用了近一天的时间研究了c#如何开启sqlserver数据库的服务,起先应用的是c#自带的system.serviceprocess.servicecontorller类,但个人认为它在win7下效果不佳,或许由于个人系统问题,最终决定放弃去选择应用c#的system.diagnostice.process.start方法执行cmd指令,下面我示范开启sqlserver最具代表的两个服务mssqlserver与mssqlserveragent,下面是本人练习写的控制台下的代码,经由多次测试均可成功
using system;
using system.collections.generic;
using system.management;
namespace consoleapplication1
{
class program
{
static void main(string[] args)
{
while (1 == 1)
{
console.write('\n\n 可选操作 : \n\n 1.启动数据库服务 2.停止数据库服务 \n\n 开始执行 : ');
string strquerystate = console.readline();
if (strquerystate.trim() == '1')
{
string strfilepath = getfilepath('start');
system.io.file.appendalltext(strfilepath, getcmdstr('start'), system.text.encoding.getencoding('gb2312'));
system.diagnostics.process.start(strfilepath);
}
else if (strquerystate.trim() == '2')
{
string strfilepath = getfilepath('stop');
system.io.file.appendalltext(strfilepath, getcmdstr('stop'), system.text.encoding.getencoding('gb2312'));
system.diagnostics.process.start(strfilepath);
}
}
}
/// <summary>
/// 操作所需的cmd指令
/// </summary>
/// <param name='statestr'>操作</param>
/// <returns>cmd指令</returns>
private static string getcmdstr(string statestr)
{
string cmdstr = '';
if (statestr.tolower().trim() == 'start')
{
cmdstr = @'@echo. & del %0 & @echo off & @echo.正在启动服务 mssqlserver and mssqlserveragent ...... & '
+ '@echo. & @net start mssqlserver & @net start sqlserveragent & @echo.服务启动完毕!';
}
else if (statestr.tolower().trim() == 'stop')
{
cmdstr = @'@echo. & del %0 & @echo off & @echo.正在停止服务 mssqlserver and mssqlserveragent ...... & '
+ '@echo. & @net stop sqlserveragent & @net stop mssqlserver & @echo.服务停止完毕!';
}
return cmdstr;
}
/// <summary>
/// 获取一个文件是否存在于磁盘
/// </summary>
/// <param name='pathstr'>文件名称</param>
/// <returns>返回可创建文件路径</returns>
private static string getfilepath(string strfilename)
{
string strtem = '';//用于存储要保存文件路径
string[] strpath = new string[] {@'c:\\',@'d:\\',@'e:\\',@'f:\\'};//检测的盘符
strfilename += datetime.now.year.tostring() + datetime.now.month.tostring() + datetime.now.day.tostring()
+ datetime.now.hour.tostring() + datetime.now.minute.tostring() + datetime.now.second.tostring() + datetime.now.millisecond.tostring().trim()+'.cmd';//为防止重复为文件重新命名
foreach (string pathstr in strpath)//循环判断文件目录存在性
{
if (!system.io.directory.exists(pathstr))//判断目录存在
{
continue;
}
else
{
if (system.io.file.exists(pathstr + strfilename))//判断文件存在
{
continue;
}
else
{
strtem = pathstr + strfilename;
break;
}
}
}
return strtem;//返回可建文件路径
}
}
}
