             Summary: .NET: Improve array access in IBinaryReader and IBinaryRawReader
                 Key: IGNITE-5904
                 URL: https://issues.apache.org/jira/browse/IGNITE-5904
             Project: Ignite
          Issue Type: Improvement
          Components: platforms
            Reporter: Pavel Tupitsyn


Currently the only way to work with array fields is reading them entirely into a new instance:
{code}
byte[] ReadByteArray();
{code}

This does not allow reusing existing array (array pooling) or reading only a part of the data (random access).

Many .NET APIs provide an approach where existing array is used with index and offset ({{Array.Copy}}, {{Socket.Receive}}, etc). 

We can do a similar thing for *arrays of fixed-size elements*:
{code}
int ReadByteArray(byte[] dest, int destOffset, int srcOffset, int count);
{code}
