Here's the implementation that I came up with for writing the registry keys in .NET.
Thanks for setting me in the right direction, Ben.
using System;
using System.Collections.Generic;
using Microsoft.Win32;
namespace ReportManagement
{
class ReportDownloader
{
[STAThread]
static void Main(string[] args)
{
const string domainsKeyLocation = @"Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap\Domains";
const string domain = @"newsite.com";
const int trustedSiteZone = 0x2;
var subdomains = new Dictionary<string, string>
{
{"www", "https"},
{"www", "http"},
{"blog", "https"},
{"blog", "http"}
};
RegistryKey currentUserKey = Registry.CurrentUser;
currentUserKey.GetOrCreateSubKey(domainsKeyLocation, domain, false);
foreach (var subdomain in subdomains)
{
CreateSubdomainKeyAndValue(currentUserKey, domainsKeyLocation, domain, subdomain, trustedSiteZone);
}
//automation code
}
private static void CreateSubdomainKeyAndValue(RegistryKey currentUserKey, string domainsKeyLocation,
string domain, KeyValuePair<string, string> subdomain, int zone)
{
RegistryKey subdomainRegistryKey = currentUserKey.GetOrCreateSubKey(
string.Format(@"{0}\{1}", domainsKeyLocation, domain),
subdomain.Key, true);
object objSubDomainValue = subdomainRegistryKey.GetValue(subdomain.Value);
if (objSubDomainValue == null || Convert.ToInt32(objSubDomainValue) != zone)
{
subdomainRegistryKey.SetValue(subdomain.Value, zone, RegistryValueKind.DWord);
}
}
}
public static class RegistryKeyExtensionMethods
{
public static RegistryKey GetOrCreateSubKey(this RegistryKey registryKey, string parentKeyLocation,
string key, bool writable)
{
string keyLocation = string.Format(@"{0}\{1}", parentKeyLocation, key);
RegistryKey foundRegistryKey = registryKey.OpenSubKey(keyLocation, writable);
return foundRegistryKey ?? registryKey.CreateSubKey(parentKeyLocation, key);
}
public static RegistryKey CreateSubKey(this RegistryKey registryKey, string parentKeyLocation, string key)
{
RegistryKey parentKey = registryKey.OpenSubKey(parentKeyLocation, true); //must be writable == true
if (parentKey == null) { throw new NullReferenceException(string.Format("Missing parent key: {0}", parentKeyLocation)); }
RegistryKey createdKey = parentKey.CreateSubKey(key);
if (createdKey == null) { throw new Exception(string.Format("Key not created: {0}", key)); }
return createdKey;
}
}
}
