Möjliga användningsscenarier
Om du tilldelar ogiltigt anpassat nummerformat tillStyle.Customegendom så kommer Aspose.Cells inte att ge något undantag. Men om du vill att Aspose.Cells ska kontrollera om det tilldelade anpassade nummerformatet är giltigt eller inte, ställ inWorkbook.Settings.CheckCustomNumberFormat egendom tillSann.
Kontrollera Custom Number Format när du ställer in Style.Custom-egenskapen
Följande exempelkod tilldelar ett ogiltigt anpassat nummerformat tillStyle.Custom fast egendom. Eftersom vi redan har sattWorkbook.Settings.CheckCustomNumberFormat egendom tillSann , därför kommer API att kasta CellsException t.exOgiltigt nummerformat.
