備註

CodeDomProvider可用來建立和擷取程式代碼產生器和程式代碼編譯程式的實例。 程式碼產生器可以用來產生特定語言的程式碼,且程式碼編譯器可將程式碼編譯為組件。

注意

在 .NET Framework 2.0 中,程式代碼產生器和程式代碼編譯程式中提供的方法可直接從程式代碼提供者取得。 您不需要呼叫 CreateGeneratorCreateCompiler 來存取方法,而且這些方法會標示為過時。 這適用於既有的程式代碼提供者實作,以及新的程式代碼提供者實作。

CodeDomProvider 作通常會提供程式碼產生和/或程式代碼編譯介面,以產生程式代碼和管理單一程式設計語言的編譯。 Windows SDK 隨附的實作支持 CodeDomProvider 數種語言。 這些語言包括 C#、Visual Basic、C++和 JScript。 開發人員或編譯程式廠商可以實作 ICodeGeneratorICodeCompiler 介面,並提供 CodeDomProvider 將 CodeDOM 支援延伸至其他程式設計語言的 。

計算機組態檔中的 system.codedom> 元素 (Machine.config) 提供一種機制,讓開發人員和編譯程式廠商新增其他實作的組態設定。<CodeDomProvider

類別 CodeDomProvider 提供靜態方法來探索及列舉 CodeDomProvider 計算機上的實作。 方法 GetAllCompilerInfo 會傳回電腦上所有 CodeDomProvider 實作的設定。 方法 GetCompilerInfo 會根據程式設計語言名稱傳回特定 CodeDomProvider 實作的設定。 方法 CreateProvider 會傳回特定語言實作的 CodeDomProvider 實例。

如需組態檔中語言提供者設定的詳細資訊,請參閱 編譯程式和語言提供者設定架構

注意

這個類別會在類別層級建立連結需求和繼承需求。 SecurityException如果立即呼叫端或衍生類別沒有完全信任許可權,則會擲回 。 如需安全性需求的詳細資訊,請參閱 連結需求繼承需求

給實施者的注意事項

在 .NET Framework 1.0 和 1.1 版中,程式代碼提供者是由 、 ICodeGeneratorICodeParserICodeCompiler的實作CodeDomProvider所組成。 在 .NET Framework 2.0 中CreateGenerator(),、 CreateParser()CreateCompiler() 方法已過時,且 和 ICodeCompiler 的方法ICodeGenerator可直接在 類別中使用CodeDomProvider。 您應該覆寫程式代碼提供者實作中的那些方法,而不是呼叫基底方法。
