[ACCEPTED]-How do I return a value from a console application to a service in .NET?-console-application
Process p = Process.Start("app.exe");
p.WaitForExit();
int number = p.ExitCode;
And in app.exe you set Enviroment.ExitCode...
0
you can make use of an Exit Code by changing 2 your Main method from
public void Main(string[] args){return;}
to
public int Main(string[] args){return 0;}
Not an elegant solution, but 1 it works.
An arbitrary number can be returned via 3 standard ExitCode mechanism. You'd just have to 2 Start() a process, then WaitForExit(), and then get the value 1 of ExitCode.
You can use the exit code, which can be 11 returned from the Main function or set via 10 Environment.ExitCode.
Another option would 9 be to have your ConsoleApp write to the 8 standard output stream, and redirect the 7 output to your main application.
The advantage 6 of the second option is that you could return 5 more data than a single integer, if later 4 you find this necessary. The disadvantage 3 is that it's a bit more work to setup.
This 2 CodeProject article walks through redirecting the standard 1 output streams of a spawned process.
The console app can set its exit code.
The 3 console app can set its exit code by either:
- Call
System.Environment.Exit(exitcode), or - Let the
mainfunction return an int.
The 2 ExitCode property (of the System.Diagnostics.Process class) lets the service 1 process examine the console app's exit code.
