List the contents of a folder and link to each file

Iterating the contents of a folder is straightforward using classes from System.IO, and listing them as links to the actual file just requires a bit of html added to each file name.

[C#]
using System.IO;
using System.Text;

DirectoryInfo dir;
StringBuilder sb  = new StringBuilder();
FileInfo[] files;

dir = new DirectoryInfo(Server.MapPath("."));
files = dir.GetFiles();
foreach (FileInfo f in files)
{
  sb.Append("<a href=\"" + f.Name.ToString() + "\">");
  sb.Append(f.Name.ToString() + "</a><br />");
}
Literal1.Text = sb.ToString();
[VB]
Imports System.Text
Imports System.IO

Dim dir As DirectoryInfo
Dim sb As StringBuilder = New StringBuilder()
Dim files() As FileInfo 'array of fileinfo objects

dir = New DirectoryInfo(Server.MapPath("."))

files = dir.GetFiles()
For Each f As FileInfo In files
  sb.Append("lt;a href=""" + f.Name.ToString() + """>")
  sb.Append(f.Name.ToString() + "lt;/a>lt;br />")
Next
Literal1.Text = sb.ToString()

It looks like Literal1 is not defined.

Literal1.Text = sb.ToString();

@Alan,

Yeah - you need to add a Literal control to your aspx file (which isn't featured in the article).
