C＃启动一个新的MailTo进程和HTML URL编码

我为Process类创建了一个新的MailTo扩展方法，它只是用一个包含所需mailto参数的新ProcessStartinfo填充Process。 我已经创建了一个名为FormatMailToArgument的方法（最后在右边），它将控制字符转换为它们的Url编码等价物并测试了它并且它可以工作但是有更好的方法吗？

Answer 1

如果您的意思是有更有效的方法来转义您的电子邮件地址，那么您可以使用System.Uri类。

 string escapedAddress = Uri.EscapeUriString("mailto:joe blogg's\r\[e-mail]"); Console.WriteLine(escapedAddress); 

输出：

 mailto:joe%20blogg'[e-mail] 

你会注意到我的例子中单引号字符没有被转义，但这是因为它不需要在电子邮件地址中。

就您使用的一般方法而言，我不明白为什么要向Process类添加扩展方法。 发送电子邮件并让所有地址都逃脱。 附件，服务器身份validation等等。照顾为什么不只是使用System.Net.Mail类？

如此官方链接中所述， EscapeUriString方法假定stringToEscape参数中没有转义序列。

这个方法非常适合转义Uris，但要小心，因为目标字符串是一个mailto:行，可以包含许多参数（不仅是主题，正文，…），显然每个参数都有一些转义字符…就像＆和？ 。

因此，在我的Windows Store应用程序测试中，文本取自@anon注释，该字符串不会仅使用Uri.EscapeUriString()方法完全转义，因为它包含转义序列＆ 。

你将需要一个额外的手动转义来将整个字符串作为参数传递到mailto: Uri：

 Uri.EscapeUriString(stringToEscape).Replace("&", "%26");
