ModuleBuilder.GetArrayMethod メソッド

定義

配列クラスの名前付きメソッドを返します。

public:
 System::Reflection::MethodInfo ^ GetArrayMethod(Type ^ arrayClass, System::String ^ methodName, System::Reflection::CallingConventions callingConvention, Type ^ returnType, cli::array <Type ^> ^ parameterTypes);
public System.Reflection.MethodInfo GetArrayMethod (Type arrayClass, string methodName, System.Reflection.CallingConventions callingConvention, Type? returnType, Type[]? parameterTypes);
public System.Reflection.MethodInfo GetArrayMethod (Type arrayClass, string methodName, System.Reflection.CallingConventions callingConvention, Type returnType, Type[] parameterTypes);
member this.GetArrayMethod : Type * string * System.Reflection.CallingConventions * Type * Type[] -> System.Reflection.MethodInfo
Public Function GetArrayMethod (arrayClass As Type, methodName As String, callingConvention As CallingConventions, returnType As Type, parameterTypes As Type()) As MethodInfo

パラメーター

arrayClass
Type

配列クラス。

methodName
String

配列クラスのメソッドの名前。

callingConvention
CallingConventions

メソッドの呼び出し規則。

returnType
Type

メソッドの戻り値の型。

parameterTypes
Type[]

メソッドのパラメーター型。

戻り値

配列クラスの名前付きメソッド。

例外

arrayClass が配列ではありません。

arrayClass または methodNamenull です。

次の例では、 を使用 GetArrayMethod して、配列値を MethodInfo 返すメソッドに対応する を取得する方法を示します。

注釈

GetArrayMethod は、定義が完了していない型の配列があり、 で定義されているメソッドにアクセスする場合に Array便利です。 たとえば、型を定義し、その型の配列をパラメーターとして受け取るメソッドを定義できます。 配列の要素にアクセスするには、 クラスのメソッド Array を呼び出す必要があります。
