c# - 遍历具有特定主题的 Outlook 电子邮件

Question

我目前正在研究下面的方法，它遍历我的收件箱中的电子邮件，但想知道如何过滤它们以专注于带有static subject 的，例如:nice weather。在搜索之后，我认为 folders.Items.Restrict() 可以提供帮助，但是我在 var fi = folder.Items 上得到了 condition is not valid。限制(“天气”)。我也试过var fi = folder.Items.Find("[Subject] = weather")，以确保条件有效，...但最终没有任何改进。

提前致谢

static void IterateMessages(Outlook.Folder folder)
    {
        string[] extensionsArray = {".csv"};
        //var fi = folder.Items;
        var fi = folder.Items.Restrict("weather");

        if (fi != null)
        {
            foreach (Object item in fi)
            {
                Outlook.MailItem mi = (Outlook.MailItem)item;
                var attachments = mi.Attachments;
                if (attachments.Count != 0)
                {
                    if (!Directory.Exists(basePath)
                    {
                        Directory.CreateDirectory(basePath);
                    }

                    // Loop through each attachment
                    for (int i = 1; i <= mi.Attachments.Count; i++)
                    {
                        Console.WriteLine("Processing: {0}", mi.Attachments[i].FileName);
                        mi.Attachments[i].SaveAsFile(basePath);
                        Console.WriteLine("Attachment: {0}" + " Saved to Path", mi.Attachments[i].FileName);
                    }
                }
            }
        }
    }

您的Restrict 参数格式似乎有误。试试这个:

var fi = folder.Items.Restrict("@SQL=\"urn:schemas:httpmail:subject\" like '%weather%'";
