在datagridview当鼠标移到某行时，该行改变颜色

private void dgvProjectInfo_CellMouseMove(object sender, DataGridViewCellMouseEventArgs e)
        {
            if  (e.RowIndex >= 0)
            {
                if (e.RowIndex != -1 && e.ColumnIndex != -1)
                {
                    this.dgvProjectInfo.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.LightSkyBlue;
                }
            }

        }

        private void dgvProjectInfo_CellMouseLeave(object sender, DataGridViewCellEventArgs e)
        {
            if (e.RowIndex >= 0)
            {
                if (e.RowIndex != -1 && e.ColumnIndex != -1)
                {
                    this.dgvProjectInfo.Rows[e.RowIndex].DefaultCellStyle.BackColor = System.Drawing.Color.WhiteSmoke;

                }
                this.dgvProjectInfo.Rows[e.RowIndex].DefaultCellStyle.BackColor = Color.White;

            }
        }
