[英]InvalidCastException while trying to deserialize JSON in C#
[英]I got an InvalidCastException error while trying to send a Email in C#
我想从我的C#(winform)应用程序发送一封电子邮件到地址展望但我在下面的行中遇到错误:
Outlook.MailItem mail =(Outlook.MailItem)_app.CreateItem(Outlook.OlItemType.olMailItem);
我收到以下错误:
无法将“Microsoft.Office.Interop.Outlook.ApplicationClass”类型的COM对象强制转换为接口类型“Microsoft.Office.Interop.Outlook._Application”。 此操作失败,因为由于以下错误,对IID为“{00063001-0000-0000-C000-000000000046}”的接口的COM组件的QueryInterface调用失败:库未注册。 (Exception de HRESULT:0x80040155)
我的完整代码是:
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 = 'paul.m@adt.org";
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;
}
}
