C# - Implement Column Self-naming From Its Index?

I wish to be able to instantiate my Cell class while naming the cell instance with such name as "A", "B", "C", etc. just like in an Excel spreadsheet.

I have my Cell class like so:

public class Cell {
public Cell(Range nativeCell) {
NativeCell = nativeCell;

[Code].....

I would need to generate a name based on the alphabetic letters and double and triple them once I encounter the last alphabet letter 'Z'. The algorithm would have to generate the letters that I would concatenate with the rowIndex value that would result to this naming strategy such as Excel.

The letters would be:

A, B, C, D...Z, AA, AB, AC...AZ, BA, BB, BC...BZ, CA...XAA, XAB, XAC...

While we clearly know that colIndex value 1 will definitely designate column "A", value 2 = "B", value 3 = "C", etc.

My problem is particularly when we double the letters.

how I could achieve this in the simplest possible form?
