範例

下列範例示範如何使用 GetArrayMethod 來取得 MethodInfo 對應至傳回陣列值的方法。

// 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 );

備註

GetArrayMethod 當您的型別陣列尚未完成定義且您想要存取 上 Array定義的方法時,會很有用。 例如,您可以定義型別,並想要定義接受型別陣列做為參數的方法。 若要存取陣列的專案,您必須呼叫 類別的方法 Array
