outlook 召回消息 c#

Question

我正在尝试使用 C# 构建用于在 Outlook 中召回消息的代码。我在 outlook 中有一个自定义选项卡并有按钮。我需要在点击按钮时构建一个代码（选择已发送邮件后），它必须调用 outlook 的召回邮件功能。

我知道撤回消息的限制。但是组织仍然希望继续这样做。如果有人有调用召回消息按钮的 c# 代码，请告诉我们。感谢和问候，

如何在 c# 中为 outlook 2010 编译以下代码，因为命令栏已贬值且具有 IRibbonExtensibility

 Option Explicit Sub Recall()   Dim SendItem As Object   Dim olItem As
 Outlook.MailItem   Dim olInsp As Outlook.Inspector

   '// Selected item in Sent Items folder   Set SendItem =
 ActiveExplorer.Selection.Item(1)

  If TypeName(SendItem) = "MailItem" Then
     Set olItem = SendItem
     Set olInsp = olItem.GetInspector
     '// Execute Recall command button
     With olInsp
       .Display
       .CommandBars.FindControl(, 2511).Execute
       .Close olDiscard
     End With

如果结束子则结束

/////我的代码如下所示

Outlook.MailItem MailItemRecall = (MailItem)selObject;
  if (MailItemRecall != null)
            {


                Outlook.Action recallaction = selObject.Actions.Add();
                recallaction.Name = "Recall This Message";
                recallaction.MessageClass = "IPM.Outlook.Recall";
                recallaction.ResponseStyle = OlActionResponseStyle.olSend;
                recallaction.CopyLike = OlActionCopyLike.olReplyFolder;
                recallaction.Execute(); 
}

我自己找到了答案。

 1: private void btnRecall_Click(object sender, RibbonControlEventArgs e)
    2:        {
    3:            Outlook.MailItem oldMailItem = GetMailItem(e);
    4:            Inspector inspect=  oldMailItem.GetInspector;
    5:            inspect.Display(false);
    6:            inspect.CommandBars.ExecuteMso("RecallThisMessage");           
    7:        }
    8:
    9:    private Microsoft.Office.Interop.Outlook.MailItem GetMailItem(RibbonControlEventArgs e)
    10:        {
    11:            // Check to see if a item is select in explorer or we are in inspector.
    12:            if (e.Control.Context is Microsoft.Office.Interop.Outlook.Inspector)
    13:            {
    14:                Microsoft.Office.Interop.Outlook.Inspector inspector = (Microsoft.Office.Interop.Outlook.Inspector)e.Control.Context;
    15:
    16:                if (inspector.CurrentItem is Microsoft.Office.Interop.Outlook.MailItem)
    17:                {
    18:                    return inspector.CurrentItem as Microsoft.Office.Interop.Outlook.MailItem;
    19:                }
    20:            }
    21:
    22:            if (e.Control.Context is Microsoft.Office.Interop.Outlook.Explorer)
    23:            {
    24:                Microsoft.Office.Interop.Outlook.Explorer explorer = (Microsoft.Office.Interop.Outlook.Explorer)e.Control.Context;
    25:
    26:                Microsoft.Office.Interop.Outlook.Selection selectedItems = explorer.Selection;
    27:                if (selectedItems.Count != 1)
    28:                {
    29:                    return null;
    30:                }
    31:
    32:                if (selectedItems[1] is Microsoft.Office.Interop.Outlook.MailItem)
    33:                {
    34:                    return selectedItems[1] as Microsoft.Office.Interop.Outlook.MailItem;
    35:                }
    36:            }
    37:
    38:            return null;
    39:        }
