vs2005如何制作自解压软件

[luc_ne]

想实现那种像winrar制作的自解压exe文件那样
可以在没有winrar的环境下运行
运行时将压缩包解压，解压完毕可以自动运行某个文件。

现在用vb.net实现了解压和运行的功能，但bin\debug下是一堆
data\xxx.zip,xxx.exe,xxx.config的文件，能否把它们搞成一个exe文件，运行起来和运行xxx.exe一样的效果

希望大家谈谈自己的看法

Gzip组件应该可以实现吧，没做过

打一个包，把他放在 exe 文件后面
比如 exe 文件是 1000 字节
压缩包是 1000 字节
哪么最终就是 2000 字节

exe 文件后面设置一个起始为如 FF 00 FF CC XX
后面的就是压缩文件；

exe 运行后读取自己，找到 FF 00 FF CC XX 后
后面的就都是压缩包了，然后借用运行里面的东西

原理就是这样

或者用资源文件更简单一些（msdn上有列子）

我了解好像有一个算法对文件进行压缩和解压的

sharpzip 提供开源代码 很好用的

[ericzhangbo1982111]

可以自己写一个解压缩的类
解压算法网上有公开的
如果你不想很头疼的话
就用SharpZipLib.dll
这个很方便

把你要解压的文件放到你说的xx.exe中就可以了

using System;
using System.IO;

using ICSharpCode.SharpZipLib.Zip;

class MainClass
{

public static void Main(string[] args)
{
// Perform some simple parameter checking. More could be done
// like checking the target file name is ok, disk space, and lots
// of other things, but for a demo this covers some obvious traps.
if ( args.Length < 2 ) {
Console.WriteLine("Usage: CreateZipFile Path ZipFile");
return;
}

if ( !Directory.Exists(args[0]) ) {
Console.WriteLine("Cannot find directory '{0}'", args[0]);
return;
}

try
{
// Depending on the directory this could be very large and would require more attention
// in a commercial package.
string[] filenames = Directory.GetFiles(args[0]);

// 'using' statements gaurantee the stream is closed properly which is a big source
// of problems otherwise. Its exception safe as well which is great.
using (ZipOutputStream s = new ZipOutputStream(File.Create(args[1]))) {

s.SetLevel(9); // 0 - store only to 9 - means best compression

byte[] buffer = new byte[4096];

foreach (string file in filenames) {

// Using GetFileName makes the result compatible with XP
// as the resulting path is not absolute.
ZipEntry entry = new ZipEntry(Path.GetFileName(file));

// Setup the entry data as required.

// Crc and size are handled by the library for seakable streams
// so no need to do them here.

// Could also use the last write time or similar for the file.
entry.DateTime = DateTime.Now;
s.PutNextEntry(entry);

using ( FileStream fs = File.OpenRead(file) ) {

// Using a fixed size buffer here makes no noticeable difference for output
// but keeps a lid on memory usage.
int sourceBytes;
do {
sourceBytes = fs.Read(buffer, 0, buffer.Length);
s.Write(buffer, 0, sourceBytes);
} while ( sourceBytes > 0 );
}
}

// Finish/Close arent needed strictly as the using statement does this automatically

// Finish is important to ensure trailing information for a Zip file is appended. Without this
// the created file would be invalid.
s.Finish();

// Close is important to wrap things up and unlock the file.
s.Close();
}
}
catch(Exception ex)
{
Console.WriteLine("Exception during processing {0}", ex);

// No need to rethrow the exception as for our purposes its handled.
}
}
}
