我已安装了SQL，可还是提示：此计算机未安装SQL软件，请安装SQL后再试
代码如下


private void start_Load(object sender, EventArgs e)
        {
            if (exitSQL())
            {
                timer1.Start();

            }
            else
            {
                MessageBox.Show("此计算机未安装SQL软件，请安装SQL后再试", "SQL错误提示", MessageBoxButtons.OK);
                Application.Exit();
            }
        }

        public bool exitSQL()
        {
            bool sqlflag = false;
            ServiceController[] services = ServiceController.GetDevices();
            for (int i = 0; i < services.Length; i++)
            {
                if (services[i].DisplayName.ToString() == "MSSQLSERVER")
                {
                    sqlflag = true;
                }
            }

            return sqlflag;
        }
