This article introduces you about the common sense of VS2003 compression code, the content is very detailed, interested friends can refer to, hope to be helpful to you.

1. First download the 0.84 version of VS2003 compression code and sample code from here.

2. After downloading it, you find that it doesn't have a VS2003 solution file, it doesn't matter. You can create your own, first create a new ZipUnzip solution, and then COPY all the unzipped files and directories above to the same directory as your solution.

Microsoft employees are concerned about Visual Studio2003 code editing

A few minutes to let you know the match of Visual Studio Boost.

It strongly shows that the relevant skills of Visual Studio debugging are the same as those of

Download and install the annoying Visual Studio 2005 SP1

Visual Studio 2010 develops and deploys 64-bit programs

3, in VS2003 solution Explorer (usually in the upper right middle point of the location), click the Show all files button, and then you can see a lot of "virtual" icons, files and folders, etc., you can select them at once, and then include them in the project.

4. Compile, * use the Release option. After compilation is complete, you can see the ZipUnzip.dll class in\ bin\ Release\. If you make a mistake in compiling the Times and say something like AssemblyKeyFile, you can use the strong naming tool to create a new one, or you can add [assembly: AssemblyKeyFile (")] in AssemblyInfo.cs. Change it to: [assembly: AssemblyKeyFile (")] (not recommended).

5. Create a new WEBFORM project, add a reference to the ZipUnzip.dll class, and then add the following files and contents:

Using System; using System.IO; using ICSharpCode.SharpZipLib.Zip; using ICSharpCode.SharpZipLib.GZip; using ICSharpCode.SharpZipLib.BZip2; using ICSharpCode.SharpZipLib.Checksums; using ICSharpCode.SharpZipLib.Zip.Compression; using ICSharpCode.SharpZipLib.Zip.Compression.Streams; namespace WebZipUnzip {public class AttachmentUnZip {public AttachmentUnZip () {} public static void UpZip (string zipFile) {string [] FileProperties=new string [2]; FileProperties [0] = zipFile / / File to be unzipped FileProperties [1] = zipFile.Substring (0ZipFile.LastIndexOf ("\") + 1); / / Target directory UnZipClass UnZc=new UnZipClass (); UnZc.UnZip (FileProperties) }} / /-/ / 2.
