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：
