C# Visual Studio 2008 - Design-Zeit, Fehler in der Windows Forms-Designer
Wie beheben Sie die Design-Zeit-Fehler in der Windows Forms-Designer?
Wenn ich auf MyMainForm.cs[Design] Seite, um die WinForms bekomme ich die folgende Fehlermeldung:
To prevent possible data loss before loading the designer, the following errors must be resolved:
The class name '?' is not a valid identifier for this language.

Schließen der Lösung, re-öffnen und öffnen der form. Meiner Erfahrung nach, die Fehler Weggehen kann, nur zu re-Oberfläche später wieder.
Wenn die Fehler nicht Weggehen, dann nach

und
http://social.msdn.microsoft.com/Forums/en/winformsdesigner/thread/f2c1a027-3e49-4f7f-a4c2-c91a8fde25fc
haben Sie eventuell zu viele schließende Klammern irgendwo.
Ich hatte diesen Fehler, und es war, weil ich hatte eine ungültige Variablennamen (beginnend mit einer Zahl). Hoffe, dies hilft jemand anderes, wie kann es zu diesem Problem.
Schließen Sie die Lösung,reinigen Sie die Lösung und die Projektmappe neu erstellen und Ihnen proble gehen,Haupt-Formular-designer wird sichtbar...
... und wenn noch da ist..geh einfach n überprüfen Sie die Letzte änderung u fertig im code..dort haben Sie eventuell zu viele schließende Klammern.
hoffe, dies für Sie zu arbeiten..
In meinem Fall habe ich eine text-Datei, und die Standard-build-Aktion war zufrieden. Wenn ich das geändert, zu bauen Aktion keine dann der Fehler "The class name '?' ist kein Gültiger Bezeichner für diese Sprache.", ging Sie Fort.
Ist die übliche Vorgehensweise ist, einen Blick für Fehler in den Design-code, aber ich entdeckte, dass das ist wenig hilfreich, weil alles richtig ist (der Designer erzeugt guten code, und ich hatte noch nicht berührte).
Des Fehlers stellte sich heraus zu sein, in meinem eigenen code (einen Versuch war fehlende geschweifte Klammern). Es ist interessant, dass ein Fehler in meinem code, brach der Designer. Ich erwartete es, um unabhängig zu sein (zu einem gewissen Grad).
