A quick and easy way to load files and directories contained in a specified folder into a DataTable.

[code language="C#"]

using System;
using System.Data;
using System.IO;

namespace KeithRull.Utilities
{
    /// <summary>
    /// A collection of methods that handles the processing of FileSystem data and information
    /// </summary>
    public sealed class FileSytem
    {
        private FileSytem(){}

        /// <summary>
        /// A method that accepts a string that points to a directory,
        /// reads that folders contents and convert that data into a DataTable
        /// </summary>
        /// <param name="directory">the directory to browse</param>
        /// <returns>a DataTable containing the information about the supplied directory</returns>
        public static DataTable FileSystemToDataTable(string directory)
        {
            //read the folder       
            DirectoryInfo directoryInfo = new DirectoryInfo(directory);

            //create our datatable that would hold the list
            //of folders in the specified directory
            DataTable filesystem = new DataTable();

            /* Add the columns to our datatable
             * You can add as many colums as you like.
             * for this demo, we will just be adding this columns
             * */
            filesystem.Columns.Add(new DataColumn("Name"));
            filesystem.Columns.Add(new DataColumn("FullName"));
            filesystem.Columns.Add(new DataColumn("CreationTime"));
            filesystem.Columns.Add(new DataColumn("LastWriteTime"));

            //loop thru each FileSystemInfo object in the specified directory
            foreach (FileSystemInfo fileSystemInfo in directoryInfo.GetFileSystemInfos())
            {
                //create a new row in ould filesystem table
                DataRow dataRow = filesystem.NewRow();

                //assign the values to our table members
                dataRow["Name"] = fileSystemInfo.Name;
                dataRow["FullName"] = fileSystemInfo.FullName;
                dataRow["CreationTime"] = fileSystemInfo.CreationTime;
                dataRow["LastWriteTime"] = fileSystemInfo.LastWriteTime;

                // add the datarow to our datatable
                filesystem.Rows.Add(dataRow);
            }

            //return our table
            return filesystem;
        }
    }
}

[/code]

Sample usage would be as follows:

[code language="C#"]

string directory = Server.MapPath(""); //load a specific path in our web server
DataGrid1.DataSource = KeithRull.Utilities.FileSytem.FileSystemToDataTable(directory);
DataGrid1.DataBind();

[/code]

or

[code language="C#"]

string directory = "c:\"; //just point to a folder in the machine
DataGrid1.DataSource = KeithRull.Utilities.FileSytem.FileSystemToDataTable(directory);
DataGrid1.DataBind();

[/code]

*update:  Here's the VB.NET version as requested

[code language="VB.NET"]

Imports System
Imports System.Data
Imports System.IO
Namespace KeithRull.Utilities

 Public NotInheritable Class FileSytem

   Private Sub New()
   End Sub

   Public Shared Function FileSystemToDataTable(ByVal directory As String) As DataTable

     Dim directoryInfo As DirectoryInfo = New DirectoryInfo(directory)

     Dim filesystem As DataTable = New DataTable

     filesystem.Columns.Add(New DataColumn("Name"))
     filesystem.Columns.Add(New DataColumn("FullName"))
     filesystem.Columns.Add(New DataColumn("CreationTime"))
     filesystem.Columns.Add(New DataColumn("LastWriteTime"))

     For Each fileSystemInfo As FileSystemInfo In directoryInfo.GetFileSystemInfos
       Dim dataRow As DataRow = filesystem.NewRow
       dataRow("Name") = fileSystemInfo.Name
       dataRow("FullName") = fileSystemInfo.FullName
       dataRow("CreationTime") = fileSystemInfo.CreationTime
       dataRow("LastWriteTime") = fileSystemInfo.LastWriteTime
       filesystem.Rows.Add(dataRow)
     Next

     Return filesystem

   End Function

 End Class

End Namespace
