Exemplos

O exemplo seguinte utiliza o fornecedor de código C# ou Visual Basic para compilar um ficheiro fonte. O exemplo verifica a extensão do ficheiro de entrada e utiliza o correspondente CSharpCodeProvider or VBCodeProvider for compilation. O ficheiro de entrada é compilado num ficheiro executável, e quaisquer erros de compilação são exibidos na consola.
