C# 遍曆檔案夾 建立樹

今天做一個自動報表的功能,需要遍曆某個目錄下的所有的檔案和檔案夾,並在樹上顯示出來.

代碼如下:

 private void GetFileInfo(string filePath, TreeNode node)
        {
            DirectoryInfo directoryInfo = new DirectoryInfo(filePath);
            try
            {
                foreach (DirectoryInfo childDirectoryInfo in directoryInfo.GetDirectories())
                {
                    TreeNode directoryNode = new TreeNode(childDirectoryInfo.Name.ToString());
                    directoryNode.Tag = childDirectoryInfo.Name.ToString();
                    GetFileInfo(filePath + "\\" + childDirectoryInfo.Name.ToString(), directoryNode);
                    node.Nodes.Add(directoryNode);
                }
                foreach (FileInfo fileInfo in directoryInfo.GetFiles("*.html"))
                {
                    TreeNode leafNode = new TreeNode();
                    leafNode.Text = fileInfo.Name.ToString().Substring(0,fileInfo.Name.ToString().IndexOf(".html"));
                    leafNode.Tag = fileInfo.Name.ToString();
                    node.Nodes.Add(leafNode);
                }

 }
            catch
            {

            }
        }

使用介紹:

            TreeNode treenode = new TreeNode();
            treenode.Text = "報表樹";
            GetFileInfo(@"C:\AutoReport", treenode);
            this.treeView1.Nodes.Add(treenode);

 

 

聲明：

這段代碼，只能夠顯示html的，如果您要使用，請視情況修改   foreach (FileInfo fileInfo in directoryInfo.GetFiles("*.html"))
這個。。。。
