How to get list of all domains in Active Directory using C#

Can anyone please help me to get all the domains in Active Directory. I have tried many times, but all the programs are listing only the current working domain.

How can I do this?

I had some issues getting LeeMobile's code to work in my case bacause it was trying to find my application's current domain context while running forest.Domains. I was able to get around it by doing something like this.

Forest forest = Forest.GetForest(new DirectoryContext(DirectoryContextType.Forest, "yourForestDomain", "username", "password"));
DomainCollection domains = forest.Domains;

You could also use System.DirectoryServices.ActiveDirectory.Forest.GetCurrentForest().Domains

var domains = Forest.GetCurrentForest().Domains.Cast<Domain>();
foreach (var domain in domains)
{
    Console.WriteLine(domain.Name);
}

Domain domain = Domain.GetDomain(new DirectoryContext(DirectoryContextType.Domain, "yourDomain", "username", "password"));

Forest forest = domain.Forest;

DomainCollection domains = forest.Domains;

The above uses the System.DirectoryServices.ActiveDirectory namespace. It'll give you a domain collection containing all the domains that are in the same forest as your given domain.

Using DirectorySearcher you can connect and read the structure of one Active Directory, including the structure (organization units, groups, users, computers, domain controllers). In order to connect to a different domain, you would need credentials of that other domain. We had problems in connecting to another domain from a machine that belongs to a different domain than the target one. I'm also curious if that's even possible.
