Question

Programmatically Changing SQL Server Settings

To set up a network connection between a C # client application and SQL Server 2008 R2, I know what needs to be done manually, my problems are how to do the following steps in C # code!

• Set TCP / IP Enabled for a server instance, for example MSSQLSERVERR2.

• Reboot my SQL Server engine.

  I can perform other steps of SQL queries:

• Add user and give administrator permission.

  CREATE LOGIN momtahen 
  WITH PASSWORD = '123'
  
  EXEC master..sp_addsrvrolemember @loginame = N'momtahen', 
                                   @rolename = N'sysadmin'
  

• Set Mixed Authentication Mode for my SQL Server.

  EXEC xp_instance_regwrite N'HKEY_LOCAL_MACHINE', 
  N'Software\Microsoft\MSSQLServer\MSSQLServer', N'LoginMode', REG_DWORD, 2
  

I need C # code or an SQL query that I could execute using C #.

Also I have to mention that I saw the following question and do not help!

• tcp\ip sql-, script ()
• SQL Express script
• TCP SQL Server 2005 2008?
