将 byte[] 反序列化回 DataTable
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;
}
序列化方法工作正常，但反序列化方法会产生此错误：
The input stream is not a valid binary format. The starting contents (in bytes) are: 1F-8B-08 ...
我 99% 确定我过去已经使用过此方法，但不确定出了什么问题。
I have the following code to serialize /deserialize a 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;
}
The serialize method works fine but the deserialize method produces this error:
The input stream is not a valid binary format. The starting contents (in bytes) are: 1F-8B-08 ...
I am 99% sure I have gotten this method to work in the past, not sure whats wrong.

您不应该使用
GetBuffer()而应使用ToArray()，因为后者实际上返回内容，而Getbuffer()可能返回未初始化的字节...参见

you should not use
GetBuffer()butToArray()since the latter returns really the content whileGetbuffer()could return uninitialized bytes...see
