C console program to open and close the SQLServer service code sharing

Took nearly C # 1 day time studied how to unlock SqlServer database service, the first application is the System C #. The ServiceProcess. ServiceContorller classes, but personally think it under win7 the effect not beautiful, perhaps because of personal system, finally decided to give up to choose C # system. diagnostice. process. start method to execute commands cmd, below I open SqlServer demonstration the two most representative service mssqlserver and mssqlserveragent, here is my practice writing control The code produced under the platform can be successfully tested for many times

using System;
using System.Collections.Generic;
