Saving attchment as file

Hi

I am using below code to access mail file attachments. I have two questions;

How can I only get unread messages?
How can I save file attachment into a file?

Thanks

Regards

      var inboxMessages = await graphClient
        .Users[user.Id]
        .MailFolders.Inbox
        .Messages
        .Request()
        .GetAsync();

      foreach(Microsoft.Graph.Message message in inboxMessages) {

        if (message.HasAttachments == true) {
          var attachments = await graphClient
            .Users[user.Id]
            .Messages[$ "{message.Id}"]
            .Attachments
            .Request()
            .GetAsync();

          foreach(var attachment in attachments) {
            if (attachment is FileAttachment) {
              FileAttachment fileAttachment = attachment as FileAttachment;

              //Save fileAttachment content to file here

            }
          }
        }
      }

If you want to check for unread messages, add a check to your if statement as follows:

if (message.HasAttachments is true && message.IsRead is false)

To save the file, you can do the following.

if (attachment.GetType() == typeof(FileAttachment))
{
//1. Cast from Attachment
var item = (FileAttachment)attachment;

                                       OR change foreach(var attachment in attachments) TO foreach (FileAttachment attachment in attachments)

                        //2. Put your directory path here. This will just put it to the location you are running your application. 
                        var folder = Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly().Location);

                        //3.  This will combine your directory and attachment name.
                        var filePath = Path.Combine(folder, item.Name);

                        //4.  This will save your file to the directory specified.
                        System.IO.File.WriteAllBytes(filePath, item.ContentBytes); OR System.IO.File.WriteAllBytes(filePath, attachment.ContentBytes) - Use the second option here if you use the second option in step 1 above.
                    }

For unread messages you can make the API call like this - https://graph.microsoft.com/v1.0/me/mailFolders/Inbox/messages?$filter=isRead ne true&$count=true
Get the attachments using as per the document and save it to the file system. You can download the attachment from the URI.
