Traversing through IGraphServiceCollectionPage

Question

I have made a List of graph service collection page but I need to put if loop to see if email exits in the list. Can someone help me t traverse. This is the code

var authProvider = await GetAuthProvider();

        GraphServiceClient graphClient = new GraphServiceClient(authProvider);


            List<User> users = new List<User>();
            var user = await graphClient.Users.Request().GetAsync();
            users.AddRange(user.CurrentPage.OfType<User>());
            
            while (user.NextPageRequest != null)
            {
                user = await user.NextPageRequest.GetAsync();
                users.AddRange(user.CurrentPage.OfType<User>());
                
            }

I want to know if the string {email} exits in users if yes return true if not return exception. but cannot convert as getting error cannot convert type string to Users

As per your code, it doesn't contain email you have to go 1 level down. if you want to get the mail you need to use Messages.

This is the demo API to get emails in graph explorer - https://graph.microsoft.com/v1.0/users/{user ID}/messages

The best way is to debug your code.
