Fehler Guss Zeichenfolge auf Dezimal

Question

ich diese beiden Fehler bekommen:

der String-Typ kann nicht konvertieren

auf dezimal:

(str1 = (Decimal) (num1/num3).ToString("0.00").Replace(".00", string.Empty);) 

und

(str2 = (Decimal) (num4/num5).ToString("0.00").Replace(".00", string.Empty);) 

Wie kann ich? repariere das?

einfach die Würfe zu Dezimal entfernen und es funktioniert wie erwartet:

Answer 2

Sie sind zu String Umwandlung und dann cast es zu einem string tatsächlich.

Like this Sie würden cast zuerst:

((Decimal) (num1/num3)).ToString()
