Attempting to connect to repository, getting 'DotCMIS.Exceptions.CmisConnectionException' and unsure why.

I am attempting to connect some C# code to an alfresco database, and I have two questions. Firstly, I am unsure of where to find the 'Repository ID', I have looked at the details page of the repository I need to connect to, but I didn't see anything that seemed to fit the bill.Additionally, when I

You are using wrong atom url :
for CMIS 1.0, the URL is:


http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.0/atom
‍‍‍

for CMIS 1.1, the URL is:


http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.1/atom
‍‍‍

and you don't need repositoryId parameter, you can write it like follwing


          try
            {
                Dictionary<string, string> parameters = new Dictionary<string, string>();
                parameters[DotCMIS.SessionParameter.BindingType] = BindingType.AtomPub;
                //parameters[DotCMIS.SessionParameter.AtomPubUrl] = "http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.1/atom";
                parameters[DotCMIS.SessionParameter.AtomPubUrl] = "http://localhost:8080/alfresco/api/-default-/public/cmis/versions/1.0/atom";
                parameters[DotCMIS.SessionParameter.User] = "admin";
                parameters[DotCMIS.SessionParameter.Password] = "admin";
                //parameters[DotCMIS.SessionParameter.RepositoryId] = "<repositoryId>";

                SessionFactory factory = SessionFactory.NewInstance();
                IList<IRepository> repos = factory.GetRepositories(parameters);
                ISession session = repos.ElementAt(0).CreateSession();
 
                IFolder rootFolder = session.GetRootFolder();
                foreach (ICmisObject cmisObject in rootFolder.GetChildren())
                {
                    Console.WriteLine(cmisObject.Name);
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.ToString());
            }

Thank you very much, that solved the exception, and I was able to find the repository ID.
Now the only problem is I am getting a 'Object Not Found Exception'.
I believe I need to direct it to the correct folder that contains the files I need to access, rather than the 'root folder', but I don't know what sort of syntax I should use. Would you be able to help me with this as well?

Edit: Scratch that, it connected correctly once I added the "ISession session = repos.ElementAt(0).CreateSession();" line of code you suggested. However I am still faced with my original problem of needing to search a specific folder, and I would still appreciate any help you could offer with that. But it's heartening to know that I am connected successfully.

I am using
<blockcode>
Folder folder = (Folder)session.GetObjectByPath("");

foreach (ICmisObject cmisObject in folder.GetChildren())
{
</blockcode>
But I do not know what to enter for the value in 'GetObjectByPath'. The folder I am attempting to search is called 'Test', and it's on the root folder. I can search the root folder and see 'Test' in the list, but I do not know what path to enter in order to actually search the 'Test' Folder.
If anyone could help me out with this, I would greatly appreciate it.

If your "Test" folder is direct under root folder,please write it like this


                IFolder folder1 = (IFolder)session.GetObjectByPath("/Test");
