Kommentarer

Privata fält är endast tillgängliga från medlemsfunktioner.

Egenskapen IsPrivate anges när FieldAttributes.Private attributet har angetts.

IsPrivate Hämta egenskapen genom att först hämta klassen Type. TypeFrån hämtar du FieldInfo. Hämta egenskapen från FieldInfoIsPrivate . Om du vill komma åt ett icke-offentligt fält anger du BindingFlags till NonPublic, och antingen Static eller Instance i GetField -metoden.
