I am new to C# and I am trying to convert this vba code to C#:

Columns("A:A").Select
Selection.TextToColumns Destination:=Range("A1"),
DataType:=xlDelimited, _
TextQualifier:=xlDoubleQuote, ConsecutiveDelimiter:=False,
Tab:=False, _
Semicolon:=False, Comma:=True, Space:=False, Other:=False,
FieldInfo _
:=Array(Array(1, 1), Array(2, 1), Array(3, 1), Array(4, 1),
Array(5, 1), Array(6, 1), _
Array(7, 1), Array(8, 1), Array(9, 1), Array(10, 1), Array(11,
1), Array(12, 1), Array(13, 1 _
), Array(14, 1), Array(15, 1), Array(16, 1), Array(17, 1),
Array(18, 1)), _
TrailingMinusNumbers:=True

I come up with this:

aRange = excelWorksheet.get_Range("A1",
Missing.Value);
aRange.TextToColumns("A1",
Excel.XlTextParsingType.xlDelimited,
Excel.XlTextQualifier.xlTextQualifierDoubleQuote,
false, false, false, true, false, false,
false, false, false, false, true);

I get an error with the range. I can find several vb examples of this
but no c# using the interop.

Thanks
