我为Process类创建了一个新的MailTo扩展方法，该方法只使用包含所需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有效但是有更好的方法吗？

答案 0 :(得分：8)
如果您的意思是有更有效的方式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\n@mail.com");
Console.WriteLine(escapedAddress);
输出：
mailto:joe%20blogg's%0D%0A@mail.com
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，服务器身份验证等。注意为什么不只是使用System.Net.Mail类？

如this official link中所述，EscapeUriString方法假定stringToEscape参数中没有转义序列。
此方法非常适合转义Uris，但要小心，因为目标字符串是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...比如＆amp; 和？。
因此，在我的Windows Store应用程序测试中，文本取自@anon注释，该字符串不会使用 Uri.EscapeUriString()方法完全转义，因为它包含转义序列< EM>＆安培;
您需要额外的手动转义才能将整个字符串作为mailto: Uri中的参数传递：
Uri.EscapeUriString(stringToEscape).Replace("&", "%26");
