DataGridView Get Text From Specific Column Only Help Needed

Question

I have a datagridview that is populated with 4 columns and multiple rows of data. I want to iterate through the datagridview and get the cell value from A SPECIFIC COLUMN ONLY, since i need this data to pass into a method.

Here is my code:

foreach (DataGridViewRow row in this.dataGridView2.Rows)
{                            
    foreach (DataGridViewCell cell in row.Cells)
    {
        if (cell.Value == null || cell.Value.Equals(""))
        {
            continue;
        }

        GetQuestions(cell.Value.ToString());

    }
}

This just seems to go through all the cells however i need to be able to specify something like:

foreach (DataGridViewRow row in this.dataGridView2.Rows)
{                            
    foreach (DataGridViewCell cell in row.Cells[2])//Note specified column index
    {
        if (cell.Value == null || cell.Value.Equals(""))
        {
            continue;
        }
        GetQuestions(cell.Value.ToString());
    }
}

Answer 1

Don't you just want to remove the inner foreach loop? Or have I missed something?

foreach (DataGridViewRow row in this.dataGridView2.Rows)
{                            
    DataGridViewCell cell = row.Cells[2]; //Note specified column index
    if (cell.Value == null || cell.Value.Equals(""))
    {
        continue;
    }

    GetQuestions(cell.Value.ToString());
}

Answer 2

Perhaps you could check the ColumnIndex? Would still loop through all the cells though.

if (cell.Value == null || cell.Value.Equals("") || cell.ColumnIndex != 2)
{
    continue;
}

Answer 3

foreach (DataGridViewRow row in this.dataGridView2.Rows)
        {
            DataGridViewCell cell = row.Cells["foo"];//Note specified column NAME
            {
                if (cell != null && (cell.Value != null || !cell.Value.Equals("")))
                {
                    GetQuestions(cell.Value.ToString());
                }
            }
        }
