说说我利用ICSharpCode进行压缩和解压缩的一些自己的一下实践过程
1：组件下载地址

3：参数类
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; namespace ZipCompress
{
/// <summary>
/// 解压缩的一些属性
/// </summary>
public class DeZipParameter
{
private string zip_FullPath = "";
private string zip_DirectoryName = "";
private string zip_Password = "";
/// <summary>
/// 要解压缩的文件的完整路径
/// </summary>
public string ZIPFullPath
{
get { return zip_FullPath; }
set { zip_FullPath = value; }
} /// <summary>

/// </summary>
public string ZIPDirectoryName
{

} /// <summary>

public string Password

set { zip_Password = value; }
}
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; namespace ZipCompress
{
/// <summary>
/// 压缩文件的类
/// </summary>
public class ZipParameter
{
private string zip_Name = "";
private string zip_DirectoryName = "";
private List<string> zip_FileList = new List<string>();
private string zip_Password = "";
private int zip_Level = ;
/// <summary>

{

}

public string Password
{

set { zip_Password = value; }
}

/// 压缩比例等级，默认为6，0 - store only to 9 - means best compression
/// </summary>
public int Level
{
get { return zip_Level; }
set { zip_Level = value; }
}
}
}
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text; namespace ZipCompress
{

set { sourceDirectory = value; }
}

/// </summary>

{

set { fileFilter = value; }
}

/// 是否遍历子目录，True就遍历，False则不遍历
/// </summary>
public bool Recurse
{
get { return recurse; }
set { recurse = value; }
}
}
}
4：使用
ZipParameter zp = new ZipParameter();
zp.Password = "";
zp.Level = ;
zp.ZIPDirectoryName = @"C:\Users\Public\Pictures\Sample Pictures\";
zp.ZIPName = "Test.zip";
zp.ZIPFileList.Add(@"C:\Users\Public\Pictures\Sample Pictures\Chrysanthemum.jpg");
zp.ZIPFileList.Add(@"C:\Users\Public\Pictures\Sample Pictures\Desert.jpg");
zp.ZIPFileList.Add(@"C:\Users\WH130406P\Documents\RelatedTemplate.xlsx"); DeZipParameter dzp = new DeZipParameter();
dzp.ZIPFullPath = @"D:\项目必备\开发实例\wf20131124.zip";
dzp.ZIPDirectoryName = @"C:\Users\Public\Pictures\Sample Pictures\Test";
dzp.Password = ""; ZipFolderParameter zfp = new ZipFolderParameter();
zfp.ZipFileName = @"C:\Users\Public\Pictures\Sample Pictures\zipFolder.zip";
zfp.SourceDirectory = @"D:\xs\項目";
zfp.Recurse = true; CompressFile cprFile = new CompressFile();
cprFile.ZipParameter = zp;
cprFile.DeZipParameter = dzp;
cprFile.ZipFolderParameter = zfp;
cprFile.Compress();
cprFile.Decompress();
cprFile.CompressFolder();
上面都是我使用的过程，都是实践成功了的
