I would like to send a mail with variables. The first snippet is a raw HTML mailto text, the other one is my solution.
The problem is that then the body of the mail is no longer generated.
<a href="mailto:m.mustermann@domain.de?subject=Test%20Test%20Test%20Test&body=Test%20Test,%0D%0A%0D%0ATest%20Test%20Test%20Test.">Test</a> <a href="mailto:?subject=MessageCode: @ErrorCode %20&body=Test%20Test,%0D%0A%0D%0AURL: @navigationManager.Uri">Send Mail</a>
Everything in the mailto: has to be Url encoded. Especially the URL from navigationManager.
This works:
<a href="mailto:?subject=MessageCode%3A @ErrorCode Test&body=Test%20Test,%0D%0A%0D%0AURL%3A @MyUrl">Send Mail</a>
with
string MyUrl => System.Web.HttpUtility.UrlEncode(navigationManager.Uri);
Also note the %3A instead of :
When your @ErrorCode can have punctuation in it then give it the same treatment.
It is a good thing that space are allowed because %20@ErrorCode does not work.
