I want to merge a range of 3 cells for each row where the first cell and the last cell are set to "", however it does not seem to work for me.

What I have tried:

I tried doing it for all the rows whether the first and third cell are blank or not and it works.

C#

for(int i = 2; i <= 20;i++)
                     {
                        
                       
                         
                            string c = worksheet.Cells[i, 5];
                            worksheet.Range[worksheet.Cells[i , 4], worksheet.Cells[i , 6]].Merge(1);
                          
                            /* currRange.Value2 = worksheet.Cells[i, 5];
                             currRange.Select();
                             currRange.Merge(Missing.Value);*/
                         
                     }

Can you please help out?

Solution 2

Recommended method of doing work from C# was given here: Export datagridview to excel while keeping the formatting[^]:
1. Create a Macro recording of the actions that you wish to perform
2. View the VBA code generated for you
3. Use the VBA code to guide you for writing your C# code

If you follow these steps, and the original answer given, you will easily solve this question.

You're absolutely right! Thanks again and sorry for the disturbance...

It is not a disturbance. Let the macro recorder do all the hard work for you. When recording Excel macros, think about if you require relative or absolute cell reference. By default it is set to absolute. the option is right next to the record macro button.
