how to read data from one column of datagridview

Question

I want to read data from one column of datagridview. My datagridview contains many columns but I want to read all cells but only from one column. I read all columns using this code:

foreach (DataGridViewColumn col in dataGridView1.Columns)
        col.Name.ToString();

But I want to read all cell from particular column.

Answer 1

Maybe this helps too. To get one cell:

string data = (string)DataGridView1[iCol, iRow].Value;

Then you can simply loop rows and columns.

Answer 2

Try this

string data = string.Empty;
int indexOfYourColumn = 0;
foreach (DataGridViewRow row in dataGridView1.Rows)
   data = row.Cells[indexOfYourColumn].Value;
