ModuleBuilder.GetArrayMethod Metode

Definisi

Mengembalikan metode bernama pada kelas array.

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

Parameter

arrayClass
Type

Kelas array.

methodName
String

Nama metode pada kelas array.

callingConvention
CallingConventions

Konvensi panggilan metode.

returnType
Type

Jenis pengembalian metode .

parameterTypes
Type[]

Jenis parameter metode.

Mengembalikan

Metode bernama pada kelas array.

Pengecualian

arrayClass bukan array.

arrayClass atau methodName adalah null.

Contoh

Contoh berikut menunjukkan cara menggunakan GetArrayMethod untuk mendapatkan MethodInfo yang sesuai dengan metode yang mengembalikan nilai array.

// 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.
ModuleBuilder myModuleBuilder = myAssemblyBuilder.
                              DefineDynamicModule("TempModule");
// Define a runtime class with specified name and attributes.
TypeBuilder myTypeBuilder = myModuleBuilder.DefineType
                           ("TempClass",TypeAttributes.Public);
Type[] paramArray = {typeof(Array)};
// Add 'SortArray' method to the class, with the given signature.
MethodBuilder myMethod = myTypeBuilder.DefineMethod("SortArray",
                          MethodAttributes.Public,typeof(Array),paramArray);

Type[] myArrayClass = new Type[1];
Type[] parameterTypes = {typeof(Array)};
// 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();
' Define a dynamic module in "TempAssembly" assembly.
Dim myModuleBuilder As ModuleBuilder = myAssemblyBuilder.DefineDynamicModule("TempModule")
' Define a runtime class with specified name and attributes.
Dim myTypeBuilder As TypeBuilder = _
            myModuleBuilder.DefineType("TempClass", TypeAttributes.Public)

Dim myMethod As MethodBuilder = _
   myTypeBuilder.DefineMethod("SortArray", MethodAttributes.Public, _
   GetType(Array), myParamArray)

Dim myArrayClass(0) As Type
Dim parameterTypes() As Type = New Type() {GetType(Array)}
' Get the 'MethodInfo' object corresponding to 'Sort' method of 'Array' class.

   myModuleBuilder.GetArrayMethod(myArrayClass.GetType(), "Sort", _
   CallingConventions.Standard, Nothing, parameterTypes)

Keterangan

GetArrayMethod berguna ketika Anda memiliki array jenis yang definisinya belum selesai dan Anda ingin mengakses metode yang ditentukan pada Array. Misalnya, Anda dapat menentukan jenis dan ingin menentukan metode yang mengambil array dari jenis sebagai parameter. Untuk mengakses elemen array, Anda harus memanggil metode Array kelas .
