionType.getAllTreeNodes().Select(msgElements => new      MessageElementViewModel
        {
            Id = msgElements.Id,
            Request = msgElements.Request,
            Response = msgElements.Response,

        }).ToList();

        return messageElements;
    }       
//make it observable 

  public ObservableCollection<MessageElementViewModel> GetAllTreeNodes()
    {
        observableMessageElement = new ObservableCollection<MessageElementViewModel>  (messageElements);
        return observableMessageElement;

    }

 //xaml binding to MessageElementViewModel where I have the roots and nodes combination

  How can I bind all these together in the xaml?

请求头-->节点1
-->节点1.1
-->节点1.2
响应头-->节点2
-->节点2.1
-->节点2.2
//建树

}
//这里我创建的是静态MessageElementModel对象

我之所以要创建这些对象，是因为我想将它们与另一个控件（combobox）关联，以便在选择事件时创建，但这不是我的问题的一部分

      public List<MessageElementModel> GetAllMessageElements()
       {
        string[] request = { "NetworkControl.AlternateIndexText.Value" };
        string[] request2 = { "NetworkControl.NetworkControl.AddressData.TransactionOriginatorID.Value" };
        string[] request3 = { "VehicleSummary.VehicleIdentification.IdentificationID.Value" };

       transactionTypeWSRequestXmlType = TransactionTypeModle.TransactionTypeWSRequestXmlType;
        transactionTypeWSResponseXmlType = TransactionTypeModel.TransactionTypeWSRequestXmlType;


        messageElements.Add(new MessageElementModel(1, transactionTypeWSRequestXmlType,transactionTypeWSResponseXmlType, TreeNode.BuildTree(request)));
        messageElements.Add(new MessageElementModel(1, transactionTypeWSRequestXmlType,transactionTypeWSResponseXmlType, TreeNode.BuildTree(request2)));


        return messageElements;

    }

    The transactionTypeWSRequestXmlType,transactionTypeWSResponseXmlType and transactionTypeWSRequestXmlType,transactionTypeWSResponseXmlType are the headers of the tree (TreeNode.BuildTree(request))

                <HierarchicalDataTemplate DataType="{x:Type local:TreeViewModel}" ItemsSource="{Binding Children}">
                    <CheckBox IsChecked="{Binding Value}" Content="{Binding Value}" />
                </HierarchicalDataTemplate>

        var treeNode = new ObservableCollection<TransactionTypeViewModel>() { request,   response };
        }
        return treeNode;
       }

            Id = msgElements.Id,
            Request = msgElements.Request,
            Response = msgElements.Response,

        }).ToList();

    }

如何从其他模型添加标题？对于这种情况，是否将transactionTypeWSRequestXmlType、transactionTypeWSResponseXmlType和transactionTypeWSRequestXmlType、transactionTypeWSResponseXmlType递归地添加到我在TreeNode.BuildTree（请求）中创建的节点的树视图？
var响应也是如此；
var treeNode=新的observeCollection（）{request，response}；
}
返回树节点；
}
在messageElementViewModel中，我得到构造的节点（TreeNodeModel）+根（TransactionTypeViewModel）
在这里我添加了Id，这样当我从我的事务组合框中选择任何事务时，树将只显示匹配的Id
公共列表getAllTreeNodeList（）
{
messageElements=TransactionType.getAllTreeNodes（）.Select（msgElements=>new MessageElementViewModel
{
Id=msgElements.Id，
Request=msgElements.Request，
响应=msgElements.Response，
}).ToList（）；
返回消息元素；
}       
//使其可见
公共可观测集合GetAllTreeNodes（）
{
observableMessageElement=新的ObservableCollection（messageElements）；
返回可观察的消息元素；
}
//xaml绑定到MessageElementViewModel，其中我有根和节点组合
如何将所有这些绑定到xaml中？

创建视图绑定到的单个ViewModel，然后使用此ViewModel“包装”模型。HighCore您能告诉我更多详细信息吗？例如，如果您想区分不同类型的节点，最简单的方法是为每种类型的节点提供不同的类型，然后为每种节点类型创建不同的数据模板。你指的是我所说的请求和响应根吗？我能在代码示例中看到它吗？我找到了一种解决方法，我将很快发布解决方案
