C# Transpose() method to transpose rows and columns in excel sheet

Question

I want to transpose rows and columns of an excel sheet and save it. I want to use C# transpose() method for this purpose. Can anybody tell how it can be used in C# with exam

Answer 1

your method is part of the Excel object model but included in C# through Visual Studio Tools for Office / Excel DNA / Managed XLL etc

Object[,] transposedRange = (Object[,])xlApp.WorksheetFunction.Transpose(rng.Value2);

Then paste the transposedRange back into Excel:

xlApp.ActiveSheet.Range("A1").Resize(transposedRange.GetUpperBound(0), transposedRange.GetUpperBound(1)) = transposedRange;
