c# - Unable to create a new mail with multiple recipients with mailto uri -
i using creating windows 8.1 store app in winrt.
i unable create new mail multiple recipients mailto uri separating each email either comma or semi colon, both gives me same error.
invalid uri: hostname not parsed. the mailto strings looks this
"mailto:username@mail.com,username2@mail.com" "mailto:username@mail.com,username2@mail.com," "mailto:username@mail.com, username2@mail.com" "mailto:username@mail.com;username2@mail.com" "mailto:username@mail.com;username2@mail.com;" "mailto:username@mail.com; username2@mail.com" i have tried these variants give me same error when newing uri, this.
var uri = new uri(string.format("mailto:{0}", mails)); i have no idea doing wrong, or in case not implemented why wouldn't be?
i created few unit tests see if variations work, no..

according mailto:protocol @ msdn should able use mailto protocol multiple recipients.

there hack, using hyperlinkbutton (sorry, dirty hack) :
- load
hyperlinkbuttonusingxamlreader, - retrieve
automationpeer, launch click
var uristring = "mailto:username@mail.com,username2@mail.com"; string xamlstring = "<hyperlinkbutton " + "xmlns=\"http://schemas.microsoft.com/winfx/2006/xaml/presentation\" " + "navigateuri=\"" + uristring + "\"/>"; var c = (hyperlinkbutton)xamlreader.load(xamlstring); new hyperlinkbuttonautomationpeer(c).invoke();
