이 생성자의 매개 변수를 반환합니다.

public:
 override cli::array <System::Reflection::ParameterInfo ^> ^ GetParameters();

public override System.Reflection.ParameterInfo[] GetParameters ();

override this.GetParameters : unit -> System.Reflection.ParameterInfo[]

Public Overrides Function GetParameters () As ParameterInfo()

반환

ParameterInfo[]

이 생성자의 매개 변수를 나타내는 배열입니다.

예외

InvalidOperationException

.NET Framework 버전 1.0 및 1.1에서CreateType() 이 이 생성자의 형식에 호출되지 않았습니다.

NotSupportedException

.NET Framework 버전 2.0에서CreateType() 이 이 생성자의 형식에 호출되지 않았습니다.
