我在上面的图片上有这个datagridview,并且“Joe”名称是重复的 如何通过c#突出显示或将颜色更改为红色以获取重复值,例如“Joe”? 感谢:)

你可以试试这个:
//using System.Linq;
private void button1_Click(object sender, EventArgs e)
{
var rows = dataGridView1.Rows.OfType<DataGridViewRow>()
.Reverse().Skip(1);//ignore the last empty line
var dupRos = rows.GroupBy(r => r.Cells["name"].Value.ToString())
.Where(g => g.Count() > 1)
.SelectMany(r => r.ToList());
foreach (var r in dupRos)
r.DefaultCellStyle.BackColor = Color.Red;
foreach (var r in rows.Except(dupRos))
r.DefaultCellStyle.BackColor = Color.White;
}
