Compressing and Decompressing Files With C#
To reduce the time needed for files to be transmitted over a network, Compression and Decompression techniques are very useful. Developers prefer to write code to compress files before sending them out to the network for a file upload process. Web applications get the most benefit out of it. The .NET Framework provides the System.IO.Compression namespace, which contains the compressing and decompressing libraries and streams. Developers can use these types to read and modify the contents of a compressed file.
Creating Captcha Images for Security with an ASP.NET Application
CAPTCHA (Completely Automated Public Turing test to Tell Computers and Humans Apart) is a security check to distinguish between humans and computers. Computers or bots are not capable of solving a Captcha problem. Captcha is automatically generated with a random string. Generally, Captcha is generated by using an image with text/numbers or combination of both. A human has to enter the correct Captcha code to pass through the security check. Captcha technology is used mostly to block spammers who try to sign up and hack information from Web sites, blogs, or forums.

Deciding When to Use Weak References in .NET
The .NET WeakReference Class represents a weak reference, which references an object while still allowing that object to be reclaimed by garbage collection. Now, let's see an example. Create a console application from Visual Studio and name it MyWeakReference.
Create a WeakReference object and pass an object reference to the constructor call. In the following example, I have used the StringBuilder object.
