The Predictor class

The Predictor class, much like what was changed in the linear regression example, is simply modified to support the new model and return the classification:

1. We begin by passing in the two new classes, FileInput and FilePrediction, to the CreatePredictionEngine method:

var predictionEngine = MlContext.Model.CreatePredictionEngine<FileInput, FilePrediction>(mlModel);

2. Next, we create the FileInput object, setting the Strings property with the return value of the GetStrings method we wrote earlier:

var prediction = predictionEngine.Predict(new FileInput
{
    Strings = GetStrings(File.ReadAllBytes(inputDataFile))
});

3. Finally, we update the output call to the Console object with our file classification and probability:

Console.WriteLine(
                    $"Based on the file ({inputDataFile}) the file is classified as {(prediction.IsMalicious ? "malicious" : "benign")}" + 
                    $" at a confidence level of {prediction.Probability:P0}");
