Beispiele
Im folgenden Beispiel werden die IsContextfulIsMarshalByRefEigenschaften und Eigenschaften IsPrimitive der Type Klasse veranschaulicht. Er überprüft, ob der angegebene Typ im Kontext gehostet werden kann, ob er anhand eines Verweises gemarstet werden kann und ob es sich bei dem Typ um einen primitiven Datentyp handelt.

Hinweise
Die Grundtypen sind Boolean, , Byte, SByte, Int16UInt16Int32UInt32, Int64, UInt64IntPtrUIntPtr, , Char, , und . DoubleSingle
Wenn der aktuelle Typ einen generischen Typ oder einen Typparameter in der Definition eines generischen Typs oder einer generischen Type Methode darstellt, gibt diese Eigenschaft immer zurück false.
