求XML壓縮和解壓縮源碼，在線等。。。

//如題，只要兩個方法的源碼就可以。

//1.

public string XmlPress(string stra)

{

  //...這個是壓縮代碼

  MemoryStream inStream = new MemoryStream(); 

  StreamWriter writer = new StreamWriter(inStream);

  writer.Write(stra); 

  writer.Flush();

  writer.Close();

  GZipStream gzOut = new GZipStream(inStream, CompressionMode.Compress);

  StreamWriter sw = new StreamWriter(gzOut);

  sw.Write(stra);

  StreamReader sr = new StreamReader(gzOut);

  StringBuilder s = new StringBuilder(sr.ReadToEnd);

  sw.Close();

  gzOut.Close();

  return s.ToString();

}

//2.

public string XmlDePress(string strc)

{

  //...這個是解壓縮代碼

  MemoryStream inStream = new MemoryStream(); 

  StreamWriter writer = new StreamWriter(inStream);

  writer.Write(strc); 

  writer.Flush();

  writer.Close();

  GZipStream gzOut = new GZipStream(inStream, CompressionMode.DeCompress);

  StreamWriter sw = new StreamWriter(gzOut);

  sw.Write(strc);

  StreamReader sr = new StreamReader(gzOut);

  StringBuilder s = new StringBuilder(sr.ReadToEnd);

  sw.Close();

  gzOut.Close();

  return s.ToString();

}
