using BAT to setup windows service

First of all ,we must copy the ngen.exe and InstallUtil.exe to the windows service directory ,if we want to use the relative path

regist windows service Bat:            

                                                    InstallUtil    Test.exe  //the name of the service

                                                    net start "Test"       //start the service

unregist windows service Bat:          InstallUtil -u WindowsServiceFileupload.exe

(1)

    we double click the file,we can enter to the dos which could execute the command in the bat file

(2) 

     we use Process to start the bat file

there has a problem which the defualt directory is system32,so we must to point the abosulte path

%SystemRoot%\Microsoft.NET\Framework\v2.0.50727\InstallUtil.exe   "D:/Test.exe"

then the code :

            Process p = new Process();
            p.StartInfo.FileName =batFilePath;        

            p.Start();

            p.WaitForExit(30000);  join the thread

But what I want to say is it's no use in the develping like up ways!

what we want is using the relative ,so there give you a effective way

            Process p = new Process();
            p.StartInfo.FileName = batFilePath;

            p.StartInfo.WorkingDirectory = BasePath;        //point to the base diectory path    

            p.Start(); 

           p.WaitForExit(30000); 

the bat file we also can write as follow  which using the relative path

                                      InstallUtil    Test.exe  //the name of the service

                                      net start "Test"       //start the service
