您可以處理DataGridView.CellPainting事件，以確定要customi細胞澤。

private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e) 
{ 
// We are interested in handling the values in the "Description" column only.. 
if (e.ColumnIndex == DescriptionDataGridViewTextBoxColumn.Index) 
{ 
    string description="something"; 
    if (e.Value != null) 

    { 
     if (e.Value.ToString()==description) 
     { 
      e.CellStyle.ForeColor = e.CellStyle.BackColor; 
      e.CellStyle.SelectionForeColor = e.CellStyle.SelectionBackColor; 
     } 
    } 
} 
}
