 在WinForm中添加一个treeview,imagelist控件后

加入如下代码就完成了一个资源管理器：

private   void  FolderTree_AfterSelect( object  sender, System.Windows.Forms.TreeViewEventArgs e)
         ... {
            if(e.Node.Text.ToString()!="我的电脑")
                EnumDirectories(e.Node);
            else
                EnumDrives(e.Node);
        }

驱动盘：

  private   void  EnumDrives(TreeNode ParentNode)
         ... {
            if(ParentNode.Nodes.Count==0)
            ...{   
                FolderTree.SelectedNode=ParentNode;
                foreach(string drive in Directory.GetLogicalDrives())
                ...{
                    TreeNode TempNode=new TreeNode();
                    TempNode.Text=drive.Substring(0,drive.Length-1);
                    TempNode.Tag=drive;

                    TempNode.ImageIndex=1;
                    TempNode.SelectedImageIndex=1;
 
                    FolderTree.SelectedNode.Nodes.Add(TempNode);
                    FolderTree.SelectedNode.Nodes[FolderTree.SelectedNode.Nodes.Count-1].EnsureVisible();
                }
            }
        }

目录文件：

private   void  EnumDirectories(TreeNode ParentNode)
         ... {
            if(ParentNode.Nodes.Count==0)
            ...{
                FolderTree.SelectedNode=ParentNode;
                string DirectoryPath=ParentNode.Tag.ToString();
                if(DirectoryPath.Substring(DirectoryPath.Length-1)!=@"")...{}
                    DirectoryPath+=@"";
                try
                ...{
                    foreach(string directory in Directory.GetDirectories(DirectoryPath))
                    ...{
                        TreeNode TempNode=new TreeNode();
                        TempNode.Text=directory.Substring(directory.LastIndexOf(@"")+1);
                        TempNode.Tag=directory;

                        TempNode.ImageIndex=3;
                        TempNode.SelectedImageIndex=2;

                        FolderTree.SelectedNode.Nodes.Add(TempNode);//SelectedNode注意一下
                        FolderTree.SelectedNode.Nodes[FolderTree.SelectedNode.Nodes.Count-1].EnsureVisible();
                    }
                }
                catch(Exception)
                ...{
                }
            }
        }
