通过C#启动SQL Server

Question

当我启动我的PC时,Sql Server(SQLExpress)没有运行,它在我尝试在Visual Studios 2010中编译我的程序时启动.

是否可以通过C#启动它？我的问题是,如果我在没有Visual Studios的情况下使用.exe,它会告诉我Sql Server没有运行.

Answer 1

我会将Sql Server Windows服务的启动模式更改为自动.但你也可以在c#中做到这一点,但我不推荐它.还有其他问题,如访问安全性等.

        System.Diagnostics.Process process = new System.Diagnostics.Process();
        process.StartInfo.FileName = "net start \"Sql Server (SQLEXPRESS)\"";
        process.Start();

Sql Server(SQLEXPRESS)是您的服务名称.

以下是如何在C#中使用SMO:

using System;
using System.Collections;
using System.Collections.Generic;
using System.Data;
using System.Diagnostics;
using Microsoft.SqlServer.Management.Smo;
using Microsoft.SqlServer.Management.Smo.Wmi;
using Microsoft.SqlServer.Management.Common;

static class SQLStart
{
    public static void StartSQLService()
    {
        //Declare and create an instance of the ManagedComputer object that represents the WMI Provider services.
        ManagedComputer mc = default(ManagedComputer);
        mc = new ManagedComputer();

        //Iterate through each service registered with the WMI Provider.
        Service svc = default(Service);
        foreach ( svc in mc.Services) {
            Console.WriteLine(svc.Name);
        }

        //Reference the Microsoft SQL Server service.
        svc = mc.Services("MSSQLSERVER");

        //Stop the service if it is running and report on the status continuously until it has stopped.
        if (svc.ServiceState == ServiceState.Running) {
            svc.Stop();

            Console.WriteLine(string.Format("{0} service state is {1}", svc.Name, svc.ServiceState));
            while (!(string.Format("{0}", svc.ServiceState) == "Stopped")) {
                Console.WriteLine(string.Format("{0}", svc.ServiceState));
                svc.Refresh();
            }
            Console.WriteLine(string.Format("{0} service state is {1}", svc.Name, svc.ServiceState));
            //Start the service and report on the status continuously until it has started.
            svc.Start();
            while (!(string.Format("{0}", svc.ServiceState) == "Running")) {
                Console.WriteLine(string.Format("{0}", svc.ServiceState));
                svc.Refresh();
            }
            Console.WriteLine(string.Format("{0} service state is {1}", svc.Name, svc.ServiceState));

        } else {
            Console.WriteLine("SQL Server service is not running.");
        }
    }
}

这只是MS的VB.net示例的转换.这一切都在这里解释:http://msdn.microsoft.com/en-us/library/ms162139(v = sql.90).aspx
