我想使用此处所述的通过 Outlook 发送电子邮件。只要我已经打开 Outlook,它就可以正常工作。因此,例如,如果 Outlook 被最小化并且我执行我的代码,那么我可以发送电子邮件就好了。但如果 Outlook 已关闭,则会出现异常:
{System.Runtime.InteropServices.COMException (0x80004004): Operation aborted (Exception from HRESULT: 0x80004004 (E_ABORT))
at Microsoft.Office.Interop.Outlook._MailItem.get_Recipients()
at OutlookExample.Form1.btnSendEmail_Click(Object sender, EventArgs e) in C:\Users\abc\Documents\Visual Studio 2008\Projects\OutlookExample\OutlookExample\Form1.cs:line 28}
这是代码:
using Outlook = Microsoft.Office.Interop.Outlook;
...
private void btnSendEmail_Click(object sender, EventArgs e)
{
try
{
Outlook.Application oApp = new Outlook.Application();
Outlook.MailItem oMsg = Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);
oMsg.HTMLBody = "Hello, here is your message!";
oMsg.Subject = "This is a test message";
Outlook.Recipients oRecips = (Outlook.Recipients)oMsg.Recipients;
Outlook.Recipient oRecip = (Outlook.Recipient)oRecips.Add("rhr@sonlinc.dk");
oRecip.Resolve();
oMsg.Send();
oRecip = null;
oRecips = null;
oMsg = null;
oApp = null;
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
为什么这不起作用?
编辑:这是解决方案
using Outlook = Microsoft.Office.Interop.Outlook;
...
private void btnSendEmail_Click(object sender, EventArgs e)
{
try
{
Outlook.Application oApp = new Outlook.Application();
// These 3 lines solved the problem
Outlook.NameSpace ns = oApp.GetNamespace("MAPI");
Outlook.MAPIFolder f = ns.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);
System.Threading.Thread.Sleep(5000); // test
Outlook.MailItem oMsg = Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem);
oMsg.HTMLBody = "Hello, here is your message!";
oMsg.Subject = "This is a test message";
Outlook.Recipients oRecips = (Outlook.Recipients)oMsg.Recipients;
Outlook.Recipient oRecip = (Outlook.Recipient)oRecips.Add("rhr@sonlinc.dk");
oRecip.Resolve();
oMsg.Send();
oRecip = null;
oRecips = null;
oMsg = null;
oApp = null;
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
