检查datagridview C＃行的颜色

Question

I basically want to check if a certain row contains white color then it should not be replaced in the datagridview otherwise if it contains any other color then the text in that row can be replaced but I don't know how to check that condition in this scenario.

This is the code.

private void button9_Click_1(object sender, EventArgs e)
{
  var original = ((DataTable)dataGridView1.DataSource);
  var clone = original.Clone();
  var ordinal = original.Columns["Stringtext"].Ordinal;
  for (int i = 0; i < original.Rows.Count; i++)
  {
     var values = original.Rows[i].ItemArray;
            values[ordinal] = ((values[ordinal].ToString()).ToLower())
                .Replace(textBox6.Text.ToLower(), textBox7.Text);
            clone.Rows.Add(values);
  }
        dataGridView1.DataSource = clone;
        string filterBy;
        filterBy = "Stringtext Like '%" + textBox7.Text + "%'";
        ((DataTable)dataGridView1.DataSource).DefaultView.RowFilter = filterBy;
}

any ideas?

To loop through all cells in the DataGridView and check the background color of the cell you can do something like

for (int c = 0; c < dataGridView.ColumnCount; c++)
{
    for (int r = 0; r < dataGridView.RowCount; r++)
    {
        if (dataGridView.DefaultCellStyle.BackColor != Color.White)
            // Do your update here
    }
}

I hope this helps.
