已取代。 取得變數是必要還是選擇性。

public:
 property bool IsRequired { bool get(); };
bool IsRequired();
/// [get: Windows.Foundation.Metadata.Deprecated("Use ILearningModelFeatureDescriptor instead of ILearningModelVariableDescriptorPreview. For more info, see MSDN.", Windows.Foundation.Metadata.DeprecationType.Deprecate, 131072, "Windows.AI.MachineLearning.Preview.MachineLearningPreviewContract")]

var boolean = iLearningModelVariableDescriptorPreview.isRequired;

bool

如果需要變數，則為 True;否則為 false。

範例

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;

	//Verify if the input feature is required or optional.
    if (imageDescriptor.IsRequired == true)
    {
        Console.WriteLine($"Input Feature Name: {imageDescriptor.Name} is required.");
    }
 }

備註

警告

這是已被取代的 API。 請改用 Windows.AI.MachineLearning 命名空間。
