Exemples

L’exemple suivant montre comment utiliser GetArrayMethod pour obtenir le MethodInfo correspondant à une méthode qui retourne une valeur de tableau.The following example demonstrates how to use GetArrayMethod to obtain the MethodInfo corresponding to a method that returns an array value.

// Define a dynamic module in "TempAssembly" assembly.
ModuleBuilder^ myModuleBuilder = myAssemblyBuilder->
   DefineDynamicModule( "TempModule" );

// Define a runtime class with specified name and attributes.
TypeBuilder^ myTypeBuilder = myModuleBuilder->DefineType(
   "TempClass", TypeAttributes::Public );
array<Type^>^ paramArray = { Array::typeid };
// Add 'SortArray' method to the class, with the given signature.
MethodBuilder^ myMethod = myTypeBuilder->DefineMethod( "SortArray",
   MethodAttributes::Public, Array::typeid, paramArray );

array<Type^>^ myArrayClass = gcnew array<Type^>( 1 );
array<Type^>^ parameterTypes = { Array::typeid };
// Get the 'MethodInfo' object corresponding to 'Sort' method of 'Array' class.
MethodInfo^ myMethodInfo = myModuleBuilder->GetArrayMethod(
   myArrayClass->GetType(), "Sort", CallingConventions::Standard,
   nullptr, parameterTypes );

// Get the token corresponding to 'Sort' method of 'Array' class.
MethodToken myMethodToken = myModuleBuilder->GetArrayMethodToken(
   myArrayClass->GetType(), "Sort", CallingConventions::Standard,
   nullptr, parameterTypes );
Console::WriteLine( "Token used by module to identify the 'Sort' method"
   + " of 'Array' class is : {0:x} ", myMethodToken.Token );

ILGenerator^ methodIL = myMethod->GetILGenerator();
methodIL->Emit( OpCodes::Ldarg_1 );
methodIL->Emit( OpCodes::Call, myMethodInfo );
methodIL->Emit( OpCodes::Ldarg_1 );
methodIL->Emit( OpCodes::Ret );

Remarques

GetArrayMethod est utile quand vous avez un tableau d’un type dont la définition n’a pas été effectuée et que vous souhaitez accéder aux méthodes définies sur Array .GetArrayMethod is useful when you have an array of a type whose definition has not been completed and you want to access methods defined on Array. Par exemple, vous pouvez définir un type et souhaiter définir une méthode qui prend un tableau du type comme paramètre.For example, you might define a type and want to define a method that takes an array of the type as a parameter. Pour accéder aux éléments du tableau, vous devez appeler des méthodes de la Array classe.In order to access the elements of the array, you will need to call methods of the Array class.
