Extensions for LightResults, an extremely light and modern Operation Result Pattern library for .NET.

LightResults.Extensions.ExceptionHandling

Provides extension methods for exception handling using LightResults.

Try method

The Try method will wrap the execution of an Action or Func in a try { } catch { } block. If an exception occurs, a failed result will be returned and the Exception will be added to the result as metadata.

With an Action

var result = action.Try();
if (result.IsSuccess)
{
    // Do something
}

With an Action with arguments

var result = action.Try(42);
if (result.IsSuccess)
{
    // Do something
}

With a Func

var result = func.Try();
if (result.IsSuccess)
{
    var value = result.Value;
    // Do something
}

With a Func with arguments

var result = func.Try(42);
if (result.IsSuccess)
{
    var value = result.Value;
    // Do something
}

Getting the Exception

var result = action.Try();
if (result.IsFailed)
{
    var ex = (Exception)result.Error.Metadata["Exception"];
    // Do something with the base exception type or...
    
    if (ex is ArgumentNullException argumentNullException)
    {
        // Do something with a specific exception type
    }
}
