BuildProvider.CodeCompilerType 属性

定义

命名空间:

System.Web.Compilation

程序集:

System.Web.dll

表示生成提供程序为自定义文件类型生成源代码所使用的编译器类型。

public:
 virtual property System::Web::Compilation::CompilerType ^ CodeCompilerType { System::Web::Compilation::CompilerType ^ get(); };

public virtual System.Web.Compilation.CompilerType CodeCompilerType { get; }

member this.CodeCompilerType : System.Web.Compilation.CompilerType

Public Overridable ReadOnly Property CodeCompilerType As CompilerType

属性值

CompilerType

只读 CompilerType，表示用于生成虚拟路径的源代码的代码生成器、代码编译器和编译器设置。 基类返回 null。

示例

下面的代码示例演示了从抽象 BuildProvider 基类继承的简单生成提供程序实现。 生成提供程序将CodeCompilerTypeGetGeneratedType替代基类的成员和GenerateCode成员。

注解

CodeCompilerType使用属性提供用于编译实现的源代码的设置BuildProvider。 该 CodeCompilerType 属性是 null ，如果生成提供程序不需要特定代码语言来生成和编译源代码。

若要在生成提供程序实现中设置对象的值 CompilerType ，请使用 GetDefaultCompilerType 或 GetDefaultCompilerTypeForLanguage 方法。

该 CodeDomProviderType 属性指定 CodeDomProvider 用于生成和编译生成提供程序的源代码的实现。 该 CompilerParameters 属性定义用于将源代码编译为程序集的设置。
