C#文件或文件夹压缩方法有很多，本文通过使用ICSharpCode.SharpZipLib.dll来进行压缩，解压也可以但是本文暂不涉及...
如果没有引用ICSharpCode.SharpZipLib包，可以通过工具-nuget包管理器-管理nuget包搜素，然后安装引用
下面直接上代码，为压缩zip代码
/// 压缩成zip
/// </summary>
/// <param name="filesPath">d:\</param>
/// <param name="zipFilePath">d:\a.zip</param>
public static void CreateZipFile(string folderToZip, string zipedFile)
{
bool result = false;
if (!Directory.Exists(folderToZip))
return ;
ZipOutputStream zipStream = new ZipOutputStream(File.Create(zipedFile));
zipStream.SetLevel(6);
//if (!string.IsNullOrEmpty(password)) zipStream.Password = password;
result = ZipDirectory(folderToZip, zipStream, "");
zipStream.Finish();
zipStream.Close();
return ;
}
/// <summary>

private static bool ZipDirectory(string folderToZip, ZipOutputStream zipStream, string parentFolderName)
{
bool result = true;
string[] folders, files;
ZipEntry ent = null;
FileStream fs = null;
//Crc32 crc = new Crc32();
try
{
ent = new ZipEntry(Path.Combine(parentFolderName, Path.GetFileName(folderToZip) + "/"));
zipStream.PutNextEntry(ent);
zipStream.Flush();
files = Directory.GetFiles(folderToZip);
foreach (string file in files)
{
fs = File.OpenRead(file);
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
ent = new ZipEntry(Path.Combine(parentFolderName, Path.GetFileName(folderToZip) + "/" + Path.GetFileName(file)));
ent.DateTime = DateTime.Now;
ent.Size = fs.Length;
fs.Close();
//crc.Reset();
//crc.Update(buffer);
//ent.Crc = crc.Value;
zipStream.PutNextEntry(ent);
zipStream.Write(buffer, 0, buffer.Length);
}
}
catch
{
result = false;
}
finally
{
if (fs != null)
{
fs.Close();
fs.Dispose();
}
if (ent != null)
{

GC.Collect();
GC.Collect(1);

folders = Directory.GetDirectories(folderToZip);
