CompilerInfo
Examples
The following code example displays language provider configuration settings. Command-line arguments are used to specify a language, file name extension, or provider type. For the given input, the example determines the corresponding language provider and displays the configured language compiler settings.
// 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,
// if one exists.
// <exe_name> Extension .vb
// - Displays settings for the compiler associated with the .vb
// file extension.

Remarks
Use the CompilerInfo class to determine whether a CodeDomProvider implementation is configured on the computer, or to examine the configuration and compiler settings for a specific language provider.
The <system.codedom> Element in the machine configuration file contains the language provider and compiler configuration settings. Each configured language provider has a corresponding compiler configuration element. Each element defines the CodeDomProvider implementation type, supported language names, supported file name extensions, and compiler parameters.
The .NET Framework defines the initial compiler settings in the machine configuration file. Developers and compiler vendors can add configuration settings for a new CodeDomProvider implementation.
The CompilerInfo class provides read-only access to these settings in the machine configuration file. Use the GetLanguages, GetExtensions, and CodeDomProviderType members to examine the corresponding configuration attributes for a language provider. Use the CreateDefaultCompilerParameters method to obtain the compiler options and warning level attribute values for a language provider.
For more details on language provider settings in the configuration file, see Compiler and Language Provider Settings Schema.
Note
This class contains a link demand at the class level that applies to all members. A SecurityException is thrown when the immediate caller does not have full-trust permission. For details about link demands, see Link Demands.
Properties
| CodeDomProviderType |
Gets the type of the configured CodeDomProvider implementation. |
| IsCodeDomProviderTypeValid |
Returns a value indicating whether the language provider implementation is configured on the computer. |
Methods
| CreateDefaultCompilerParameters() |
Gets the configured compiler settings for the language provider implementation. |
| CreateProvider() |
Returns a CodeDomProvider instance for the current language provider settings. |
| CreateProvider(IDictionary<String,String>) |
Returns a CodeDomProvider instance for the current language provider settings and specified options. |
| Equals(Object) |
Determines whether the specified object represents the same language provider and compiler settings as the current CompilerInfo. |
| GetExtensions() |
Returns the file name extensions supported by the language provider. |
| GetHashCode() |
Returns the hash code for the current instance. |
| GetLanguages() |
Gets the language names supported by the language provider. |
| GetType() |
Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone() |
Creates a shallow copy of the current Object. (Inherited from Object) |
