C# array of object indexing in matlab

In matlab, I have array of c# objects and I want to select the object on index position 1.

doc.Workbook.Worksheets

ans =

    ExcelWorksheets with properties:

    Count: 3
I tried to use small, curly and square brackets to access the object and I am getting following errors:

Array formation and indexing are not allowed on .NET objects.

 doc.Workbook.Worksheets[1]
                        |
Error: Unbalanced or unexpected parenthesis or bracket.

Use the Item method:

doc.Workbook.Worksheets.Item(1)

It's part of the IList interface which all arrays implement.

Your answer is partially correct. If I execute above statement without placing semicolon in end then I get error.

Try parentheses instead of brackets: doc.Workbook.Worksheets(1)

I tried this approach and was getting following error: Array formation and indexing are not allowed on .NET objects.
