Question

我有以下代码来序列化/反序列化DataTable：

    public static byte[] Serialize(DataTable dt)
    {
        System.IO.MemoryStream stream = new System.IO.MemoryStream();
        System.Runtime.Serialization.IFormatter formatter = new System.Runtime.Serialization.Formatters.Binary.BinaryFormatter();
        formatter.Serialize(stream, dt); 
        return stream.GetBuffer(); 
    }


    public static DataTable Deserialize(byte[] buffer) 
    {
        System.IO.MemoryStream stream = new System.IO.MemoryStream(buffer);
        System.Runtime.Serialization.IFormatter formatter = new BinaryFormatter();

        return formatter.Deserialize(stream) as DataTable; 
    }

serialize方法工作正常，但deserialize方法会产生此错误：

  The input stream is not a valid binary format. The starting contents (in bytes) are: 1F-8B-08 ...

我99％肯定我已经让这种方法在过去工作，不知道什么是错的。

你不应该使用GetBuffer()而是使用ToArray()，因为后者确实返回内容而Getbuffer()可以返回未初始化的字节...

将byte []反序列化为DataTable
