根据条件设置颜色

public Form1()         {             InitializeComponent();             LoadData();
        }
        private void LoadData()         {             DataTable tblDatas = new DataTable();             tblDatas.Columns.Add("ID", Type.GetType("System.Int32"));
            tblDatas.Columns.Add("Name", Type.GetType("System.String"));             tblDatas.Columns.Add("Version", Type.GetType("System.String"));             tblDatas.Columns.Add("Age", Type.GetType("System.String"));             tblDatas.Rows.Add(new object[] { 1, "a", "b", "12" });             tblDatas.Rows.Add(new object[] { 2, "a", "b", "15" });             tblDatas.Rows.Add(new object[] { 3, "a", "b", "30" });             tblDatas.Rows.Add(new object[] { 4, "a", "b", "25" });             tblDatas.Rows.Add(new object[] { 5, "a", "b", "30" });
            dataGridView1.DataSource = tblDatas;         }
private void dataGridView1_CellPainting(object sender, DataGridViewCellPaintingEventArgs e)         {             if (e.RowIndex > -1)             {                 int intGrade = Convert.ToInt32(this.dataGridView1.Rows[e.RowIndex].Cells["dgvAge"].Value);                 if (intGrade ==30)                 {                     dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Red;                 }                 else if(intGrade==25)                 {                     dataGridView1.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.Brown;                 }             }         }

效果图如下：
