.NET default ChartArea indexer for Chart component in C++/CLI and .NET 4.0 and later

Question

Hello,

in .NET 3.5 and VS2008sp1  I could use this:

this->chart1->ChartAreas[0]->InnerPlotPosition->Auto = true;

but now, in VS2013 the IntelliSense gives me ERROR that there is only

::default[System::String^]::get instead of Int32 indexer i.e. I must use this sequence

System::Collections::Generic::IEnumerator<System::Windows::Forms::DataVisualization::Charting::ChartArea^>^ ie = this->chart1->ChartAreas->GetEnumerator();
ie->MoveNext();
safe_cast<ChartArea^>(ie->Current)->InnerPlotPosition->Auto = true;

but compiler IS CAPABLE to compile without any error.

Where is problem ? IntelliSense has problem in VS2013 ?  --- as usually ?

of course this code is nice for IntelliSense as well:

System::Collections::Generic::IEnumerator<System::Windows::Forms::DataVisualization::Charting::ChartArea^>^ ie = this->chart1->ChartAreas->GetEnumerator();
ie->MoveNext();
this->chart1->ChartAreas[ ie->Current->Name ]->InnerPlotPosition->Auto = true;

Here is Int32 indexer:  https://msdn.microsoft.com/cs-cz/library/dd468031%28v=vs.110%29.aspx

and here is screenshot:

Can someone give me some explanation ?

Thanks.

Answer 1

If you are interested in a simpler workaround, try this:

Collection<ChartArea^> ^ areas = chart1->ChartAreas;
areas[0]->InnerPlotPosition->Auto = true;

By the way, these classes are not available in .NET 3.5 (according to documentation).
