Answer 1

   DataGridViewCellStyle style;
style = new DataGridViewCellStyle();
            style.BackColor = Color.Red;
            for (int j = 0; j < DGVAnalyse.Rows.Count; j++)
            {
                if (DGVAnalyse.Rows[j].Cells[4].Value.toints() != DGVAnalyse.Rows[j].Cells[5].Value.toints())
                {
                    DGVAnalyse.Rows[j].DefaultCellStyle = style;
}
}
是winform的datagridview

private void dataGridView1_RowPrePaint(object sender, DataGridViewRowPrePaintEventArgs e) 
{ 
if (e.RowIndex >= dataGridView1.Rows.Count - 1) 
return; 
DataGridViewRow dgr = dataGridView1.Rows[e.RowIndex]; 
try 
{ 
//dgr.Cells[0]是当前性别列的索引值，用以确定判断哪一列的值 
if (dgr.Cells[0].Value.ToString() == "男") 
{ 
//定义画笔，使用颜色是深灰。 
using (SolidBrush brush = new SolidBrush(Color.DarkGray)) 
{ 
//利用画笔填充当前行 
e.Graphics.FillRectangle(brush, e.RowBounds); 
//将值重新写回当前行。 
e.PaintCellsContent(e.ClipBounds); 
e.Handled = true; 
} 
} 
} 
catch (Exception ex) 
{ 
MessageBox.Show(ex.Message); 
} }

        {
            if (e != null && e.RowIndex > -1)
            {
                DataGridViewRow dr = this.dataGridView1.Rows[e.RowIndex];
                string i= dr.Cells[""].Value;

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
         //鼠标移到GridView某一行如何改变该行的背景色   
         if (e.Row.RowIndex > -1 && e.Row.RowType == DataControlRowType.DataRow)
       {
        e.Row.Attributes.Add("onmouseover", "this.style.backgroundColor='#ccccff'");
        e.Row.Attributes.Add("onmouseout", "this.style.backgroundColor='#ffffff'");
