Windows系統(tǒng)中C#調(diào)用WinRAR來壓縮和解壓縮文件的方法
更新時(shí)間:2016年04月08日 16:32:07 作者:hzy3774
這篇文章主要介紹了Windows系統(tǒng)中C#調(diào)用WinRAR來壓縮和解壓縮文件的方法,個(gè)人感覺在Windows中WinRAR相對(duì)7-zip更加穩(wěn)定一些,需要的朋友可以參考下
過程說明都在注釋里,我們直接來看代碼:
壓縮:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using ICSharpCode.SharpZipLib.Zip;
using System.Diagnostics;
public class winrar
{

/// </summary>
/// <param name="filesPath">壓縮文件及完整路徑(D:\abc)</param>
/// <param name="zipFilePath">壓縮包所存完整路徑(D:\a.zip或d:\a.rar)</param>
public static void CreateZipFile(string filesPath, string zipFilePath)
{
if (!Directory.Exists(filesPath))
{
Console.WriteLine("Cannot find directory '{0}'", filesPath);
return;
}
try
{
string[] filenames = Directory.GetFiles(filesPath);
using (ZipOutputStream s = new ZipOutputStream(File.Create(zipFilePath)))
{
s.SetLevel(9); // 壓縮級(jí)別 0-9
//s.Password = "123"; //Zip壓縮文件密碼
byte[] buffer = new byte[4096]; //緩沖區(qū)大小
foreach (string file in filenames)
{
ZipEntry entry = new ZipEntry(Path.GetFileName(file));
entry.DateTime = DateTime.Now;
s.PutNextEntry(entry);
using (FileStream fs = File.OpenRead(file))
{
int sourceBytes;
do
{
sourceBytes = fs.Read(buffer, 0, buffer.Length);
s.Write(buffer, 0, sourceBytes);
} while (sourceBytes > 0);
}
}
s.Finish();
s.Close();
}
}
catch (Exception ex)
{
AutoCompare.ErrorLog.SaveError(ex, "壓縮文件出錯(cuò)!");
}
}
#endregion
#region 解壓文件
/// <summary>
/// 解壓文件
/// </summary>
/// <param name="zipFilePath">解壓文件及完整路徑(d:\a.zip或d:\a.rar)</param>
public static void UnZipFile(string zipFilePath)
{
if (!File.Exists(zipFilePath))
{
Console.WriteLine("Cannot find file '{0}'", zipFilePath);
return;
}
using (ZipInputStream s = new ZipInputStream(File.OpenRead(zipFilePath)))
{
ZipEntry theEntry;
while ((theEntry = s.GetNextEntry()) != null)
{
Console.WriteLine(theEntry.Name);
string directoryName = Path.GetDirectoryName(theEntry.Name);
string fileName = Path.GetFileName(theEntry.Name);
// create directory
if (directoryName.Length > 0)
{
Directory.CreateDirectory(directoryName);
}
if (fileName != String.Empty)
{
using (FileStream streamWriter = File.Create(theEntry.Name))
{
int size = 2048;
byte[] data = new byte[2048];
while (true)
{
size = s.Read(data, 0, data.Length);
if (size > 0)
{
streamWriter.Write(data, 0, size);
}
else
{
break;
}
}
}
}
}
}
}
