Il programma di esempio seguente può generare e compilare il codice sorgente in base a un modello CodeDOM di un programma che stampa "Hello World Console " utilizzando la classe.The following example program can generate and compile source code based on a CodeDOM model of a program that prints "Hello World" using the Console class. Viene fornita un'interfaccia utente di Windows Forms.A Windows Forms user interface is provided. L'utente può selezionare il linguaggio di programmazione di destinazione da diverse selezioni: C#, Visual Basic e JScript.The user can select the target programming language from several selections: C#, Visual Basic, and JScript.

Un CodeDomProvider oggetto può essere usato per creare e recuperare istanze di generatori di codice e compilatori di codice.A CodeDomProvider can be used to create and retrieve instances of code generators and code compilers. È possibile utilizzare i generatori di codice per generare codice in un linguaggio particolare e i compilatori di codice per compilare codice in assembly.Code generators can be used to generate code in a particular language, and code compilers can be used to compile code into assemblies.

Nota

In i .NET Framework 2.0.NET Framework 2.0metodi resi disponibili nel generatore di codice e nel compilatore di codice sono disponibili direttamente dal provider di codice.In the .NET Framework 2.0.NET Framework 2.0, the methods made available in the code generator and code compiler are available directly from the code provider. Non è necessario chiamare CreateGenerator o CreateCompiler per accedere ai metodi e tali metodi sono contrassegnati come obsoleti.You do not need to call CreateGenerator or CreateCompiler to access the methods, and those methods are marked as obsolete. Questo vale per le implementazioni preesistenti e nuove del provider di codice.This applies to preexisting as well as new code provider implementations.

Un' CodeDomProvider implementazione di in genere fornisce la generazione di codice e/o le interfacce di compilazione del codice per la generazione di codice e la gestione della compilazione per un unico linguaggio di programmazioneA CodeDomProvider implementation typically provides code generation and/or code compilation interfaces for generating code and managing compilation for a single programming language. Diverse lingue sono supportate dalle CodeDomProvider implementazioni fornite con il Windows SDK.Several languages are supported by CodeDomProvider implementations that ship with the Windows SDK. Questi linguaggi includono C#, Visual Basic, C++ e JScript.These languages include C#, Visual Basic, C++, and JScript. Gli sviluppatori o i fornitori di compilatori possono implementare le CodeDomProvider interfacce e ICodeCompiler e fornire un che estende il ICodeGenerator supporto CodeDom ad altri linguaggi di programmazione.Developers or compiler vendors can implement the ICodeGenerator and ICodeCompiler interfaces and provide a CodeDomProvider that extends CodeDOM support to other programming languages.

L' <elemento System.> CodeDom nel file di configurazione del computer (Machine. config) fornisce un meccanismo per gli sviluppatori e i fornitori di compilatori CodeDomProvider per aggiungere impostazioni di configurazione per implementazioni aggiuntive.The <system.codedom> Element in the machine configuration file (Machine.config) provides a mechanism for developers and compiler vendors to add configuration settings for additional CodeDomProvider implementations.

La CodeDomProvider classe fornisce metodi statici per individuare ed enumerare CodeDomProvider le implementazioni in un computer.The CodeDomProvider class provides static methods to discover and enumerate the CodeDomProvider implementations on a computer. Il GetAllCompilerInfo metodo restituisce le impostazioni per tutte CodeDomProvider le implementazioni in un computer.The GetAllCompilerInfo method returns the settings for all CodeDomProvider implementations on a computer. Il GetCompilerInfo metodo restituisce le impostazioni per un'implementazione CodeDomProvider specifica, in base al nome del linguaggio di programmazione.The GetCompilerInfo method returns the settings for a specific CodeDomProvider implementation, based on the programming language name. Il CreateProvider metodo restituisce un'istanza di un' CodeDomProvider implementazione di per una lingua specifica.The CreateProvider method returns an instance of a CodeDomProvider implementation for a specific language.

Per ulteriori informazioni sulle impostazioni del provider del linguaggio nel file di configurazione, vedere schema delle impostazioni del compilatore e del provider del linguaggio.For more details on language provider settings in the configuration file, see Compiler and Language Provider Settings Schema.
