Hinweise

Um den ParameterAttributes Wert zu erhalten, erhalten Sie Typezuerst die.To get the ParameterAttributes value, first get the Type. Im können Sie das ParameterInfo Array erhalten. TypeFrom the Type, get the ParameterInfo array. Der ParameterAttributes Wert liegt innerhalb des Arrays.The ParameterAttributes value is within the array.

Diese Enumeratorwerte sind von optionalen Metadaten abhängig.These enumerator values are dependent on optional metadata. Nicht alle Attribute sind für alle Compiler verfügbar.Not all attributes are available from all compilers. Sehen Sie sich die entsprechenden Compileranweisungen an, um zu bestimmen, welche aufgelisteten Werte verfügbar sind.See the appropriate compiler instructions to determine which enumerated values are available.
