C#读写通达信股票软件二进制dat文件

代码如下：

/// <summary>
/// 添加自定义数据
/// </summary>
/// <param name="file_path">文件路径,此文件为二进制dat文件</param>
/// <returns></returns>
private string AddSignal(string file_path)

// 如果文件不存在则创建
if (!File.Exists(file_path))
{
using (FileStream file = new FileStream(file_path, FileMode.Create))
{

}
}

// 数据结构说明
// 数据号(4)+类型(4)+数据(48)+校验位(4)
// 类型：外部 00 00 00 00 序列 01 00 00 00
// 数据：48位，每一个十进制数占两位，每个十进制数独立分割存储
// 校验位：校验算法不清楚，已测试过Modbus校验、LRC校验、和校验、异或校验，皆不是。

// 读取历史文件数据
var history_data = "";
FileStream fs = new FileStream(file_path, FileMode.Open);
