get range from excel sheet of separate columns using c#

[kobycool]

hi,

I want to get range of separate columns from sheet in excel.

for example: I want the entire columns: "A", "D", "F"



Can I do it in one line statement? or whether I need to do it in three steps:

sheet1.get_Range("A",...)

sheet1.get_Range("D",...)

sheet1.get_Range("F",...)



Thanks

Koby
