// print out the hashcode Console.WriteLine("Hash code: {0}", Convert.ToBase64String(hashCode)); // wait for input before exiting Console.WriteLine("Press enter to finish"); Console.ReadLine(); } } I create a Stream from the file using the System.IO.File class. You can find details of this class and other ways to open files in 20. I create my HashAlgorithm object and then pass the Stream as a parameter to the ComputeHash method. The contents of the file are read in, and the hash code is returned as a byte array. Once again, I encode the bytes using base 64 so we can read them more readily. The result of compiling and running Listing 37-7 is as follows: Hash code: jgtZ8C7iFrBr7YRGBqKtN8e8zNTw9Fq791QyOKz2+/E= Press enter to finish

New QR Code Reader Library - DZone Mobile
Apr 3, 2018 · This article discusses a new free QR Code detector that has been released as part of an existing open source computer vision library.

To validate a hash code, we need the data and the hash code that the person who sent us the data has generated. We then use the same hash algorithm to generate our own hash code, and if the two match, we can be confident that the data we received is the data that was sent to us and has not been modified in any way. Listing 37-8 demonstrates validating the checksum we generate in Listing 37-7. Listing 37-8. Validating a Hash Code using using using using System; System.IO; System.Linq; System.Security.Cryptography;

class Listing 08 { static void Main(string[] args) { // define the hash code we were sent string originalHashCodeString = "jgtZ8C7iFrBr7YRGBqKtN8e8zNTw9Fq791QyOKz2+/E="; // decode the hash code to get the bytes byte[] originalHashCode = Convert.FromBase64String(originalHashCodeString); // open a stream to the file Stream myStream = File.OpenRead(@"..\..\datafile.txt"); // create the hash algorithm object HashAlgorithm myHashAlgorithm = new SHA256Managed(); // generate the new hash code for the data

A more elegant solution to type ambiguity is to use the C# namespace alias feature. This allows you to assign a new name to a type in a namespace one that doesn t collide with a type in another namespace. Listing 11-14 provides a demonstration, with the namespace alias statements shown in bold. Listing 11-14. Disambiguating with Namespace Aliases using using using using BillingSystem; OrderSystem; BillingProduct = BillingSystem.Product; OrderProduct = OrderSystem.Product;

Reading QR code using Webcam in Java - GitHub Community Forum
Some clarification about the error message you are getting: https://stackoverflow. com/a/18138276. Also, next time please post your code or ...

namespace AuditSystem { class Audit { public static void Main(string[] args) { // create a new instance of a type from // the BillingSystem namespace Bill b = new Bill(); // create a new instance of a type from // the OrderSystem namespace Order o = new Order(); // create instances of each of the Product classes BillingProduct p1 = new BillingProduct(); OrderProduct p2 = new OrderProduct(); } } } You use the using keyword, but instead of importing a namespace, you specify the new name you want to use for a type, followed by the equals sign and then the name of the type you want to alias. So, the following statement:

using BillingProduct = BillingSystem.Product;

creates a new alias for the BillingSystem.Product type called BillingProduct. You can then create new instances of BillingProduct, and the C# system knows to translate that back to BillingSystem.Product. I have created two aliases in Listing 11-14, one for each of the types called Product. I could have just created one alias to avoid the name conflict, but it is good practice to alias all of the conflicting types so you don t inadvertently use the original name.

Another way of disambiguating types is to use the fully qualified names but alias those names to a shorter name. This has the benefit of applying to all the types in a namespace, rather than just one type as we saw in the previous section. Listing 11-15 demonstrates how to alias an entire namespace, with the alias statements shown in bold. Listing 11-15. Disambiguating by Aliasing an Entire Namespace using B = BillingSystem; using O = OrderSystem; namespace AuditSystem { class Audit { public static void Main(string[] args) {
