Check this link. Introduction to Outlook Programmingwill explain things more clearly.
检查此链接。Outlook 编程简介将更清楚地解释事情。
You could loop through the mailitems. Sample code
您可以遍历邮件项目。示例代码
using System.Runtime.InteropServices;
using OutLook = Microsoft.Office.Interop.Outlook;
using Office = Microsoft.Office.Core;
OutLook.Application oApp;
OutLook._NameSpace oNS;
OutLook.MAPIFolder oFolder;
OutLook._Explorer oExp;
oApp = new OutLook.Application();
oNS = (OutLook._NameSpace)oApp.GetNamespace("MAPI");
oFolder = oNS.GetDefaultFolder(OutLook.OlDefaultFolders.olFolderInbox);
oExp = oFolder.GetExplorer(false);
oNS.Logon(Missing.Value, Missing.Value, false, true);
OutLook.Items items = oFolder.Items;
foreach (OutLook.MailItem mail in items)
{
if (mail.UnRead == true)
{
}
}
Edit: Reference other folders
编辑： 参考其他文件夹
oFolder.Folders["Foldername"]

There's some examples of accessing Outlook folders here, one of which deals specifically with unread mail.
有访问Outlook文件夹的一些例子在这里，其中一个有未读的邮件专门处理。
Edit: There's a KB article specifically about accessing folders from C#, Programming samples that can reference items and folders in Outlook by using Visual C# .NET
编辑：有一篇专门关于从 C# 访问文件夹的知识库文章，Programming samples that can reference items and folder in Outlook by using Visual C# .NET
To open another user's folder, use GetSharedDefaultFolder

Looping through all items in a folder is a terrible idea, especially if you are working against an online Exchange store. Items.Find/FindNextor Items.Restrictis the way to go.
遍历文件夹中的所有项目是一个糟糕的主意，尤其是当您使用在线 Exchange 商店时。Items.Find/FindNext或者Items.Restrict是要走的路。
Find/FindNext:
查找/查找下一个：
OutLook.Items items = oFolder.Items;
OutLook.MailItem mail = items.Find("[Unread] = true");
while (mail != null)
{
MessageBox.Show(mail.Subject);
mail = items.FindNext();
}
Items.Restrict:
Items.Restrict:
OutLook.Items items = oFolder.Items.Restict("[Unread] = true")
foreach (OutLook.MailItem mail in items)
{
MessageBox.Show(mail.Subject);
}

foreach (Object Unreadmail in folderItems)
{
if ((Unreadmail as Outlook.MailItem) != null && (Unreadmail as Outlook.MailItem).UnRead == true)
{
//DO Your action Here
}
}
