C#启动停止SQL数据库服务

方法一：在命令行里填写命令：net start/stop mssqlserver

方法二：通过C#代码实现；
 using System; using System.Windows.Forms; using System.ServiceProcess; class Test : Form { Test() { //启动按钮； Button btn1 = new Button(); btn1.Parent = this; btn1.Text = "启动 SQL Server"; btn1.Tag = "START"; btn1.Top=50; btn1.Left = 20; btn1.Width = 120; btn1.Click += new EventHandler(BtnClick); //标题； Label la=new Label (); la.Text="C#启动SQL服务"; la.ForeColor=System .Drawing.Color.Green; la.Left=100; la.Top=20; la.Parent=this; //关闭按钮； Button btn2 = new Button(); btn2.Parent = this; btn2.Text = "停止 SQL Server"; btn2.Tag = "STOP"; btn2.Left = btn1.Right + 10; btn2.Top=50; btn2.Width = 120; btn2.Click += new EventHandler(BtnClick); this.Text="C#启动SQL服务"; } void BtnClick(object sender, EventArgs e) { string s = (sender as Button).Tag.ToString(); ServiceController sc = new ServiceController("MSSQLSERVER"); if (s == "START" && sc.Status.Equals(ServiceControllerStatus.Stopped)) { sc.Start(); MessageBox.Show("SQL数据库服务启动成功！","提示信息"); } if (s == "STOP" && !sc.Status.Equals(ServiceControllerStatus.Stopped)) { sc.Stop(); MessageBox.Show("SQL数据库服务已经关闭！","提示信息"); } } static void Main() { Application.Run(new Test()); } }

效果如图：
