如何使用BinaryWriter获取写入字节的长度？

Question

Considering a simple BinaryWriter procedure:

using (BinaryWriter writer = new BinaryWriter(File.Open(fileName, FileMode.Create)))
        {
            writer.Write(10000);
            writer.Write("Temp");
            writer.Write(30);
            writer.Write(50.6);
        }

Now, how can I get the total number of written bytes by the BinaryWriter? And how to append this amount to the current writer object, eg writer.Write(totalNumberAsBytes)

Answer 1

Have you tried writer.BaseStream.Length ? This should be the amount of bytes in the stream.
