# TaskSettingNameArray

Parameter `TaskSettingNameArray` represents the collection of task setting object names, used to refer to the [`BarcodeReaderTaskSetting`](https://www.dynamsoft.com/capture-vision/docs/core/parameters/file/task-settings/barcode-reader-task-settings.md),[`LabelRecognizerTaskSetting`](https://www.dynamsoft.com/capture-vision/docs/core/parameters/file/task-settings/label-recognizer-task-settings.md),[`DocumentNormalizerTaskSetting`](https://www.dynamsoft.com/capture-vision/docs/core/parameters/file/task-settings/document-normalizer-task-settings.md), [`OutputTaskSetting`](https://www.dynamsoft.com/capture-vision/docs/core/parameters/file/task-settings/output-task-setting.md) objects. It is used to define recognition tasks such as reading barcodes, recognizing labels, or detecting document quads.
