Örnekler

Aşağıdaki kod örneği, yöntem çağrısının SetMarshal sonuçlarını farklı bir tür olarak sıralamak için yönteminin bağlamsal kullanımını gösterir.

array<Type^>^ temp0 = { String::typeid };
MethodBuilder^ myMethod = myDynamicType->DefineMethod( "MyMethodReturnsMarshal",
                          MethodAttributes::Public,
                          UInt32::typeid,
                          temp0 );

// We want the return value of our dynamic method to be marshalled as
// an 64-bit (8-Byte) signed integer, instead of the default 32-bit
// unsigned int as specified above. The UnmanagedMarshal class can perform
// the type conversion.

UnmanagedMarshal^ marshalMeAsI8 = UnmanagedMarshal::DefineUnmanagedMarshal(
                                  System::Runtime::InteropServices::UnmanagedType::I8 );

myMethod->SetMarshal( marshalMeAsI8 );

MethodBuilder myMethod = myDynamicType.DefineMethod("MyMethodReturnsMarshal",
                    MethodAttributes.Public,
                    typeof(uint),
                    new Type[] { typeof(string) });

// We want the return value of our dynamic method to be marshalled as
// an 64-bit (8-byte) signed integer, instead of the default 32-bit
// unsigned int as specified above. The UnmanagedMarshal class can perform
// the type conversion.

UnmanagedMarshal marshalMeAsI8 = UnmanagedMarshal.DefineUnmanagedMarshal(
                     System.Runtime.InteropServices.UnmanagedType.I8);	

myMethod.SetMarshal(marshalMeAsI8);
Dim myMethod As MethodBuilder = myDynamicType.DefineMethod("MyMethodReturnsMarshal", _
              MethodAttributes.Public, GetType(System.UInt32), _
              New Type() {GetType(String)}) 

' We want the return value of our dynamic method to be marshalled as 
' an 64-bit (8-byte) signed integer, instead of the default 32-bit
' unsigned int as specified above. The UnmanagedMarshal class can perform

Dim marshalMeAsI8 As UnmanagedMarshal = UnmanagedMarshal.DefineUnmanagedMarshal( _
                    System.Runtime.InteropServices.UnmanagedType.I8)

myMethod.SetMarshal(marshalMeAsI8)
