Příklady
Následující příklad ukazuje, jak použít GetArrayMethod k získání MethodToken odpovídající metody, která vrací hodnotu pole.
// 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 );
// Complete the creation of type.
myTypeBuilder->CreateType();
// Define a dynamic module in "TempAssembly" assembly.

// Get the 'MethodInfo' object corresponding to 'Sort' method of 'Array' class.
MethodInfo myMethodInfo=myModuleBuilder.GetArrayMethod(
myArrayClass.GetType(),"Sort",CallingConventions.Standard,
null,parameterTypes);
// Get the token corresponding to 'Sort' method of 'Array' class.
MethodToken myMethodToken=myModuleBuilder.GetArrayMethodToken(
myArrayClass.GetType(),"Sort",CallingConventions.Standard,
null,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);
// Complete the creation of type.
myTypeBuilder.CreateType();

Poznámky
Tato metoda je podobná GetArrayMethodmetodě s tím rozdílem, že místo samotné metody vrací token metody pole.
