remove_all_keys() [1/2]

void xtd::configuration::file_settings::remove_all_keys ( )

noexcept

Removes all keys from the global section.

Remarks

To write permanently use the xtd::configuration::file_settings::save method.

This method is equivalent to call xtd::configuration::file_settings::remove_all_keys (const xtd::string& section) with xtd::string::empty_string paramreter.

Examples

The following example shows how to create xtd::configuration::file_settings and use xtd::configuration::file_settings::reset, xtd::configuration::file_settings::write, xtd::configuration::file_settings::remove_all_keys and xtd::configuration::file_settings::save methods.

auto file = file_settings {"my_app.ini"};
file.reset();
file.write("main", "quit_application_on_main_form_closed", true);
file.write("pictures \"Menu\"", "file_open", "resources/symbolic_open.png");
file.write("pictures \"Menu\"", "file_save", "resources/symbolic_save.png");
file.remove_all_keys();
file.save();

my_app.ini:

[pictures "Menu"]
file_open = resources/symbolic_open.png
file_save = resources/symbolic_save.png
