This sample code demonstrates how to programmatically list all SharePoint Portal Server 2003 or Windows SharePoint Services v2.0 site groups and the users they contain (exception handling omitted). For simplicity the example code below demonstrates how to write this information to a basic text file.

In C#

using System;
using System.IO;
using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;

StreamWriter Writer = File.CreateText(@"C:\Temp\GroupsAndUsers.txt");

try
{
   SPWeb PortalWeb = SPControl.GetContextWeb(Context);
   SPRoleCollection PortalGroups = PortalWeb.Roles;

   foreach(SPRole Group in PortalGroups)
   { 
      Writer.WriteLine(String.Format("Group: {0}", Group.Name));

      foreach(SPUser User in Group.Users)
      {
        Writer.WriteLine(String.Format("- {0}", User.Name);
      }
   }
}
finally
{
   Writer.Close();
}

In VB.NET

Imports System
Imports System.IO
Imports Microsoft.SharePoint
Imports Microsoft.SharePoint.WebControls

Dim Writer As StreamWriter = File.CreateText("C:\Temp\GroupsAndUsers.Text")

Try
   Dim PortalWeb As SPWeb = SPControl.GetContextWeb(Context)
   Dim PortalGroups As SPRoleCollection = PortalWeb.Roles

   For Each Group As SPRole In PortalGroups
      Writer.WriteLine(String.Format("Group: {0}", Group.Name))
 
      For Each User As SPUser In Group.Users
         Writer.WriteLine(String.Format("- {0}", User.Name
      Next
   Next
Finally
   Writer.Close()
End Try
