读取文件夹文件并绑定DataGrid

//这是在上次做的博客系统中用到的一项技术，感觉有用处，拿出来分享！

public DataTable Binde(string FullPath)
    {
        try
        {
            //动态创建数据表
            DataTable dt = new DataTable();
            DataRow dr;
            //创建数据表结构，即要显示的信息。
            dt.Columns.Add(new DataColumn("名称", System.Type.GetType("System.String")));
            dt.Columns.Add(new DataColumn("大小", System.Type.GetType("System.String")));
            dt.Columns.Add(new DataColumn("创建日期", System.Type.GetType("System.String")));
            dt.Columns.Add(new DataColumn("操作", System.Type.GetType("System.String")));
            dt.Columns.Add(new DataColumn("路径", System.Type.GetType("System.String")));
            //为每一行添加数据            
            DirectoryInfo dtif = new DirectoryInfo(Server.MapPath(FullPath));
            FileInfo[] fi = dtif.GetFiles();
            foreach (FileInfo d in fi)
