如何从Outlook文件夹中的每个邮件项目中检索SenderEmailAddress？

using Outlook = Microsoft.Office.Interop.Outlook;

// 连接到Outlook应用程序
Outlook.Application outlookApp = new Outlook.Application();

// 打开目标文件夹
Outlook.NameSpace outlookNamespace = outlookApp.GetNamespace("MAPI");
Outlook.MAPIFolder folder = outlookNamespace.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderInbox);

// 遍历邮件项目
foreach (object item in folder.Items)
{
    if (item is Outlook.MailItem mailItem)
    {
        // 检索SenderEmailAddress
        string senderEmailAddress = mailItem.SenderEmailAddress;

        // 处理SenderEmailAddress
        // ...
    }
}

// 释放资源
System.Runtime.InteropServices.Marshal.ReleaseComObject(outlookApp);
System.Runtime.InteropServices.Marshal.ReleaseComObject(outlookNamespace);
System.Runtime.InteropServices.Marshal.ReleaseComObject(folder);
