我特林從我的C#(WinForm的)應用程序發送電子郵件至ADRESS前景,但我上線getteing錯誤如下:我試圖在C#中發送電子郵件了InvalidCastException錯誤
Outlook.MailItem mail =(Outlook.MailItem)_app.CreateItem(Outlook.OlItemType.olMailItem);
我得到了以下錯誤:
Unable to cast COM object of type ‘Microsoft.Office.Interop.Outlook.ApplicationClass’ to interface type ‘Microsoft.Office.Interop.Outlook._Application’. This operation failed because the QueryInterface call on the COM component for the interface with IID ‘{00063001-0000-0000-C000-000000000046}’ failed due to the following error: Library not registered. (Exception de HRESULT : 0x80040155)
我完整的代碼:
void SendEmailAuto()
{
try
{
OpenFileDialog attachment = new OpenFileDialog();
attachment.Title = "Select a file to send";
attachment.ShowDialog();
Outlook._Application _app = new Outlook.Application();
Outlook.MailItem mail =mail= (Outlook.MailItem)_app.CreateItem(Outlook.OlItemType.olMailItem);
mail.To = '[email protected]";
mail.Subject = "Text";
mail.Body = "Funding Request Team";
if (attachment.FileName.Length > 0)
{
mail.Attachments.Add(attachment.FileName, Outlook.OlAttachmentType.olByValue, 1, attachment.FileName);
mail.Importance = Outlook.OlImportance.olImportanceHigh;
((Outlook.MailItem)mail).Send();
}
else
{
MessageBox.Show("You are kindly requested to attach a document.", "MISSING FILE", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
}
catch (Exception ex)
{
string msg = ex.Message;
}
}
你使用outlook發送電子郵件或網絡服務器?如果你是從服務器發送它,爲什麼不切斷前景中間人呢? – Takarii
也許[這個問題](http://stackoverflow.com/questions/17810163/outlook-interop-exception-displaying-new-mailitem)可能有幫助嗎? –
Takarii ..感謝您的回覆。我使用Outlook將郵件發送到另一個Outlook地址。從展望到展望 – Christ
