Equivalent of Java's “ByteBuffer.putType()” in

2019-04-11 18:01发布

问题:

I am trying to format a byte array in C#, by porting a code from Java. In Java, the methods "buf.putInt(value);", buf.putShort, buf.putDouble, (and so forth) are used. However I don't know how to port this to C#. I have tried the MemoryStream class, but there is no method to put a specific type at the end of the byte array.

Question: What is the equivalent of Java's "ByteBuffer.putType(value)" in C#? Thanks!

回答1:

You can use a BinaryWriter and your MemoryStream:

MemoryStream stream = new MemoryStream();
using (BinaryWriter writer = new BinaryWriter(stream))
{
    writer.Write(myByte);
    writer.Write(myInt32);
    writer.Write("Hello");
}

byte[] bytes = stream.ToArray();

Try the BinaryWriter class:

using (var binaryWriter = new BinaryWriter(...))
{
    binaryWriter.Write(323);
    binaryWriter.Write(3487d);
    binaryWriter.Write("Hello");
}

You'll be wanting to use the BitConverter class. The main difference is that these methods return an array of bytes instead of altering an existing array.

(This is a replacement for the specific methods mentioned; for a replacement of the entire ByteBuffer class, see the other replies.)
