Question

我有一个任务可以从特定的电子邮件中下载/保存附件

我已经从许多网站的引用中编写了代码（包括堆栈溢出答案），但Console应用程序无法保存附件。

这是我的代码

 try
            {

                Microsoft.Office.Interop.Outlook.Application MyApp = new Microsoft.Office.Interop.Outlook.Application();

                Microsoft.Office.Interop.Outlook.NameSpace MailNS = MyApp.GetNamespace("mapi");

                Microsoft.Office.Interop.Outlook.MAPIFolder MyInbox = null;

                MyInbox = MailNS.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);

                Microsoft.Office.Interop.Outlook._MailItem InboxMailItem = null;

                Microsoft.Office.Interop.Outlook.Items oItems = MyInbox.Items;

                Microsoft.Office.Interop.Outlook.MailItem mailitem = MyApp.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem);

                string Query = "[Subject] = 'Test'";

                InboxMailItem = (Microsoft.Office.Interop.Outlook._MailItem)oItems.Find(Query);

                while(InboxMailItem != null)
                {
                    Outlook.Attachments attachments =  InboxMailItem.Attachments;
                    if (attachments != null && attachments.Count > 0)
                    {
                        for (int i = 0; i <= attachments.Count; i++)
                        {
                            Outlook.Attachment attachment = attachments[i];

                            string filename = Path.Combine(@"C:\Users\u532246\Desktop", attachment.FileName);
                            attachment.SaveAsFile(filename);

                            Console.WriteLine("berhasil");
                            Console.ReadLine();
                        }
                    }
                 break;
                }

                MyApp = null;

            }

            catch (Exception ex)
            {

            }

也许我在这里做错了，因为我对这种任务是陌生的..

谢谢您的帮助，我真的很感激

问题似乎是附件数组索引从 1 开始，而不是从 0 开始，正如您在发布的示例代码中所使用的那样。

所以您的 for 循环代码应该是：

for (int i = 1; i <= attachments.Count; i++)
{
    Outlook.Attachment attachment = attachments[i];

    string filename = Path.Combine(@"C:\Users\u532246\Desktop", attachment.FileName);
    attachment.SaveAsFile(filename);

    Console.WriteLine("berhasil");
    Console.ReadLine();
}
