c# - 在 C# 中创建 outlook .msg 文件

Question

我正在尝试使用我的 C# 代码创建 outlook .msg 格式文件。我使用了以下 2 个代码:

方法一:

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

            // Creating a new Outlook message from the Outlook Application instance
            Microsoft.Office.Interop.Outlook.MailItem msgInterop = (Microsoft.Office.Interop.Outlook.MailItem)(objOutlook.CreateItem(Microsoft.Office.Interop.Outlook.OlItemType.olMailItem));

            // Set recipient information
            msgInterop.To = "neha1@gmail.com";
            msgInterop.CC = "neha@gmail.com";

            // Set the message subject
            msgInterop.Subject = "Subject";

            // Set some HTML text in the HTML body
            msgInterop.HTMLBody = "<h3>HTML Heading 3</h3> <u>This is underlined text</u>";

            // Save the MSG file in local disk
            string strMsg = @"c:\\temp\TestInterop.msg";
            msgInterop.SaveAs(strMsg, Microsoft.Office.Interop.Outlook.OlSaveAsType.olMSG);

第二种方法:

 Redemption.RDOSession Session = new RDOSession();
                Redemption.RDOMail Msg = Session.CreateMessageFromMsgFile(@"c:\temp\YourMsgFile.msg");
                Msg.Sent = true;
                Msg.Subject = "test";
                Msg.Body = "test body";
                Msg.Recipients.AddEx("the user", "user@domain.demo", "SMTP", rdoMailRecipientType.olTo);
                Msg.Save();

这两种方法在执行时都会出错，如下所示:

System.Runtime.InteropServices.COMException (0x8004010F): Creating an instance of the COM component with CLSID {29AB7A12-B531-450E-8F7A-EA94C2F3C05F} from the IClassFactory failed due to the following error: 8004010f Exception from HRESULT: 0x8004010F.

我已经研究并发现了一些与平台的兼容性问题。我试图将平台从 32 位更改为 x64。仍然没有解决我的问题。

Answer 1

您执行此操作的机器上是否安装了 outlook 并处于可运行状态？错误是 com 组件没有注册，这通常意味着你只是从另一台没有注册 com 的机器上复制 dll。

所以要么安装outlook，要么安装这个
