> .NET: support Multidimensional Arrays in binary serializer
> ----------------------------------------------------------
>
> Key: IGNITE-6896
> URL: https://issues.apache.org/jira/browse/IGNITE-6896
> Project: Ignite
> Issue Type: Improvement
> Security Level: Public(Viewable by anyone)
> Components: platforms
> Affects Versions: 2.3
> Reporter: Alexey Popov
>
> It is found that legacy 2D, 3D, etc. are not working in BinarySerializer.
> Sample reproducer:
> {code:java}
> [Test]
> public void TestXX()
> {
> var array2D = new float[32, 32];
> var res = TestUtils.SerializeDeserialize(array2D);
> Assert.AreEqual(array2D, res);
> }
> {code}
> BTW, please note that 2D array in Java (a[2][2]) is just a jugged array:
> obj = {byte[2][]@1928}
> 0 = {byte[2]@1974}
> 1 = {byte[2]@1975}
