c# - 像写入文件一样写入流，但实际上写入对象

Question

我正在尝试将流写入 ram 而不是文件。我试过这样做:

Stream stream = new MemoryStream();
BinaryFormatter bFormatter = new BinaryFormatter();
bFormatter.Serialize(stream, objectToSerialize);
stream.Close();
return stream;

但是，当我在据称写入流后查看流时，它说“Length = 'stream.Length' throw an exception of type 'System.ObjectDisposedException'”

Answer 1

在获取数据之前不要关闭流，并且不返回流而是返回流的内容:

using (Stream stream = new MemoryStream()) {
  BinaryFormatter bFormatter = new BinaryFormatter();
  bFormatter.Serialize(stream, objectToSerialize);
  return stream.ToArray();
}
