C #. NET uses the third-party class library DotNetZip to decompress/compress the Zip rarfile,

DotNetZip on CodePlex: http://dotnetzip.codeplex.com/

For details, see the source code ...... In short, it feels better than SharpZipLib. In addition, DotNetZip supports VB, C #, and any. NET language.

Compression:

// Define the file path string filename = @ "d:/test.rar"; using (ZipFile zip = new ZipFile () {zip. addFile (@ "C:/text.txt", "txt"); // store the text file in the txt folder zip. addFile (@ "C:/ReadMe.txt"); // store the ReadMe file in the zip directory. addFile (@ "C:/test.jpg", "images"); // store the test file in the images folder}

　　

Decompress:

using (ZipFile zip = new ZipFile(filename))            {                zip.ExtractAll("d:\\test", ExtractExistingFileAction.OverwriteSilently);            }

　　

C language ^ how to use

A1 = 0x01; // 0000 0001
A2 = 0x00; // 0000 0000
A3 = 0x03; // 0000 0011
A4 = 0x02; // 0000 0010

B1 = a1 ^ a2; // 0000 0001
B2 = a1 ^ a3; // 0000 0010
B3 = a1 ^ a4; // 0000 0011

^ XOR operator. The bitwise value is 0 and the difference is 1. See the example above.

//
Examples of simple and practical problems:
====================================
======= A ======= B =========
There are two circuits on the top. The two switches are a and B respectively. The opening status is \ [1], and the closing status is/[0].
If both circuits are enabled or disabled.
If a turns on [1], B turns off [0], and circuit 1 Powers on
=====================
If a disables [0], B enables [1], and circuit 2 powers on.
====================================
In summary, the circuit fails in the and B states simultaneously [0]. When a and B are different, the power is charged [1].
