Read & Recognize Barcode from Local Images in .NET Applications

Free Resource
This technical tip allows developers to read barcode from local image using Saaspose.BarCode REST API in your .NET applications. Some important steps for performing this task is to specify base product URI. This URI depends upon the version of the API you want to use in your application, build URI to upload file, enter app key and app SID, enter file name with full path, build remote URI to generate barcode, Sign remote URI, Send request and read barcode and Display the value and type of all the recognized barcodes.
//build URI to upload file
            string fileUploadUri = "http://api.saaspose.com/v1.0/storage/file/test.jpg";
            string UploadUrl = Sign(fileUploadUri);
            // Send request to upload file
            UploadFileBinary("c:\\temp\\test.jpg", UploadUrl, "PUT");

            //build URI to read barcode
            string strURI = "http://api.saaspose.com/v1.0/barcode/test.jpg/recognize?type=AllSupportedTypes";
            // Send the request to Saaspose server
            Stream responseStream = ProcessCommand(Sign(strURI), "GET");
            StreamReader reader = new StreamReader(responseStream);
            // Read the response
            string strJSON = reader.ReadToEnd();
            //Parse the json string to JObject
            JObject parsedJSON = JObject.Parse(strJSON);
            //Deserializes the JSON to a object. 
            RecognitionResponse barcodeRecognitionResponse = JsonConvert.DeserializeObject
            // Display the value and type of all the recognized barcodes
            foreach (RecognizedBarCode barcode in barcodeRecognitionResponse.Barcodes)
                Console.WriteLine("Codetext: " + barcode.BarCodeValue + "\nType: " + barcode.BarCodeType);

	    \\Here is the RecognitionResponse class
	    public class RecognitionResponse : BaseResponse
        	public List
    Barcodes { get; set; }

	    \\Here is the RecognizedBarCode class	    
	    public class RecognizedBarCode
        	public string BarCodeType { get; set; }
        	public string BarCodeValue { get; set; }

	    \\Here is the BaseResponse class	    
	    public class BaseResponse
        	public BaseResponse() { }
        	public string Code { get; set; }
        	public string Status { get; set; }
