Link to Open New Email Message in Default E-mail Handler in WPF Application
提问by user3342256
My goal is basic: Have a label/texblock what-have-you on a WPF form that is stylized to look like a link. When clicked, the control should open a new e-mail composition window in the user's default e-mail app. The code to actually open the new e-mail window seems trivial:
我的目标是基本的：在 WPF 表单上有一个标签/texblock what-have-you，它的样式看起来像一个链接。单击时，控件应在用户的默认电子邮件应用程序中打开一个新的电子邮件撰写窗口。实际打开新电子邮件窗口的代码似乎微不足道：
Process.Start("mailto:[email protected]?subject=SubjectExample&body=BodyExample ");
However I'm having trouble with two pieces:
但是我在两件事情上遇到了麻烦：
- Binding the "new message open" action to a label click event.
- Stylizing the label so that it looks exactly like a default WPF hyperlink.
- 将“新消息打开”操作绑定到标签点击事件。
- 样式化标签，使其看起来与默认的 WPF 超链接完全相同。

If you want the style to be like a hyperlink, why not just use one directly?
如果你想让样式像一个超链接，为什么不直接使用一个呢？
<TextBlock>
<Hyperlink NavigateUri="mailto:[email protected]?subject=SubjectExample&body=BodyExample" RequestNavigate="OnNavigate">
Click here
</Hyperlink>
</TextBlock>
Then add:
然后加：
private void OnNavigate(object sender, RequestNavigateEventArgs e)
{
Process.Start(e.Uri.AbsoluteUri);
e.Handled = true;
}

You can do this entirely in XAML Use Expression interactions to call the link mentioned above
您可以完全在 XAML 中使用表达式交互来调用上面提到的链接
