当Outlook打开时，Microsoft.Office.Interop.Outlook确认电子邮件不起作用

Question

我想在用户提交表单时发送确认电子邮件。我有smtp privlage问题，所以我想通过Outlook来做到这一点。当Outlook未打开时，代码正常工作enter link description here，但只是挂起。任何想法如何解决这个或周围的方式？

try

// Create the Outlook application. 
Outlook.Application oApp = new Outlook.Application(); 

// Create a new mail item. 
Outlook.MailItem oMsg = (Outlook.MailItem)oApp.CreateItem(Outlook.OlItemType.olMailItem); 
// Set HTMLBody. 
//add the body of the email 
oMsg.HTMLBody = "Hello, Jawed your message body will go here!!"; 

//Subject line 
oMsg.Subject = "Your Subject will go here."; 

// Add a recipient. 
Outlook.Recipients oRecips = (Outlook.Recipients)oMsg.Recipients; 
// Change the recipient in the next line if necessary. 
Outlook.Recipient oRecip = (Outlook.Recipient)oRecips.Add("email@address.com"); 
oRecip.Resolve(); 

// Send. 
((Outlook._MailItem)oMsg).Send(); 


// Clean up. 
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(oMsg); 
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(oRecip); 
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(oRecips); 
System.Runtime.InteropServices.Marshal.FinalReleaseComObject(oApp); 
}//end of try block 

catch (Exception ex) 
{ 
}//end of catch

尝试检查是否有已经打开的Outlook实例，如果有人使用它来发送邮件。如果没有，则创建新的实例。

（未经测试）这应该让你开始：

Outlook.Application oApp; 
try { 
    oApp = (Outlook.Application)Marshal.GetActiveObject("Outlook.Application"); 
} 
catch() { 
    oApp = new Outlook.Application(); 
} 

// use oApp to send the stuff, it will either be the existing instance or a new instance
