大家好,我想问个问题
我用ICSharpZipLib类进行文件解压缩时,只能压缩文件夹里面的子文件，如果有子文件夹却不能压缩.
能帮我解决一下吗,下面是我的程序,
using System;
using System.Collections.Generic;
using System.Text;
using System.IO;
using System.IO.Compression;
using System.ComponentModel;
using ICSharpCode.SharpZipLib.Checksums;
using ICSharpCode.SharpZipLib.Zip;
using ICSharpCode.SharpZipLib.GZip;
using System.Diagnostics;
namespace SharpZipLib
{
class Program
{
public void ZipFile(string FileToZip, string ZipedFile, int CompressionLevel, int BlockSize)
{
//如果文件没有找到，则报错
if (!System.IO.File.Exists(FileToZip))
{
throw new System.IO.FileNotFoundException("The specified file " + FileToZip + " could not be found. Zipping aborderd");
}
System.IO.FileStream StreamToZip = new System.IO.FileStream(FileToZip, System.IO.FileMode.Open, System.IO.FileAccess.Read);
System.IO.FileStream ZipFile = System.IO.File.Create(ZipedFile);
ZipOutputStream ZipStream = new ZipOutputStream(ZipFile);
ZipEntry ZipEntry = new ZipEntry("ZippedFile");
ZipStream.PutNextEntry(ZipEntry);
ZipStream.SetLevel(CompressionLevel);
byte[] buffer = new byte[BlockSize];
System.Int32 size = StreamToZip.Read(buffer, 0, buffer.Length);
ZipStream.Write(buffer, 0, size);
try
{
while (size < StreamToZip.Length)
{
int sizeRead = StreamToZip.Read(buffer, 0, buffer.Length);
ZipStream.Write(buffer, 0, sizeRead);
size += sizeRead;
}
}
catch (System.Exception ex)
{
throw ex;
}
ZipStream.Finish();
ZipStream.Close();
StreamToZip.Close();
}
public void ZipFileMain(string[] args)//对文件进行压缩;
{
string[] filenames = Directory.GetFiles(args[0]);
Crc32 crc = new Crc32();
ZipOutputStream s = new ZipOutputStream(File.Create(args[1]));//新建压缩文件流 “ZipOutputStream”
s.SetLevel(6); // 0 - store only to 9 - means best compression
foreach (string file in filenames)
{
//打开要压缩的文件
FileStream fs = File.OpenRead(file);
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
ZipEntry entry = new ZipEntry(file);
entry.DateTime = DateTime.Now;
entry.Size = fs.Length;
fs.Close();
crc.Reset();
crc.Update(buffer);
entry.Crc = crc.Value;
s.PutNextEntry(entry);
s.Write(buffer, 0, buffer.Length);
}
s.Finish();
s.Close();
}
public static string ServerDir;
static void Main(string[] args)
{
int month = Convert.ToInt32(DateTime.Now.ToString("MM"));//只取当前月份;
int iOldMonth = month - 1;
string a = iOldMonth.ToString();
string year = DateTime.Now.ToString("yyyy");//只取当前年份;
string time = Convert.ToString (year + "-" + a);
System.Console.WriteLine(time);
string abc = "c://unzipped/" + time;
string[] FileProperties = new string[2];
FileProperties[0] = abc;//待压缩文件目录
ServerDir = FileProperties[0];
//ServerDir = Path.GetDirectoryName(".");
System.Console.WriteLine(ServerDir);
FileProperties[1] = "C://zip/a.zip"; //压缩后的目标文件
Program Zc = new Program();
Zc.AddZipEntry(FileProperties);
}
这个只能压缩我指定的文件夹里的子文件,文件夹里的子文件夹就不能压缩
请大家帮忙
