如何在Outlook中使用C#将当前用户电子邮件地址转换为字符串？

using Outlook = Microsoft.Office.Interop.Outlook;

Outlook.Application outlookApp = new Outlook.Application();
Outlook.NameSpace outlookNamespace = outlookApp.GetNamespace("MAPI");
Outlook.Recipient currentUser = outlookNamespace.CurrentUser;

string emailAddress = currentUser.AddressEntry.GetExchangeUser().PrimarySmtpAddress;

using Outlook = Microsoft.Office.Interop.Outlook;

namespace OutlookEmailExample
{
    class Program
    {
        static void Main(string[] args)
        {
            Outlook.Application outlookApp = new Outlook.Application();
            Outlook.NameSpace outlookNamespace = outlookApp.GetNamespace("MAPI");
            Outlook.Recipient currentUser = outlookNamespace.CurrentUser;

            string emailAddress = currentUser.AddressEntry.GetExchangeUser().PrimarySmtpAddress;

            Console.WriteLine("Current user email address: " + emailAddress);
        }
    }
}
