示例

下面的代码示例枚举计算机上的语言提供程序，并显示每个语言提供程序的配置和编译器设置。 此代码示例是为 CompilerInfo 类提供的一个更大示例的一部分。

array<CompilerInfo^>^allCompilerInfo = CodeDomProvider::GetAllCompilerInfo();
for ( int i = 0; i < allCompilerInfo->Length; i++ )
{
   String^ defaultLanguage;
   String^ defaultExtension;
   CompilerInfo^ info = allCompilerInfo[ i ];
   CodeDomProvider^ provider = nullptr;
   if ( info )
      provider = info->CreateProvider();

   if ( provider )
   {
      // Display information about this configured provider.
      Console::WriteLine( "Language provider:  {0}", provider->ToString() );
      Console::WriteLine();
      Console::WriteLine( "  Supported file extension(s):" );
      array<String^>^extensions = info->GetExtensions();
      for ( int i = 0; i < extensions->Length; i++ )
          Console::WriteLine( "    {0}", extensions[ i ] );

      defaultExtension = provider->FileExtension;
      if (  !defaultExtension->StartsWith( "." ) )
          defaultExtension = String::Concat( ".", defaultExtension );

      Console::WriteLine( "  Default file extension:  {0}\n", defaultExtension );
      Console::WriteLine( "  Supported language(s):" );
      array<String^>^languages = info->GetLanguages();
      for ( int i = 0; i < languages->Length; i++ )
          Console::WriteLine( "    {0}", languages[ i ] );

      defaultLanguage = CodeDomProvider::GetLanguageFromExtension( defaultExtension );

      Console::WriteLine();
      
      // Get the compiler settings for this provider.
      CompilerParameters^ langCompilerConfig = info->CreateDefaultCompilerParameters();
      if ( langCompilerConfig )
