[Original] use of idialogservice instead of dialogmessage in mvvmlight

In the new version of mvvmlight, dialogmessage is marked as obsolete and must be replaced by idialogservice. The specific usage of idialogservice is as follows:

First, implement idialogservice in the main form:

Public partial class mainwindow: window, idialogservice

Public System. Threading. Tasks. Task showerror (Exception error, String title, string buttontext, Action afterhidecallback) {Throw new notimplementedexception ();}

Public System. threading. tasks. task showerror (string message, String title, string buttontext, Action afterhidecallback) {Throw new notimplementedexception ();} public system. threading. tasks. task <bool> showmessage (string message, String title, string buttonconfirmtext, string buttoncanceltext, Action <bool> afterhidecallback) {Throw new notimplementedexception ();} public system. threading. tasks. task showmessage (string message, String title, string buttontext, Action afterhidecallback) {Throw new notimplementedexception ();} public system. threading. tasks. task showmessage (string message, String title) {// throw new notimplementedexception (); MessageBox. show (message, title); return NULL;} public system. threading. tasks. task showmessagebox (string message, String title) {// throw new notimplementedexception (); MessageBox. show (message, title); return NULL ;}
Then register idialogservice: Public idialogservice dialogservice {get {return servicelocator. current. getinstance <idialogservice> () ;}} is called dialogservice. showmessagebox ("enter a name! "," Prompt ");
