最近自己做了一个小软件,一个文件浏览器,与windows的资源管理器相比,可以查看文件内容,而不用外部程序打开,支持多种文件格式,以后准备加入基于内容的搜索(打算用开源的dotLucene组件)。其中需要将树形控件序列化,查了很多资料,在codeproject找到一个vb.net写的,找了一个代码转换器转成了C#,修改了一下,改成了二进制序列化。贴在下面供需要的参考。

我修改过的C#源码:

using System;
using System.IO;
using System.Windows.Forms;
using System.Runtime.Serialization.Formatters.Binary;

namespace testAll
{
 /// <summary>
 /// TreeView串行化类
 /// </summary>
 public class TreeViewDataAccess
 {
  public TreeViewDataAccess(){}
  
  /// <summary>
  /// TreeViewData
  /// </summary>
  [Serializable()]
  public struct TreeViewData
  {
   public TreeNodeData[] Nodes;

   /// <summary>
   /// 递归初始化TreeView数据
   /// </summary>
   /// <param name="treeview"></param>
   public TreeViewData(TreeView treeview)
   {
    Nodes = new TreeNodeData[treeview.Nodes.Count];
    if (treeview.Nodes.Count == 0)
    {
     return;
    }
    for (int i = 0; i <= treeview.Nodes.Count - 1; i++)
    {
     Nodes[i] = new TreeNodeData(treeview.Nodes[i]);
    }
   }

   /// <summary>

   public void PopulateTree(TreeView treeview)
   {
    if (this.Nodes == null || this.Nodes.Length == 0)
    {
     return;
    }
    treeview.BeginUpdate();
    for (int i = 0; i <= this.Nodes.Length - 1; i++)
    {
     treeview.Nodes.Add(this.Nodes[i].ToTreeNode());
    }
    treeview.EndUpdate();
   }
  }

  /// <summary>

  public struct TreeNodeData
  {
   public string Text;
   public int ImageIndex;
   public int SelectedImageIndex;

   public bool Expanded;
   public object Tag;
   public TreeNodeData[] Nodes;

   /// <summary>

   public TreeNodeData(TreeNode node)
   {
    this.Text = node.Text;
    this.ImageIndex = node.ImageIndex;
    this.SelectedImageIndex = node.SelectedImageIndex;
    this.Checked = node.Checked;
    this.Expanded = node.IsExpanded;
    this.Nodes = new TreeNodeData[node.Nodes.Count];

    if ((!(node.Tag == null)) && node.Tag.GetType().IsSerializable)
    {
     this.Tag = node.Tag;
    }
