C#中压缩字符串

使用以下代码进行压缩和解压 /// <summary> /// 利用ICSharpCode压缩 /// </summary> /// <param name="param"></param> /// <returns></returns> public static string IC_Compress(string param) { byte[] data = System.Text.Encoding.UTF8.GetBytes(param); //byte[] data = Convert.FromBase64String(param); MemoryStream ms = new MemoryStream(); Stream stream = new ICSharpCode.SharpZipLib.BZip2.BZip2OutputStream(ms); try { stream.Write(data, 0, data.Length); } finally { stream.Close(); ms.Close(); } return Convert.ToBase64String(ms.ToArray()); } /// <summary> /// 利用ICSharpCode解压 /// </summary> /// <param name="param"></param> /// <returns></returns> public static string IC_decompress(string param) { string commonString=""; byte[] buffer=Convert.FromBase64String(param); MemoryStream ms = new MemoryStream(buffer); Stream sm = new ICSharpCode.SharpZipLib.BZip2.BZip2InputStream(ms); //这里要指明要读入的格式，要不就有乱码 StreamReader reader = new StreamReader(sm,System.Text.Encoding.UTF8); try { commonString=reader.ReadToEnd(); } finally { sm.Close(); ms.Close(); } return commonString; }
