C#实现解压GZip文件的方法

本文实例讲述了C#实现解压GZip文件的方法。分享给大家供大家参考。具体实现方法如下：

public void ungzip(string path, string decomPath, bool overwrite)
{
 //for overwriting purposes
 if (File.Exists(decomPath))
 {
if (overwrite)
{
  File.Delete(decomPath);
}
else
{
  throw new IOException("The decompressed path you specified already exists and cannot be overwritten.");
}
 }
 //create our file streams
 GZipStream stream = new GZipStream(new FileStream(path, FileMode.Open, FileAccess.ReadWrite), CompressionMode.Decompress);
 FileStream decompressedFile = new FileStream(decomPath, FileMode.OpenOrCreate, FileAccess.Write);
 //data represents a byte from the compressed file
 //it's set through each iteration of the while loop
 int data;
 while ((data = stream.ReadByte()) != -1) //iterates over the data of the compressed file and writes the decompressed data
 {
decompressedFile.WriteByte((byte)data);
 }
 //close our file streams
 decompressedFile.Close();
 stream.Close();
}

希望本文所述对大家的C#程序设计有所帮助。
