VSTO Outlook:获取选定的附件

本文关键字：Outlook 获取 VSTO | 更新日期: 2023-09-27 18:02:02

我正在尝试对outlook 2010中选定的附件执行操作。我在VS2012中创建了一个Outlook VSTO项目。

这是用于在附件ribbon上添加按钮的XML:

<?xml version="1.0" encoding="UTF-8"?>
<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui" onLoad="Ribbon_Load">
  <ribbon>
    <contextualTabs>
      <tabSet idMso="TabSetAttachments">
        <tab idMso="TabAttachments">
          <group label="MyGroup" id="MyAttachmentGroup">
            <button id="AttachButton"
                size="large"
                label="Do something"
                imageMso="HappyFace"
                onAction="DoSomething" />
          </group>
        </tab>
      </tabSet>
    </contextualTabs>
  </ribbon>
</customUI>

这是ThisAddIn.cs

中的代码
protected override Microsoft.Office.Core.IRibbonExtensibility CreateRibbonExtensibilityObject()
{
    return new ProcessAttachment(this);
}

这是ProcessAttachment类:

[ComVisible(true)]
public class ProcessAttachment : Office.IRibbonExtensibility
{
    private Office.IRibbonUI ribbon;
    private ThisAddIn plugin;
    public ProcessAttachment(ThisAddIn plugin)
    {
        this.plugin = plugin;
    }
    public void Ribbon_Load(Office.IRibbonUI ribbonUI)
    {
        this.ribbon = ribbonUI;
    }
    public void DoSomething(Office.IRibbonControl control)
    {
        var explorer = plugin.Application.ActiveExplorer();
        var selection = explorer.Selection;
        if (selection.Count > 0)   
        {
            object selectedItem = selection[1];
            var mailItem = selectedItem as Outlook.MailItem;
            //How to get selected attachment?
        }
    }
}

我如何在这里获得选中的附件?

VSTO Outlook:获取选定的附件

我是这样解决的:(这段代码只是一个例子，需要改进)

public void DoSomething(Office.IRibbonControl control)
{
    var window = plugin.Application.ActiveWindow();
    var attachsel = window.AttachmentSelection();
    int? index = null;
    if (attachsel.count > 0)
    {
        var attachment = attachsel[1];
        index = attachment.Index;
    }
    var explorer = plugin.Application.ActiveExplorer();
    var selection = explorer.Selection;
    if ((selection.Count > 0) && (index != null))   
    {
        object selectedItem = selection[1];
        var mailItem = selectedItem as Outlook.MailItem;
        foreach (Outlook.Attachment attach in mailItem.Attachments)
        {
            if (attach.Index == index)
            {
                attach.SaveAsFile(Path.Combine(@"c:'temp'", attach.FileName));
            }
        }
    }
}

使用上下文ie。从控制。上下文是AttachmentSelection 

AttachmentSelection ats = (AttachmentSelection)control.Context;
ats[1] <- your selected attachment
