從程序集動態生成WinForms TreeView

Question

我幾乎已經掌握了它，但我很難優雅地完成最後一部分。這個答案是根據Jeremy Thompson提交的答案進行更新的。這是我到目前爲止：

public void SetupTree() 
{ 
    var types = Assembly.Load("Data").GetTypes().Where(t => t.IsPublic && t.IsClass); 

    if (types.Count() > 0) 
    { 
     if (treeView_left.Nodes.Count == 0) 
     { 
      treeView_left.Nodes.Add(new TreeNode("Structure Data")); 
      treeView_left.Nodes[0].Nodes.Add(types.First().GetHashCode().ToString(), types.First().Name); 
     } 

     foreach (Type type in types) 
     { 
      BuildTree(types, type, treeView_left.Nodes[0].Nodes[0]); 
     } 
    } 

    treeView_left.Refresh(); 
} 

private void BuildTree(IEnumerable<Type> types, Type type, TreeNode parentNode) 
{ 
    var tempNodes = treeView_left.Nodes.Find(type.BaseType.GetHashCode().ToString(), true); 
    if (tempNodes.Count() > 0) 
    { 
     parentNode = tempNodes[0]; 
     if (tempNodes.Count() != 1) 
     { 
      //TODO: warning 
     } 
    } 

    if (parentNode != null) 
    { 
     if (treeView_left.Nodes.Find(type.GetHashCode().ToString(), true).Count() == 0) 
     { 
      parentNode.Nodes.Add(type.GetHashCode().ToString(), type.Name); 
     } 

     foreach (Type t in types.Where(x => x.IsSubclassOf(type))) 
     { 
      BuildTree(types, t, parentNode.Nodes[type.GetHashCode().ToString()]); 
     } 
    } 
} 

這產生了我期待的結果，但我懷疑我正在做一些這種尷尬。如果任何人都能指出最後一部分的更清潔的方法，我會認識它。

我還沒有測試過，但注意遞歸調用LoadAllChildren自己調用。

public void SetupTree() 
{ 
    Assembly dataLib = Assembly.Load("Data"); 
    TreeNode theTree = new TreeNode("Assembly Data"); 

    foreach (Type type in dataLib.GetTypes()) 
    { 
     LoadAllChildren(dataLib, type, theTree); 
    } 

    treeView_left.Nodes.Add(theTree); //Optimisation - bind all nodes in one go rather than adding individually 
} 

private void LoadAllChildren(Assembly dataLib,Type type, TreeNode parentNode) 
{ 
    if (type.IsPublic && type.IsClass) 
    {    
     TreeNode node = new TreeNode(type.Name); 
     parentNode.Nodes.Add(node);   

     var types = dataLib.GetTypes().Where(x => x.IsSubclassOf(type)); 
     foreach (Type t in types) 
     { 
      LoadAllChildren(dataLib, t, node); 
     } 
    } 
} 

我希望這是足以讓你過欄，隨意問Q的
