protobuf对象二进制序列化存储(详解)

首先下载protobuf库，可以用nuget。

demo：

using system;

namespace tools
{
  public class bufhelp
  {
    /// <summary>
    /// 对象锁
    /// </summary>
    private readonly static object locker = new object();
    ///// <summary>
    ///// 读写分离锁
    ///// </summary>
    ///// <remarks>aaaaa</remarks>
    //private static readerwriterlockslim rwl = new readerwriterlockslim();

    /// <summary>
    /// 序列化-表字段业务信息
    /// </summary>
    public static bool protobufserialize<t>(t model, string filename) where t : class
    {
      try
      {
        string binpath = config.keycenter.keybasedirectory + @"config\";

        if (!system.io.directory.exists(binpath))
          system.io.directory.createdirectory(binpath);

        lock (locker)
        {
          using (var file = system.io.file.create(binpath + filename))
          {
            protobuf.serializer.serialize<t>(file, model);
            return true;
          }
        }
      }
      catch
      {
        return false;
      }
    }

    public static t protobufdeserialize<t>(string filename) where t : class
    {
      var dbpath = config.keycenter.keybasedirectory + @"config\" + filename;

      if (system.io.file.exists(dbpath))
      {
        lock (locker)
        {
          using (var file = system.io.file.openread(dbpath))
          {
            var result = protobuf.serializer.deserialize<t>(file);
            return result;
          }
        }
      }

      return default(t);
    }
  }
}/// <summary>
    /// 序列化
    /// </summary>
    public static string serialize<t>(t t) where t : class
    {
      using (memorystream ms = new memorystream())
      {
        protobuf.serializer.serialize<t>(ms, t);
        return encoding.utf8.getstring(ms.toarray());
      }
    }
    /// <summary>
    /// 反序列化
    /// </summary>
    public static t deserialize<t>(string content) where t : class
    {
      using (memorystream ms = new memorystream(encoding.utf8.getbytes(content)))
      {
        t t = protobuf.serializer.deserialize<t>(ms);
        return t;
      }
    }
