What?
The Helper Trinity is a set of helper classes applicable to most any .NET application. Using the classes in this library, you can much more easily validate arguments, raise events, and throw exceptions.
Why?
Writing code to check arguments, raise events, and throw exceptions is mundane and error-prone. The Helper Trinity alleviates you of the need to write such code over and over again.
Where?
Documentation, binaries, and source for The Helper Trinity can be downloaded from the
releases section.
How?
private static readonly ExceptionHelper _exceptionHelper = new ExceptionHelper(typeof(MyType));
public event EventHandler<EventArgs> GettingContent;
public string GetContent(Uri uri, ContentFormat format)
{
//validate arguments
uri.AssertNotNull("uri");
format.AssertEnumMember("format");
//validate environment
_exceptionHelper.ResolveAndThrowIf(!ConnectedToInternet, "NotConnected");
//raise an event
GettingContent.Raise(this, EventArgs.Empty);
try
{
//get and return the content
...
}
catch (WebException ex)
{
//throw a more appropriate exception
throw _exceptionHelper.Resolve("InvalidState", ex);
}
}
