C# equivalent for ByteArrayOutputStream in java
提问by Vaibhav
I have javacode as
我有java代码
ByteArrayOutputStream baos = new ByteArrayOutputStream();
baos.write(tokenBytes);
baos.write(signedData);
byte[] finalout = baos.toByteArray();
where tokenBytes and signedData are byte arrays.In c#I have written as
其中 tokenBytes 和 signedData 是字节数组。在c#我写为
using (MemoryStream stream = new MemoryStream())
{
using (BinaryWriter writer = new BinaryWriter(stream))
{
writer.Write(tokenBytes);
writer.Write(signature);
}
finalBytesToSend = stream.ToArray();
}
where tokenBytes , signature and finaleBytesToSend are byte arrays.
其中 tokenBytes 、 signature 和 finaleBytesToSend 是字节数组。
Is it correct? OR is there any other way to do it?
这是正确的吗？或者有其他方法可以做到吗？

Presumably I assume you are writing a Java-C# serialization scheme. I think there are 3 things you might want to be careful:
据推测，我假设您正在编写 Java-C# 序列化方案。我认为您可能需要注意 3 件事：
- That Java byte array output might contain special deliminator at the end.
- That Java by default using Big-Endian encoding if your data in the byte array wasn't originally just bytes; while C# default is Little Endian encoding.
- That for strings Java is using UTF-16 (Big Endian) and C# UTF-16 by default is Little Endian.
- 该 Java 字节数组输出可能在末尾包含特殊分隔符。
- 如果字节数组中的数据最初不只是字节，那么 Java 默认使用 Big-Endian 编码；而 C# 默认是 Little Endian 编码。
- 对于字符串，Java 使用 UTF-16（Big Endian），C# UTF-16 默认使用 Little Endian。
In my opinion if you are transferring data between Java and C#, you'd better use simply ByteBuffer in Java side and MemoryStream/BinaryReader/BinaryWrite in C# side. Setting UTF-16 Big Endian correctly in C# side, and write your own de-serializer for stuff like int/long/double primitives. That makes it work.
在我看来，如果您在 Java 和 C# 之间传输数据，最好在 Java 端使用 ByteBuffer，在 C# 端使用 MemoryStream/BinaryReader/BinaryWrite。在 C# 端正确设置 UTF-16 Big Endian，并为 int/long/double 基元等内容编写自己的反序列化器。这使它起作用。
