开发Outlook-2010插件。
Main addin类正在启动像这样的异步任务并声明 一个静态事件,可以从其他形式中获取:
int ProcesadosArchivado = 0;
public delegate void OnFileArchivedDelegate (int NumFilesArchived, string NameArchived);
public static event OnFileArchivedDelegate OnFileArchivedEvent = delegate { };
private void ThisAddIn_Startup(object sender, System.EventArgs e)
{
Thread hiloArchivado = new Thread(DoArchiveBackground);
hiloArchivado.Start();
}
private void DoArchiveBackground()
{
try
{
Outlook.Application app = null;
Outlook._NameSpace ns = null;
Outlook.MailItem item = null;
//Outlook.MAPIFolder inboxFolder = null;
DateTime MyDateTime = DateTime.Now.AddMonths(-3);
app = new Outlook.Application();
ns = app.GetNamespace("MAPI");
ns.Logon(null, null, false, false);
Outlook.Stores store;
Outlook.MAPIFolder rootFolder = null;
store = Application.Session.Stores;
foreach (Outlook.Store storeClass in store.Session.Stores)
{
rootFolder = storeClass.GetRootFolder();
}
Outlook.MAPIFolder folder = rootFolder.Folders["ARCHIVAR"];
Outlook.MAPIFolder ArchivarFolder = ns.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);
// inboxFolder = ns.GetDefaultFolder(Microsoft.Office.Interop.Outlook.OlDefaultFolders.olFolderInbox);
for (int i = 1; i <= ArchivarFolder.Items.Count; i++)
{
try
{
item = (Microsoft.Office.Interop.Outlook.MailItem)ArchivarFolder.Items[i];
ProcesadosArchivado += 1;
OnFileArchivedDelegate myEvent = OnFileArchivedEvent;
myEvent.Invoke(ProcesadosArchivado, item.Subject);
//Messate iteration
}
catch (Exception ex)
{
throw;
}
}
}
//Catch folder iteration
catch (Exception ex)
{
throw;
}
}
然后我从其他表单中接受静态事件并尝试使用更新某些控件 InvokeRequired和delegates:
public partial class ArchiveForm : Form
{
private delegate void UpdateControlDelegate (Control control,string Property,string value);
public ArchiveForm()
{
InitializeComponent();
this.Load += new EventHandler(ArchiveForm_Load);
}
void ArchiveForm_Load(object sender, EventArgs e)
{
ThisAddIn.OnFileArchivedEvent += new ThisAddIn.OnFileArchivedDelegate(ThisAddIn_OnFileArchivedEvent);
}
void ThisAddIn_OnFileArchivedEvent(int NumFilesArchived, string NameArchived)
{
updateControls(NumFilesArchived,NameArchived);
}
void UpdateControl(Control control,string Property,string value)
{
PropertyInfo prop = control.GetType().GetProperty("Text");
prop.SetValue(control,
Convert.ChangeType(value, prop.PropertyType), null);
}
private void updateControls(int NumFilesArchived, string NameArchived)
{
if (lblArchivado.InvokeRequired)
{
UpdateControlDelegate del = new UpdateControlDelegate(UpdateControl);
//del.BeginInvoke(lblArchivado, "Text", "Archivados: " + NumFilesArchived.ToString(), null, null);
del.Invoke(lblArchivado, "Text", "Archivados: " + NumFilesArchived.ToString());
}
else
this.lblArchivado.Text = "Archivados: " + NumFilesArchived.ToString();
if (lblAsunto.InvokeRequired)
{
UpdateControlDelegate del = new UpdateControlDelegate(UpdateControl);
//del.BeginInvoke(lblAsunto, "Text", "Asunto: " + NameArchived, null, null);
del.Invoke(lblAsunto, "Text", "Asunto: " + NameArchived);
}
else
this.lblAsunto.Text = "Asunto: " + NameArchived;
}
}
我得到Cross-Head无效的操作异常 到达线时:
* prop.SetValue(control,Convert.ChangeType(value,prop.PropertyType),null); *
它正在通过invoreRequired并调用委托,所以我真的没有 得到为什么我得到这个例外。
答案 0 :(得分:0)
好的,经过一些研究我改变了这个:
del.Invoke(lblAsunto, "Text", "Asunto: " + NameArchived);
进入这个:
this.Invoke(del, new object[] { lblAsunto, "Text", "Asunto: " + NameArchived });
它现在正在运作。

您不应该使用辅助线程中的Outlook对象模型。它必然会产生问题。如果从与返回它的线程不同的线程访问OOM对象,Outlook 2013将立即引发异常。在大多数情况下,Outlook迁移的较旧版本会工作,但在最不幸的时刻会失败。
上面的代码在辅助线程上创建了Outlook.Application对象的新实例。你可以这样做,但是所有的调用都将被编组到主要的Outlook线程中,因此使用辅助线程对你没有多大帮助。
唯一的解决方法是使用扩展MAPi(C ++或Delphi)或使用MAPI的封装器(例如Redemption)。
