BufferedFileReader & BufferedFileWriter: extending BinaryReader and BinaryWriter using BufferedStream

Hi Olivier,
First, thank you for your helpful post here and I'd like introduce some suggestion that might help to increase the performance of the Read & Write methods (of arrays such as ReadIntArray, ReadFloatArray and WriteIntArray, .... etc.). My suggestion is to make use of the System.Buffer.BlockCopy() that can be used to copy the items from some numeric type array to another one. For example, your ReadIntArray() code might be replaced by:
 

public int[] ReadIntArray(int length)
{
    int[] array = new int[length];
    byte[] bytes = ReadBytes(length * 4);
    System.Buffer.BlockCopy(bytes, 0, array, 0, bytes.Length);
    return array;
}

 

 

and the WriteIntArray() should be replaced by:

 

 

 

 

 

 

 

 

 

 

 

public void Write(int[] array)
{
    byte[] bytes = new byte[4 * array.Length];
    System.Buffer.BlockCopy(bytes, 0, bytes, 0, bytes.Length);
    Write(bytes);
}

 

 

I hope that will help... and thanks again for your great post.
