Exempel

Följande kodexempel är ett webbformulär som fyller i en DataGrid med information om dokumenten i Documents egenskapen tillsammans med de referenser som finns i varje dokument under IDENTIFIERING av XML-webbtjänster. Metoden PopulateGrid fyller DataGrid med resultatet från ett Discover anrop följt av ett anrop till ResolveAll.

Kommentarer

Metoden Discover förväntar sig att den angivna URL:en är ett identifieringsdokument. Om URL:en refererar till en tjänstbeskrivning eller ett XML-schema genereras ett undantag. Om du vill identifiera ett XML-schema eller en tjänstbeskrivning anropar du DiscoverAny metoden.

Om den angivna URL:en pekar på ett giltigt identifieringsdokument läggs identifieringsdokumentet på den angivna URL:en till i Documents samlingen och References . Dessutom läggs referenser i identifieringsdokumentet till i References samlingen, men verifieras inte för att peka på giltiga identifieringsdokument. Om du vill verifiera referenserna pekar du på giltiga identifieringsdokument för att anropa ResolveAll metoderna eller ResolveOneLevel .
