我正在尝试将我的 MMF 序列化为文件，这是代码：
class MMF {
private const string filename = @"c:\NFS";
private long offset = 0;
private long length = 194;
private byte[] buffer;
public MMF() {
using (var mmf =
MemoryMappedFile.CreateFromFile(filename, FileMode.OpenOrCreate, null, offset + length, MemoryMappedFileAccess.ReadWriteExecute)) {
using (var accessor = mmf.CreateViewAccessor(offset, length, MemoryMappedFileAccess.ReadWriteExecute)) {
buffer = new byte[194];
/*FS fs = new FS();
fs.Files[0].Path = "test";
accessor.WriteArray<byte>(0, buffer, 0, (int)length);*/
accessor.ReadArray<byte>(0, buffer, 0, (int)length);
FS fs = (FS)ToObject(buffer);
Console.WriteLine(fs.Files[0].Path);
}
}
}
private byte[] ToByteArray(object source) {
var formatter = new BinaryFormatter();
using (var stream = new MemoryStream()) {
formatter.Serialize(stream, source);
return stream.ToArray();
}
}
private object ToObject(byte[] source) {
var formatter = new BinaryFormatter();
using (var stream = new MemoryStream(source)) {
formatter.Deserialize(stream);
return stream;
}
}
}
在反序列化部分我收到错误：
mscorlib.dll 中出现“System.Runtime.Serialization.SerializationException”类型的未处理异常
附加信息：二进制流“0”不包含有效的二进制标头 BinaryHeader。可能的原因：无效的流或序列化和反序列化之间的对象版本更改。
如何正确反序列化文件？我的错误在哪里？
谢谢你
