I am trying to create a console application that will do several things like stop a service.  One of the tasks it must do is drop a database.  The code I have come up with is:

string sqlcmd = "sqlcmd –d master –Q drop database test";
                ProcessStartInfo ProcessProperties = new ProcessStartInfo();
                ProcessProperties.FileName = "cmd.exe";
                ProcessProperties.Arguments = sqlcmd;
                ProcessProperties.UseShellExecute = false;
                Process myprocess = Process.Start(ProcessProperties);

When I run the sqlcmd from the commandline then it deletes the database.  



What I am after is passing this to the commandline from my application

sqlcmd -d master -Q "drop database test"  

Can someone please help me with that.  

Thanks.

There are different ways to stop a service:

1) SC command from a command line
2) ServiceProcess/Controller

I don't see the need for using cmd.exe here. Calling sqlcmd should be enough. You might have to provide the path to it, if PATH isn't set accordingly.
string sqlcmd = "–d master –Q drop database test";
                ProcessStartInfo ProcessProperties = new ProcessStartInfo();
                ProcessProperties.FileName = "sqlcmd.exe";
                ProcessProperties.Arguments = sqlcmd;
                ProcessProperties.UseShellExecute = false;
                Process myprocess = Process.Start(ProcessProperties);

What is the console application written in? Why not use the direct connection to the server. Then use the alter databse state to single user mode which will disconnect all other sessions which is presumably why you are looking to stop the service.

Other experts may provide an alternative approach if you could provide additional details on what the purpose of what you want to do from A to Z.
