Execute .bat file vb.net - vb.net

Question

I need to install my win service. With installUtil it is just few lines of code.
#ECHO OFF
REM The following directory is for .NET 2.0
set DOTNETFX2=%SystemRoot%\Microsoft.NET\Framework\v2.0.50727
set PATH=%PATH%;%DOTNETFX2%
echo Installing MyService...
echo ---------------------------------------------------
InstallUtil /i MyService.exe
echo ---------------------------------------------------
echo Done.
pause
But my thoughts are without creating .bat file and then runing it.
Is there any way i can ".execute" those lines of code above without creating .bat file runing it and then deleting it ?.
I will need to dynamically create this code every time because i need to enter the username/password depending what user entered on .net form.

You could start cmd and doing it in one line via it's arguments:
Process.Start("cmd.exe", "/k set DOTNETFX2=%SystemRoot%\Microsoft.NET\Framework\v2.0.50727 & set PATH=%PATH%;%DOTNETFX2% & InstallUtil /i MyService.exe")
And if you want it to show the text you wrote and to "pause" (stay open):
Process.Start("cmd.exe", "/k set DOTNETFX2=%SystemRoot%\Microsoft.NET\Framework\v2.0.50727 & set PATH=%PATH%;%DOTNETFX2% & echo Installing MyService... & echo --------------------------------------------------- & InstallUtil /i MyService.exe & echo --------------------------------------------------- & echo Done. & pause")
Commands are separated by " & ".

I know it's been a month since you first asked this, but I recently came up with a pretty good solution to this - only using this simple VB.NET code:
Public Sub InstallService(ByVal ServicePath As String)
Dim InstallUtilPath As String = IO.Path.Combine(System.Runtime.InteropServices.RuntimeEnvironment.GetRuntimeDirectory(), "installutil.exe")
Dim InstallUtilProcess As Process = Process.Start(InstallUtilPath, """" & ServicePath & """")
InstallUtilProcess.WaitForExit()
'Service is now installed.
InstallUtilProcess = Process.Start(InstallUtilPath, "/i """ & ServicePath & """")
InstallUtilProcess.WaitForExit()
'The second action is now done. Show a MessageBox or something if you'd like.
End Sub
The ServicePath parameter is the path to the service that you want to install.
The InstallUtilPath variable will be set to the path of the installutil.exe application. It will get the path for the current framework you're running.
As I'm running .NET Framework 4 the path is C:\Windows\Microsoft.NET\Framework\v4.0.30319\installutil.exe
Hope this helps!
