當Outlook打開時，Microsoft.Office.Interop.Outlook確認電子郵件不起作用

Question

我想在用戶提交表單時發送確認電子郵件。我有smtp privlage問題，所以我想通過Outlook來做到這一點。當Outlook未打開時，代碼正常工作enter link description here，但只是掛起。任何想法如何解決這個或周圍的方式？

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

嘗試檢查是否有已經打開的Outlook實例，如果有人使用它來發送郵件。如果沒有，則創建新的實例。

（未經測試）這應該讓你開始：

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
