如何在使用Microsoft.Office.Interop.Outlook从C#发送邮件时删除“代表”

Outlook.Application outlookApp = new Outlook.Application();
Outlook.NameSpace outlookNamespace = outlookApp.GetNamespace("MAPI");
Outlook.MAPIFolder inboxFolder = outlookNamespace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);

Outlook.Accounts accounts = outlookNamespace.Accounts;
Outlook.Account selectedAccount = null;

foreach (Outlook.Account account in accounts)
{
    if (account.DisplayName == "你的账户名称")
    {
        selectedAccount = account;
        break;
    }
}

Outlook.MailItem mailItem = outlookApp.CreateItem(Outlook.OlItemType.olMailItem) as Outlook.MailItem;
mailItem.SendUsingAccount = selectedAccount;

mailItem.To = "收件人邮箱地址";
mailItem.Subject = "邮件主题";
mailItem.Body = "邮件正文";

mailItem.Send();
