You have to change endianess:

 bb.order(ByteOrder.LITTLE_ENDIAN)

Java stores things internally as Big Endian, while .NET is Little Endian by default.

Also there is difference in signed and unsigned between Java and .NET. Java uses signed bytes, C# uses unsigned. You will have to change that as well.

Basically, that is why you are seeing -106 ( 150 - 256 )

You will have to do something like the utility method below:

public static void putUnsignedInt (ByteBuffer bb, long value)
    {
       bb.putInt ((int)(value & 0xffffffffL));
    }

Note that value is long.
