Excel c# convert cell to percentage

Question

Hello. I need to convert a cell with a double to a precentage. I used a macro in excel and it says:

Range("B5").Select
Selection.Style = "Percent"

When I do this in c#, it doesn't work:

Excel.Range procentRange = xlWorksheet.get_Range("A1","A1");
procentRange.Style = "Percent";

Anybody knows how to do this?

Answer 1

Try using Excel.Range.NumberFormat instead of Excel.Range.Style

Answer 2

I've found the anwser with help of JN Web

Excel.Range procentRange = xlWorksheet.get_Range("A1","A1");    
procentRange.NumberFormat = "###,##%";

So first you need a range, then set the decimals and add "%" -> automatically a 100 time multiplication
