2a451bc049 TSDU: Use Array.Copy for Read functions. 2020-09-02 20:09:51 +02:00
Serge Camille
bd8177d39e Add nullable support throughout the whole library. 
This requires reference types that can be null to be annotated by a ? operator, similar to value types.

This gives the advantage that the compiler can warn against any null dereference exceptions, of which this commits elimits a few.

To make the underlying protocol implementation not any more complicated and to eliminate existing problems, and not that precise error reporting, I replaced some return null statements with explicit Exceptions. This lead to the assumption that those core protocoll functions always return non-null objects if they do not throw, making the PLC code simpler.

Adjust some NotConnected tests to look for explicit PlcException instead of NullReferenceException.

Add new class Types.Dtl by taking the DateTime type and adjusting things.

Also add unit test with binary data calculated by hand. (Need to verify with actual S7 data)

2204ab360c Fix write stringex (#162) 
* Add StringEx.ToByteArray(...)

* Add Serialization.SerializeDataItem(DataItem)

Supports StringEx VarType or offloads to SerializeValue method.

* Use SerializeDataItem in S7WriteMultiple

* Assume string length without header in StringEx.ToByteArray

VarTypeToByteLength already assumed that StringEx declared count for
the number of characters without the header, this now matches that
behavior.

* Add unit tests for StringEx conversions

* Fix incorrect value passed to Encoding.GetBytes

The length must actually be within string limits.
