Question

I need to get the the highest ColumnIndex among SelectedCells in a DataGridView.

int i = theHighestColumnIndexAmongSelectedCells.

Or

foreach (DataGridViewCell cell in dgv.SelectedCells)  
if cell.ColumnIndex is theHighest  
int i = cell.ColumnIndex.  

How might I do this?

Answer 1

The easiest way it to use the LINQ Max() function:

int max = dgv.SelectedCells.Cast<DataGridViewCell>().Max(c => c.ColumnIndex);
