通过SharpZipLib来压缩解压文件

在项目开发中，一些比较常用的功能就是压缩解压文件了，其实类似的方法有许多 ，现将通过第三方类库SharpZipLib来压缩解压文件的方法介绍如下，主要目的是方便以后自己阅读，当然可以帮到有需要的朋友更好了，代码比较简单。

public class ZipAndUnzipFileBySharpZipLib
{
/// <summary>
/// 解压文件
/// </summary>
/// <param name="SrcFile"></param>
/// <param name="DstFolder"></param>
public static void UnZip(string SrcFile, string DstFolder)
{
FileStream fileStreamIn = new FileStream(SrcFile, FileMode.Open, FileAccess.Read);
ZipInputStream zipInStream = new ZipInputStream(fileStreamIn);
ZipEntry entry = zipInStream.GetNextEntry();
while (entry != null)
{
FileStream fileStreamOut = new FileStream(DstFolder + @"\" + entry.Name, FileMode.Create, FileAccess.Write);
int size;
byte[] buffer = new byte[1024];
do
{
size = zipInStream.Read(buffer, 0, buffer.Length);
fileStreamOut.Write(buffer, 0, size);
}
while (size > 0);
fileStreamOut.Close();

entry = zipInStream.GetNextEntry();
}
zipInStream.Close();
fileStreamIn.Close();
}

/// <summary>
/// 压缩文件或目录
/// </summary>
/// <param name="srcPath"></param>
/// <param name="dstFile"></param>
public static void Zip(string srcPath, string dstFile)
{
bool isFile = false;
bool isFolder = false;
if(File.Exists(srcPath))
{
isFile = true;
}
if(Directory.Exists(srcPath))
{
isFolder = true;
}
if (isFile == false && isFolder == false) { return; }
FileStream fileStreamOut = new FileStream(dstFile, FileMode.Create, FileAccess.Write);
ZipOutputStream zipOutputStream = new ZipOutputStream(fileStreamOut);
if(isFile)
{
ZipFile(srcPath,zipOutputStream);
}
if(isFolder)
{
IEnumerable<string> files = Directory.EnumerateFiles(srcPath);
foreach (var file in files)
{
ZipFile(file, zipOutputStream);
}
}
zipOutputStream.Close();
fileStreamOut.Close();
}

/// <summary>
/// 压缩文件
/// </summary>
/// <param name="srcFile">待压缩的文件路径</param>
/// <param name="zipOutputStream">压缩stream</param>

private static void ZipFile(string srcFile,ZipOutputStream zipOutputStream)
{
FileStream fileStreamIn = new FileStream(srcFile, FileMode.Open, FileAccess.Read);
byte[] buffer = new byte[1024];
ZipEntry entry = new ZipEntry(Path.GetFileName(srcFile));
zipOutputStream.PutNextEntry(entry);
int size;
do
{
size = fileStreamIn.Read(buffer, 0, buffer.Length);
zipOutputStream.Write(buffer, 0, size);
} while (size > 0);
fileStreamIn.Close();
}
}
