从Outlook电子邮件获取身体[Drag'n'Drop] [英] Get body from Outlook email [Drag’n’Drop]

问题描述

我正在和WPF一起工作，我正在努力做一个drag'n'drop文本框。

在这个文本框中，我想得到一个从outlook拖动的电子邮件的正文。

代码可以工作，但是我想我需要一些东西来重置ActiveExplorer，因为它只显示我拖到文本框中的最后一个新电子邮件。

示例：

拖动电子邮件1 - >文本框 - 显示电子邮件1

拖动电子邮件2 - >文本框 - 显示电子邮件2

拖动电子邮件1 - >文本框 - 显示电子邮件2和电子邮件1将不会显示，因为它已经存在于ActiveExplorer中，它将显示电子邮件2。

希望我的问题对你来说有点清楚。 。
提前感谢！

XAML代码：

 code>< TextBox 
 Name =myTextbox
 AllowDrop =True
 PreviewDragEnter =email_DragEnter
 PreviewDrop =email_Drop/> 
  

XAML代码：

  private void email_DragEnter（object sender，DragEventArgs e）
 {
 e.Effect = DragDropEffects.Copy; 
} 
 
 private void email_Drop（object sender，DragEventArgs e）
 {
 Outlook.ApplicationClass oApp = new Outlook.ApplicationClass（）; 
 Outlook.Explorer oExplorer = oApp.ActiveExplorer（）; 
 Outlook.Selection oSelection = oExplorer.Selection; 
 
 foreach（oSelection中的对象项）
 {
 Outlook.MailItem mi =（Outlook.MailItem）项; 
 myTextbox.Text = mi.Body.ToString（）; 
} 
} 
  

解决方案

将如下的DragDrop事件中的 oApp 的声明移动到其中，并按预期方式工作。

 code> void Startup（）
 {
 _Outlook = new Outlook.Application（）; 
} 
 
 Outlook.Application _Outlook = null; 
 
 private void Form1_DragEnter（object sender，DragEventArgs e）
 {
 e.Effect = DragDropEffects.Copy; 
} 
 
 private void Form1_DragDrop（object sender，DragEventArgs e）
 {
 richTextBox1.Text =; 
 Outlook.Explorer oExplorer = _Outlook.ActiveExplorer（）; 
 Outlook.Selection oSelection = oExplorer.Selection; 
 
 foreach（oSelection中的对象项）
 {
 Outlook.MailItem mi =（Outlook.MailItem）项; 
 richTextBox1.AppendText（mi.Body.ToString（）+\\\
 ------------------------------ ---------- \\\
）; 
} 
} 
  

--------编辑 - ------

OR由于此循环，您是否可以仅显示最后一个项目？

  foreach（oSelection中的对象项）
 {
 Outlook.MailItem mi =（Outlook.MailItem）项; 
 myTextbox.Text = mi.Body.ToString（）; //< ---仅最后的项目文本
} 
  

I’m working with WPF and I’m trying to make a drag’n’drop textbox.
In this textbox I want to get the body of an email which I drag from outlook.
The code works but I think I need something to "reset" the ActiveExplorer cause now it only shows the last "NEW" email which I drag into the textbox.

Example:

Drag email 1 -> Textbox - Shows email 1

Drag email 2 -> Textbox - Shows email 2

Drag email 1 -> Textbox - Shows email 2 and email 1 will not be displayed because it already exists in the ActiveExplorer and it will show email 2.

Hope my question is a bit clear to you..
Thanks in advance!

XAML code:

    <TextBox 
    Name="myTextbox"  
    AllowDrop="True" 
    PreviewDragEnter="email_DragEnter"
    PreviewDrop="email_Drop" />

XAML code behind:

    private void email_DragEnter(object sender, DragEventArgs e)
    {
        e.Effect = DragDropEffects.Copy;
    }

    private void email_Drop(object sender, DragEventArgs e)
    {
        Outlook.ApplicationClass oApp = new Outlook.ApplicationClass();
        Outlook.Explorer oExplorer = oApp.ActiveExplorer();
        Outlook.Selection oSelection = oExplorer.Selection;

        foreach (object item in oSelection)
        {
            Outlook.MailItem mi = (Outlook.MailItem)item;
            myTextbox.Text = mi.Body.ToString();
        }
    }

解决方案

I moved the declaration of oApp out of DragDrop event as below, and it works as expected.

void Startup()
{
    _Outlook = new Outlook.Application();
}

Outlook.Application _Outlook = null;

private void Form1_DragEnter(object sender, DragEventArgs e)
{
    e.Effect = DragDropEffects.Copy;
}

private void Form1_DragDrop(object sender, DragEventArgs e)
{
    richTextBox1.Text = "";
    Outlook.Explorer oExplorer = _Outlook.ActiveExplorer();
    Outlook.Selection oSelection = oExplorer.Selection;

    foreach (object item in oSelection)
    {
        Outlook.MailItem mi = (Outlook.MailItem)item;
        richTextBox1.AppendText(mi.Body.ToString() + "\n----------------------------------------\n");
    }
}

--------EDIT--------

OR Is it possible that you display only the last item because of this loop?

foreach (object item in oSelection)
{
    Outlook.MailItem mi = (Outlook.MailItem)item;
    myTextbox.Text = mi.Body.ToString(); //<--- Only last items text
}
