Public Property EnableLineNumbers As Boolean
public bool EnableLineNumbers { get; set; }
Property Value
Type: System.Boolean
Returns true if the Line numbers option is enabled for use; otherwise, returns false.
Remarks
Visual Studio can display line numbers for any source file, helping users find particular lines of source. This ability is controlled from the Options dialog box (available from the Tools -> Options menu) with the option Line numbers. If a language service cannot support line numbers for some reason, then the EnableLineNumbers property should be set to false, thereby disabling the Line numbers option.
This property is available to any language service implementation.
The default is true when the corresponding registry entry is accessed through the LanguagePreferences class.
The registry entry looks like this:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\[X.Y]\Languages\Language Services\
[Language Name]\
EnableLineNumbersOption = reg_dword: 0x00000001
Examples
[ProvideLanguageService(typeof(MyLanguageService), // Required
MyConstants.languageName, // Required
MyConstants.languageNameResourceID, // Required
// Optional language service properties
EnableLineNumbers = true, // line numbers are supported
)]
