易采站长站为您分析Windows系统中C#调用WinRAR来压缩和解压缩文件的方法,个人感觉在Windows中WinRAR相对7-zip更加稳定一些,需要的朋友可以参考下
过程说明都在注释里，我们直接来看代码：
压缩：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;
using ICSharpCode.SharpZipLib.Zip;
using System.Diagnostics;

/// <param name="filesPath">压缩文件及完整路径(D:abc)</param>
/// <param name="zipFilePath">压缩包所存完整路径(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); // 压缩级别 0-9
//s.Password = "123"; //Zip压缩文件密码
byte[] buffer = new byte[4096]; //缓冲区大小
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, "压缩文件出错！");
}
}

else
