解答

 public override (bool ok, string msg) Excute()
{
    var path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory,
        $@"Logs\Info\{DateTime.Now.ToString("yyyy-MM-dd")}.log");
    if (File.Exists(path))
    {
        FileStream fs = new FileStream(path, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
        int fsLen = (int)fs.Length;
        byte[] heByte = new byte[fsLen];
        _ = fs.Read(heByte, 0, heByte.Length);
        var log = System.Text.Encoding.GetEncoding("GB2312").GetString(heByte);
        return (true, log);
    }
    return (true, $"没有找到日志文件{path}");
}
