c盘压缩卷和d盘压缩卷合并（C多文件压缩与解压）
这个功能没什么可介绍的，大家都懂，直接上代码了。。
实现功能：
选择多个文件压缩成ZIP文件和解压ZIP文件
开发环境：
开发工具： Visual Studio 2013
.NET Framework版本：4.5
实现代码：
//需要添加ICSharpCode.SharpZipLib.Zip.dll到自己项目
private void btnCompressFile_Click(object sender, EventArgs e)
{
listFiles.Items.Clear();
OpenFileDialog ofd = new OpenFileDialog();
ofd.Multiselect = true;
if (ofd.ShowDialog() == DialogResult.OK)
{
listFiles.Items.AddRange(ofd.FileNames);
}
}
private void btnCompress_Click(object sender, EventArgs e)
{
if (listFiles.Items.Count == 0)
{
MessageBox.Show("请先选择需要压缩的文件");
return;
}
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "压缩文件|*.zip";
if (sfd.ShowDialog() == DialogResult.OK)
{
string[] files = new string[listFiles.Items.Count];
for (int i = 0; i < listFiles.Items.Count; i )
{
files[i] = listFiles.Items[i].ToString();
}
dynamic result;
using (ZipOutputStream outStream = new zipOutputStream(File.Create(sfd.FileName)))
{
result = Zip(files, outStream, "123");
}
MessageBox.Show(result.msg);
}
}
private void btnUnCompressFile_Click(object sender, EventArgs e)
{
FolderBrowserDialog fbd = new FolderBrowserDialog();
fbd.ShowNewFolderButton = true;
if (fbd.ShowDialog() == DialogResult.OK)
{
txtOutFile.Text = fbd.SelectedPath;
}
}
private void btnUnCompress_Click(object sender, EventArgs e)
{
if (string.IsNullOrWhiteSpace(txtOutFile.Text))
{
MessageBox.Show("请先选择解压路径");
return;
}
OpenFileDialog ofd = new OpenFileDialog();
ofd.Filter = "压缩文件|*.Zip";
if (ofd.ShowDialog() == DialogResult.OK)
{
dynamic result = UnZip(ofd.FileName, txtOutFile.Text,"123");
MessageBox.Show(result.msg);
}
}
public dynamic Zip(string[] files, ZipOutputStream outStream, string pwd)
{
try
{
for (int i = 0; i < files.Length; i )
{
if (!File.Exists(files[i]))
{
throw new Exception("文件不存在");
}
using (FileStream fs = File.OpenRead(files[i]))
{
byte[] buffer = new byte[fs.Length];
fs.Read(buffer, 0, buffer.Length);
if (!string.IsNullOrWhiteSpace(pwd))
{
outStream.Password = pwd;
}
ZipEntry ZipEntry = new ZipEntry(Path.GetFileName(files[i]));
outStream.PutNextEntry(ZipEntry);
outStream.Write(buffer, 0, buffer.Length);
}
}
return new { result = true, msg = "压缩成功" };
}
catch (Exception ex)
{
return new { result = true, msg = "压缩失败:" ex.Message };
}
}
public dynamic UnZip(string zipFile, string outPath, string pwd)
{
try
{
if (!Directory.Exists(outPath))
{
Directory.CreateDirectory(outPath);
}
using (ZipInputStream zipInputStream = new ZipInputStream(File.OpenRead(zipFile)))
{
if (!string.IsNullOrWhiteSpace(pwd))
{
zipInputStream.Password = pwd;
}
ZipEntry theEntry;
while ((theEntry = zipInputStream.GetNextEntry()) != null)
{
using (FileStream streamWriter = File.Create(outPath "\\" theEntry.Name))
{
byte[] data = new byte[1024 * 1024];
int dataLength = 0;
while ((dataLength = zipInputStream.Read(data, 0, data.Length)) > 0)
{
streamWriter.Write(data, 0, dataLength);
}
}
}
}
return new { result = true, msg = "解压成功" };
}
catch (Exception ex)
{
return new { result = true, msg = "解压失败:" ex.Message };
}
}
