示例

public void Evaluator(LearningModelPreview model)
{
	// Retrieve the first input feature which is an image
    ILearningModelVariableDescriptorPreview inputImageFeatureDescription = model.Description.InputFeatures.FirstOrDefault(feature=>feature.ModelFeatureKind == LearningModelFeatureKindPreview.Image);

    ImageVariableDescriptorPreview imageDescriptor = (ImageVariableDescriptorPreview)inputImageFeatureDescription;

	// Ensure the input feature handles the format RGBA8
    if (imageDescriptor.BitmapPixelFormat != BitmapPixelFormat.Rgba8)
    {
        Console.WriteLine($"Input Feature Name: {imageDescriptor.Name}. Format not supported.");
