C#和EWS如何将消息保存为电子邮件而不是草稿

using Microsoft.Exchange.WebServices.Data;

// 创建EWS客户端对象
ExchangeService service = new ExchangeService(ExchangeVersion.Exchange2010_SP2);
service.Credentials = new WebCredentials("username", "password");
service.Url = new Uri("https://mail.example.com/EWS/Exchange.asmx");

// 创建电子邮件消息对象
EmailMessage message = new EmailMessage(service);

// 设置电子邮件消息的属性
message.Subject = "Hello";
message.Body = new MessageBody("This is a test email");
message.ToRecipients.Add("recipient@example.com");

// 将消息保存为电子邮件
message.IsDraft = false;

// 保存电子邮件到邮箱中
message.Save(WellKnownFolderName.Inbox);

Console.WriteLine("Message saved as email successfully");
