// <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,
// if one exists.
// <exe_name> Extension .vb

注解
CompilerInfo使用 类可以确定是在计算机上配置了实现，还是CodeDomProvider检查特定语言提供程序的配置和编译器设置。
计算机配置文件中的 system.codedom> 元素包含语言提供程序和编译器配置设置。< 每个配置的语言提供程序都有相应的编译器配置元素。 每个元素定义 CodeDomProvider 实现类型、支持的语言名称、支持的文件扩展名和编译器参数。
.NET Framework在计算机配置文件中定义初始编译器设置。 开发人员和编译器供应商可以添加新 CodeDomProvider 实现的配置设置。
类 CompilerInfo 提供对计算机配置文件中这些设置的只读访问权限。 GetLanguages使用 、 GetExtensions和 CodeDomProviderType 成员检查语言提供程序的相应配置属性。 CreateDefaultCompilerParameters使用 方法获取语言提供程序的编译器选项和警告级别属性值。
有关配置文件中语言提供程序设置的详细信息，请参阅 编译器和语言提供程序设置架构。
注意
此类包含在类级别应用于所有成员的链接需求。 SecurityException当直接调用方没有完全信任权限时，将引发 。 有关链接需求的详细信息，请参阅 链接需求。
