c# - new MailAddress() Exits out of method -

i have weird issue can't wrap head around. here code:

[httpget] [allowanonymous] public actionresult sendemail() {     sendregisteremail("test", "testagain", "lasttest");     return view("index"); }  public async task<bool> sendregisteremail(string subject, string message, string to) {     var email = new email();     var mailaddress = new mailaddress(to);     email.subject = subject;     email.body = message;     var mailaddresscollection = new mailaddresscollection();     mailaddresscollection.add(mailaddress);     email.to = (mailaddresscollection);      return await send(email); } 

now prove problem broke down code single lines can see on line breaks. here found:

when debug , step sendregisteremail method, line says var mailaddress = new mailaddress(to); gets run , exits out function , runs line return view("index"); , page loads up. weird thing added logging method on send @ end , logging never gets hit. put breakpoint on send , never got hit. if creation of email crashed, decided exit out caller function , continued code.

i don't have faintest clue why.

sendregisteremail method asynchronous, you're not awaiting it.

currently, start fire-and-forget operation , return view instruction executed while you're creating new mailaddress instance. throws formatexception can't catch because exception thrown in thread.

update action method

public async task <actionresult> sendemail() {     await sendregisteremail("test", "testagain", "lasttest");     return view("index"); } 

also awaiting before return not needed, can change

public task<bool> sendregisteremail(string subject, string message, string to) {     var email = new email();     // ...      return send(email); } 

but that's not related problem you've got.
