示例1: ReloadOnChanged
public static IConfigurationRoot ReloadOnChanged(
this IConfigurationRoot config,
IFileProvider fileProvider,
string filename)
{
if (config == null)
{
throw new ArgumentNullException(nameof(config));
}
if (fileProvider == null)
{
throw new ArgumentNullException(nameof(fileProvider));
}
if (filename == null)
{
throw new ArgumentNullException(nameof(filename));
}
Action<object> callback = null;
callback = _ =>
{
// The order here is important. We need to take the token and then apply our changes BEFORE
// registering. This prevents us from possible having two change updates to process concurrently.
//
// If the file changes after we take the token, then we'll process the update immediately upon
// registering the callback.
var token = fileProvider.Watch(filename);
config.Reload();
token.RegisterChangeCallback(callback, null);
};
fileProvider.Watch(filename).RegisterChangeCallback(callback, null);
return config;
