C# 常用方法扩展及封装记录

1、对象转为byte[] 数据

/// <summary> /// 将对象转化为字节数字 /// </summary> /// <param name="obj">需要转化对象</param> /// <returns></returns> public static byte[] ConvertToBytes(this object obj) {     using (var stream = new MemoryStream())     {         var formatter=new BinaryFormatter();         formatter.Serialize(stream,obj);         return stream.GetBuffer();     } } 

2、对象转为Stream类型

/// <summary> /// 对象转为数据流 /// </summary> /// <param name="obj">需要转化的对象</param> /// <returns></returns> public static MemoryStream ConvertToStream(this object obj) {     using (var stream = new MemoryStream())     {         var formatter = new BinaryFormatter();         formatter.Serialize(stream, obj);         return stream;     } }
