例

次のコードサンプルは、動的クラスの外部でアンマネージ型メソッドを EmitCalli 呼び出すメソッドのコンテキストでの使用方法を示しています。

MethodBuilder^ myMthdBuilder = myTypeBuilder->DefineMethod( "MyMethod",
                               MethodAttributes::Public,
                               returnType, mthdParamTypes );

// We will assume that an external unmanaged type "LegacyNumber" has been loaded, and
// that it has a method "ToString" which returns a String.

MethodInfo^ unmanagedMthdMI = Type::GetType( "LegacyNumber" )->GetMethod( "ToString" );
ILGenerator^ myMthdIL = myMthdBuilder->GetILGenerator();

// Code to emit various IL opcodes here ...

// Load a reference to the specific Object instance onto the stack.

myMthdIL->Emit( OpCodes::Ldc_I4, addrOfLegacyNumberObject );
myMthdIL->Emit( OpCodes::Ldobj, Type::GetType( "LegacyNumber" ) );

// Make the call to the unmanaged type method, telling it that the method is
// the member of a specific instance, to expect a String
// as a return value, and that there are no explicit parameters.
myMthdIL->EmitCalli( OpCodes::Calli,
                     System::Runtime::InteropServices::CallingConvention::ThisCall,
                     String::typeid,
                     gcnew array<Type^>( 0 ) );

// More IL code emission here ...

MethodBuilder myMthdBuilder = myTypeBuilder.DefineMethod("MyMethod",
                  MethodAttributes.Public,
                  returnType, mthdParamTypes);
                            
// We will assume that an external unmanaged type "LegacyNumber" has been loaded, and
// that it has a method "ToString" which returns a string.

MethodInfo unmanagedMthdMI = Type.GetType("LegacyNumber").GetMethod("ToString");
ILGenerator myMthdIL = myMthdBuilder.GetILGenerator();

// Code to emit various IL opcodes here ...

// Load a reference to the specific object instance onto the stack.

myMthdIL.Emit(OpCodes.Ldc_I4, addrOfLegacyNumberObject);

// Make the call to the unmanaged type method, telling it that the method is
// the member of a specific instance, to expect a string

myMthdIL.EmitCalli(OpCodes.Calli,
           System.Runtime.InteropServices.CallingConvention.ThisCall,
               typeof(string),
           new Type[] {});

// More IL code emission here ...

    Dim myMthdBuilder As MethodBuilder = myTypeBuilder.DefineMethod("MyMethod", _
                    MethodAttributes.Public, _
                    returnType, mthdParamTypes)
  
    ' We will assume that an external unmanaged type "LegacyNumber" has been loaded, and
    ' that it has a method "ToString" which returns a string.

    Dim unmanagedMthdMI As MethodInfo = Type.GetType("LegacyNumber").GetMethod("ToString")
    Dim myMthdIL As ILGenerator = myMthdBuilder.GetILGenerator()
  
    ' Code to emit various IL opcodes here ...
    ' Load a reference to the specific object instance onto the stack.

    myMthdIL.Emit(OpCodes.Ldc_I4, addrOfLegacyNumberObject)
    myMthdIL.Emit(OpCodes.Ldobj, Type.GetType("LegacyNumber"))
  
    ' Make the call to the unmanaged type method, telling it that the method is
