How to retrieve from email from Exchange server Mail Account ?

Dear All,

I get the email in my mail box from hardikramwani@hotmail.com.

I need to retrieve the from email address but i am unable to get this.

Following is code i am using.

Folder boundFolder = Folder.Bind(service, WellKnownFolderName.Inbox);
                FindItemsResults<Item> unreadMessages = boundFolder.FindItems(unreadSearchFilter, itemView);

                if (unreadMessages != null && unreadMessages.Items != null && unreadMessages.Items.Count > 0)
                {
                    foreach (EmailMessage message in unreadMessages)
                    {

                        string subject = message.Subject.ToString();
                        string strfromEmail = message.From.Address.ToString(); // I got Error of Object Refrence
                        string strDisplayName = message.From.Name.ToString();

How can i retrieve from email using C#? 

Thanks and regards,
