从二进制文件反序列化具有结构成员的类

我对二进制文件的反序列化结构有问题。我的结构体有另一个结构作为属性：

[Serializable()]
public struct Record : ISerializable
{
    public SensorInfo SensorInfo;
    public List<short[]> Frames;
    public Record(SerializationInfo info, StreamingContext ctxt)
    {
        this.Frames = (List<short[]>)info.GetValue("Frames", typeof(List<short[]>));
        this.SensorInfo = (SensorInfo)info.GetValue("SensorInfo", typeof(SensorInfo));
    }
    public void GetObjectData(SerializationInfo info, StreamingContext ctxt)
    {
        info.AddValue("Frames", this.Frames);
        info.AddValue("SensorInfo", this.SensorInfo);
    }
}

传感器信息结构：

[Serializable]
public struct SensorInfo : ISerializable
{
    public double Frequency;
    public int FramePixelDataLength;
    public int FrameWidth;
    public int FrameHeight;
    public SensorInfo(SerializationInfo info, StreamingContext ctxt)
    {
        this.Frequency = (double)info.GetValue("Frequency", typeof(double));
        this.FramePixelDataLength = (int)info.GetValue("FramePixelDataLength", typeof(int));
        this.FrameWidth = (int)info.GetValue("FrameWidth", typeof(int));
        this.FrameHeight = (int)info.GetValue("FrameHeight", typeof(int));
    }
    public void GetObjectData(SerializationInfo info, StreamingContext ctxt)
    {
        info.AddValue("Frequency ", this.Frequency);
        info.AddValue("FramePixelDataLength ", this.FramePixelDataLength);
        info.AddValue("FrameWidth", this.FrameWidth);
        info.AddValue("FrameHeight", this.FrameHeight);
    }
}

我正在使用以下代码使用序列化程序：

static public class RecordSerializer
{
    static RecordSerializer()
    {
    }
    public static void SerializeRecord(string filename, Record recordToSerialize)
    {
       Stream stream = File.Open(filename, FileMode.Create);
       BinaryFormatter bFormatter = new BinaryFormatter();
       bFormatter.Serialize(stream, recordToSerialize);
       stream.Close();
    }
    public static Record DeSerializeRecord(string filename)
    {
       Record recordToSerialize;
       Stream stream = File.Open(filename, FileMode.Open);
       BinaryFormatter bFormatter = new BinaryFormatter();
       bFormatter.AssemblyFormat = System.Runtime.Serialization.Formatters.FormatterAssemblyStyle.Simple;
       recordToSerialize = (Record)bFormatter.Deserialize(stream);
       stream.Close();
       return recordToSerialize;
    }
}

序列化工作正常，我得到一个输出文件。但是当我尝试反序列化它时，我只收到来自 bFormatter.反序列化和反序列化失败的异常。

Frequency not found.

流不为空，我检查了这个。

感谢您的任何想法。
