範例

下列程式代碼範例會顯示語言提供者組態設定。 命令行自變數可用來指定語言、擴展名或提供者類型。 針對指定的輸入，此範例會決定對應的語言提供者，並顯示已設定的語言編譯程序設定。

C#

// Command-line argument examples:
//      - Displays Visual Basic, C#, and JScript compiler settings.
//   <exe_name> Language CSharp
//      - Displays the compiler settings for C#.
//   <exe_name> All
//      - Displays settings for all configured compilers.
//   <exe_name> Config Pascal
//      - Displays settings for configured Pascal language provider,

備註

使用 類別 CompilerInfo 來判斷計算機上是否已 CodeDomProvider 設定實作，或檢查特定語言提供者的組態和編譯程序設定。

計算機組態檔中的 system.codedom> 元素包含語言提供者和編譯程式組態設定。< 每個設定的語言提供者都有對應的編譯程式組態專案。 每個元素都會 CodeDomProvider 定義實作類型、支援的語言名稱、支援的擴展名，以及編譯程序參數。

.NET Framework 會在計算機組態檔中定義初始編譯程式設定。 開發人員和編譯器廠商可以為新的 CodeDomProvider 實作新增組態設定。

類別 CompilerInfo 提供計算機組態檔中這些設定的唯讀存取權。 GetLanguages使用、 GetExtensions和 CodeDomProviderType 成員來檢查語言提供者的對應組態屬性。 CreateDefaultCompilerParameters使用方法來取得語言提供者的編譯程式選項和警告層級屬性值。

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

此類別包含套用至所有成員之類別層級的連結需求。 SecurityException當立即呼叫端沒有完全信任權限時，會擲回 。 如需連結需求的詳細資訊，請參閱 連結需求。

屬性

CodeDomProviderType	取得已設定 CodeDomProvider 之實作的類型。
IsCodeDomProviderTypeValid	傳回值，指出是否已在電腦上設定語言提供者實作。

方法

CreateDefaultCompilerParameters()	取得語言提供者實作的已設定編譯器設定。
CreateProvider()	傳回目前語言提供者設定的 CodeDomProvider 執行個體。
CreateProvider(IDictionary<String,String>)	傳回目前語言提供者設定和指定之選項的 CodeDomProvider 執行個體。
Equals(Object)	判斷指定的物件是否表示與目前 CompilerInfo 相同的語言提供者和編譯器設定。
GetExtensions()	傳回語言提供者支援的副檔名。
GetHashCode()	傳回目前執行個體的雜湊碼。
GetLanguages()	取得語言提供者支援的語言名稱。
GetType()	取得目前執行個體的 Type。 (繼承來源 Object)
MemberwiseClone()	建立目前 Object 的淺層複製。 (繼承來源 Object)
ToString()	傳回代表目前物件的字串。 (繼承來源 Object)
