Int32.MinValue Feld
Wichtig
Einige Informationen beziehen sich auf Vorabversionen, die vor dem Release ggf. grundlegend überarbeitet werden. Microsoft übernimmt hinsichtlich der hier bereitgestellten Informationen keine Gewährleistungen, seien sie ausdrücklich oder konkludent.
Stellt den kleinstmöglichen Wert von Int32 dar. Dieses Feld ist konstant.
public: int MinValue = -2147483648;
public const int MinValue = -2147483648;
val mutable MinValue : int
Public Const MinValue As Integer = -2147483648
Value = -2147483648
Im folgenden Beispiel wird die MinValue -Eigenschaft verwendet, um bei der OverflowException Konvertierung in einen Int32 Wert zu verhindern.
