Inspecting your Trusts in .NET 2.0

One of the great things about .NET 2.0 is the new System.DirectoryServices.ActiveDirectory namespace. It contains a plethora of previously either obscure or difficult things to do using Ds* or NetApi* API calls. I was troubleshooting a trust relationship at a client and was digging how easy this was to do in 2.0:

    public static void ShowAllTrusts()
    {
        Domain domain = Domain.GetCurrentDomain();
        int i = 0;
 
        foreach (TrustRelationshipInformation tri in domain.GetAllTrustRelationships())
        {
            Console.WriteLine("Trust #{0}", ++i);
            Console.WriteLine("=============================================");
            Console.WriteLine(
                "Source Name: {0}",
                tri.SourceName
                );
 
            Console.WriteLine(
                "Target Name: {0}",
                tri.TargetName
                );
 
            Console.WriteLine(
                "Trust Direction: {0}",
                tri.TrustDirection
                );
 
            Console.WriteLine(
                "Trust Type: {0}",
                tri.TrustType
                );
 
 
            string verifiedMsg = "true";
 
            try
            {
                domain.VerifyTrustRelationship(
                    Domain.GetDomain(
                        new DirectoryContext(
                            DirectoryContextType.Domain,
                            tri.TargetName
                            )
                        ),
                    tri.TrustDirection
                    );
            }
            catch (Exception ex)
            {
                verifiedMsg = ex.Message;
            }
 
            Console.WriteLine(
                "Verified: {0}",
                verifiedMsg        
                );
 
            Console.WriteLine("=============================================");
            Console.WriteLine();
        }
    }

That took all of 5 minutest to code and test using SnippetCompiler. Very cool.
