C#項(xiàng)目中較多使用了序列化和反序列化,較為常用的序列化和反序列化操作有二進(jìn)制流,JSON,XML等,現(xiàn)在介紹一下.net中二進(jìn)制流的序列化和反序列化操作方法:

1.將對(duì)象序列化為二進(jìn)制流:
/// <summary>
/// 將對(duì)象序列化為byte[]
/// 使用IFormatter的Serialize序列化
/// </summary>
/// <param name="obj">需要序列化的對(duì)象</param>
/// <returns>序列化獲取的二進(jìn)制流</returns>
public static byte[] FormatterObjectBytes(object obj)
{
if(obj==null)
throw new ArgumentNullException("obj");
byte[] buff;
try
{
using (var ms = new MemoryStream())
{
IFormatter iFormatter = new BinaryFormatter();
iFormatter.Serialize(ms, obj);
buff = ms.GetBuffer();
}
}
catch (Exception er)
{
throw new Exception(er.Message);
}
return buff;
}2.將對(duì)象轉(zhuǎn)為二進(jìn)制文件,并保存到指定的文件中:
/// <summary>
/// 將對(duì)象轉(zhuǎn)為二進(jìn)制文件,并保存到指定的文件中
/// </summary>
/// <param name="name">文件路徑</param>
/// <param name="obj">待存的對(duì)象</param>
/// <returns></returns>
public static bool BinaryFileSave(string name,object obj)
{
Stream flstr=null;
BinaryWriter binaryWriter=null;
try
{
flstr = new FileStream(name, FileMode.Create);
binaryWriter = new BinaryWriter(flstr);
var buff = FormatterObjectBytes(obj);
binaryWriter.Write(buff);
}
catch (Exception er)
{
throw new Exception(er.Message);
}
finally
{
if (binaryWriter != null) binaryWriter.Close();
if (flstr != null) flstr.Close();
}
return true;
}3.將byte[]反序列化為對(duì)象:
/// <summary>
/// 將byte[]反序列化為對(duì)象
/// 使用IFormatter的Deserialize發(fā)序列化
/// </summary>
/// <param name="buff">傳入的byte[]</param>
/// <returns></returns>
public static object FormatterByteObject(byte[] buff)
{
if(buff==null)
throw new ArgumentNullException("buff");
object obj;
try
{
using (var ms = new MemoryStream())
{
IFormatter iFormatter = new BinaryFormatter();
obj = iFormatter.Deserialize(ms);
}
}
catch (Exception er)
{
throw new Exception(er.Message);
}
return obj;
}4.將對(duì)象序列化為byte[]:
/// <summary>
/// 將對(duì)象序列化為byte[]
/// 使用Marshal的StructureToPtr序列化
/// </summary>
/// <param name="obj">需序列化的對(duì)象</param>
/// <returns>序列化后的byte[]</returns>
public static byte[] MarshalObjectByte(object obj)
{
if(obj==null)
throw new ArgumentNullException("obj");
byte[] buff;
try
{
buff = new byte[Marshal.SizeOf(obj)];
var ptr = Marshal.UnsafeAddrOfPinnedArrayElement(buff, 0);
Marshal.StructureToPtr(obj, ptr, true);
}
catch (Exception er)
{
throw new Exception(er.Message);
}
return buff;
}5.將byte[]序列化為對(duì)象:
/// <summary>
/// 將byte[]序列化為對(duì)象
/// </summary>
/// <param name="buff">被轉(zhuǎn)換的二進(jìn)制流</param>
/// <param name="type">轉(zhuǎn)換成的類名</param>
/// <returns></returns>
public static object MarshalByteObject(byte[] buff, Type type)
{
if(buff==null)
throw new ArgumentNullException("buff");
if(type==null)
throw new ArgumentNullException("type");
try
{
var ptr = Marshal.UnsafeAddrOfPinnedArrayElement(buff, 0);
return Marshal.PtrToStructure(ptr, type);
}
catch (Exception er)
{
throw new Exception(er.Message);
}
}6.將文件轉(zhuǎn)換為byte數(shù)組:
/// <summary>
/// 將文件轉(zhuǎn)換為byte數(shù)組
/// </summary>
/// <param name="path">文件地址</param>
/// <returns>轉(zhuǎn)換后的byte[]</returns>
public static byte[] FileObjectBytes(string path)
{
if(string.IsNullOrEmpty(path))
throw new ArgumentNullException("path");
if (!File.Exists(path)) return new byte[0];
try
{
var fi = new FileInfo(path);
var buff = new byte[fi.Length];
var fs = fi.OpenRead();
fs.Read(buff, 0, Convert.ToInt32(fs.Length));
fs.Close();
return buff;
}
catch (Exception er)
{
throw new Exception(er.Message);
}
}7.將byte[]轉(zhuǎn)換為文件并保存到指定的地址:
/// <summary>
/// 將byte[]轉(zhuǎn)換為文件并保存到指定的地址
/// </summary>
/// <param name="buff">需反序列化的byte[]</param>
/// <param name="savePath">文件保存的路徑</param>
/// <returns>是否成功</returns>
public static string FileByteObject(byte[] buff, string savePath)
{
if(buff==null)
throw new ArgumentNullException("buff");
if(savePath==null)
throw new ArgumentNullException("savePath");
if (File.Exists(savePath)) return "文件名重復(fù)";
try
{
var fs = new FileStream(savePath, FileMode.CreateNew);
var bw = new BinaryWriter(fs);
bw.Write(buff, 0, buff.Length);
bw.Close();
fs.Close();
}
catch (Exception er)
{
throw new Exception(er.Message);
}
return "保存成功";
}8.將圖片序列化為二進(jìn)制流:
/// <summary>
/// 將圖片序列化為二進(jìn)制流
/// </summary>
/// <param name="imgPath">圖片路徑</param>
/// <returns>序列化后的二進(jìn)制流</returns>
public static byte[] SetImgToBytes(string imgPath)
{
if(string.IsNullOrEmpty(imgPath))
throw new ArgumentNullException(imgPath);
try
{
byte[] byteData;
using (var file=new FileStream(imgPath,FileMode.Open,FileAccess.Read))
{
byteData=new byte[file.Length];
file.Read(byteData, 0, byteData.Length);
file.Close();
}
return byteData;
}
catch (Exception er)
{
throw new Exception(er.Message);
