Mi piacerebbe migliorare la risposta di Neil: Molti dicono che non è consigliabile modificare il proprio web.config in fase di runtime. Ma ecco il codice come farlo.
//The path where the web.config file is located
string path = "~/Administrator/";
//Collections of aspx page names separated by a comma.
//Example content in a textbox: Default.aspx,Audit.aspx,
string strPages = txtPages.Text;
//This is string array where we are going to break down all name of aspx pages
//contained in strPages variable
string[] cdrPages = strValues.Split(',');
//This is the list where we are going to transfer the names of our aspx pages
//for faster searching of existing items
List<string> accesslist = new List<string>();
try
{
//1. Create Role
System.Web.Security.Roles.CreateRole(this.txtRoleName.Text);
//2. Open the Web Configuration --> make sure that you put the correct folder location of your web.config file
System.Configuration.Configuration config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration(path);
//3. Get All Specified Locations
ConfigurationLocationCollection myLocationCollection = config.Locations;
//4. Transfer the values of string[] strPages to List<string> accessList
for (int i = 0; i < strPages.Length; i++)
{
if (strPages[i].ToString() != null && strPages[i].ToString() != "")
{
accesslist.Add(strPages[i].ToString());
}
}
//5. Loop through the LocationCollections
foreach (ConfigurationLocation myLocation in myLocationCollection)
{
//6. Checks if myLocation exists in List<string> accessList
bool exists = accesslist.Exists(element => element == myLocation.Path);
//If Exists
if (exists) {
//7. Open the configuration of myLocation
System.Configuration.Configuration sub = myLocation.OpenConfiguration();
//8. Get the authorization section of specific location
AuthorizationSection section = (System.Web.Configuration.AuthorizationSection)sub.GetSection("system.web/authorization");
//9. Declare the Authorization Rule, in this case, we are allowing a new role to have an access to a specific page
AuthorizationRule autho = new System.Web.Configuration.AuthorizationRule(System.Web.Configuration.AuthorizationRuleAction.Allow);
//10. Add the New Role to Authorization Section
autho.Roles.Add(this.txtRoleName.Text);
section.Rules.Add(autho);
//11. Save the "sub", or the specific location inside the web.config file.
sub.Save();
}
}
message.InnerHtml = "Role Successfully Added!";
message.Attributes.Add("class", "msg_info");
}
catch {
message.InnerHtml = "Saving Failed";
message.Attributes.Add("class", "msg_error");
}
Questo può essere un brutto codice, ma sicuramente funzionerà. - Jan Russel 'Rusty Programmer' Calachan

Potrebbe essere utile se si potesse incollare l'intero contenuto del file di configurazione. –
