LogicalMethodInfo.Invoke メソッド
現在の LogicalMethodInfo が表すメソッドを呼び出します。
Public Function Invoke( _
ByVal target As Object, _ ByVal values() As Object _) As Object()
[C#]
public object[] Invoke(objecttarget,object[] values);
[C++]
public: Object* Invoke(Object* target,Object* values __gc[]) __gc[];
[JScript]
public function Invoke(
target : Object,values : Object[]) : Object[];
パラメータ
- target
メソッドの呼び出し元となる Object のインスタンス。 - values
呼び出すメソッドの引数リスト。これは、メソッドのパラメータと同じ数、順序、型のオブジェクトの配列です。メソッドにパラメータが必要ない場合、 values パラメータは null 参照 (Visual Basic では Nothing) です。
戻り値
呼び出されたメソッドの戻り値と out パラメータを表す Object 型の配列。
例外
| 例外の種類 | 条件 |
|---|---|
| TargetException | target パラメータが null 参照 (Visual Basic では Nothing) です。 |
| ArgumentException | values パラメータの数、型、およびパラメータの順序が、呼び出されたメソッドのシグネチャと一致しません。 |
| MemberAccessException | 呼び出し元に、このメソッドを呼び出すためのアクセス許可がありません。 |
| TargetInvocationException | 呼び出されたメソッドが例外をスローしました。 |
