Exemplos
O exemplo a seguir determina a página de código do Windows que melhor corresponde a cada codificação.
using namespace System;
using namespace System::Text;
int main()
{
// Print the header.
Console::Write( "CodePage identifier and name " );
Console::WriteLine( "WindowsCodePage" );
// For every encoding, get the Windows code page for it.
System::Collections::IEnumerator^ myEnum = Encoding::GetEncodings()->GetEnumerator();
while ( myEnum->MoveNext() )
{
EncodingInfo ^ ei = safe_cast<EncodingInfo ^>(myEnum->Current);
Encoding^ e = ei->GetEncoding();
Console::Write( "{0,-6} {1,-25} ", ei->CodePage, ei->Name );
Console::Write( "{0,-6} ", e->WindowsCodePage );
// Mark the ones that are different.
if ( ei->CodePage != e->WindowsCodePage )
Console::Write( "*" );
Console::WriteLine();
