CompilerInfo.GetExtensions Method

Definition

Returns the file name extensions supported by the language provider.

C#
public string[] GetExtensions();

Returns

String[]

An array of file name extensions supported by the language provider.

Examples

The following code example enumerates the language providers on the computer and displays the configuration and compiler settings for each language provider. This code example is part of a larger example provided for the CompilerInfo class.

C#
CompilerInfo [] allCompilerInfo = CodeDomProvider.GetAllCompilerInfo();
foreach (CompilerInfo info in allCompilerInfo)
{
    String defaultLanguage;
    String defaultExtension;

    CodeDomProvider provider = info.CreateProvider();

    // Display information about this configured provider.

    Console.WriteLine("Language provider:  {0}",
        provider.ToString());
    Console.WriteLine();

    Console.WriteLine("  Supported file extension(s):");
    foreach(String extension in info.GetExtensions())
    {
        Console.WriteLine("    {0}", extension);
    }

    defaultExtension = provider.FileExtension;
    if (defaultExtension[0] != '.')
    {
        defaultExtension = "." + defaultExtension;
    }
    Console.WriteLine("  Default file extension:  {0}",
        defaultExtension);
    Console.WriteLine();

    Console.WriteLine("  Supported language(s):");
    foreach(String language in info.GetLanguages())
    {
        Console.WriteLine("    {0}", language);
    }

    defaultLanguage = CodeDomProvider.GetLanguageFromExtension(defaultExtension);
    Console.WriteLine("  Default language:        {0}",
        defaultLanguage);
    Console.WriteLine();

    // Get the compiler settings for this provider.
    CompilerParameters langCompilerConfig = info.CreateDefaultCompilerParameters();

    Console.WriteLine("  Compiler options:        {0}",
        langCompilerConfig.CompilerOptions);
    Console.WriteLine("  Compiler warning level:  {0}",
        langCompilerConfig.WarningLevel);
    Console.WriteLine();
}

Remarks

The <system.codedom> Element in the machine configuration file contains the language provider and compiler configuration settings for each CodeDomProvider implementation on the computer. Each configured language provider supports one or more file name extensions. For example, a Microsoft.CSharp.CSharpCodeProvider might support the file name extensions ".cs" and ".c#".
