the standard method requires to run arcpy script in commande line, i've struggled with it to run but without a result, i can import arcpy, set the workspace to the geodatabase path and describe the env variable using arcpy.Describe(arcpy.env.workspace).name it gimme the geodatabase name, but when i try to get featureclasses using arcpy.ListFeatureClasses() i get [], i have made sure that all the environement variables in PATH and PYTHONPATH are ok .

i would like to know if there's an alternative way to run arcpy script, like it could be run in Arcmap console, is there a way to send scripts to arcmap console using Arcobjects, what's the difference between Arcmap console and standard commande line console ?

so any way to run an Arcpy script using Arcobjects 10 or Arcgis Engine 10 will be very welcome.

I suggest you get the Python script working by itself first before trying to call it from another environment. – blah238 Jun 26 '12 at 3:10
i've tested Arcpy script in Arcmap console, it works like expected in arcmap, but in commande line console, it do not work – geogeek Jun 26 '12 at 7:37

There may be several options. If you package your script into a toolbox you could reference your toolbox (and tool) via ArcObjects as such:

 IGeoProcessor2 gp = new GeoProcessorClass();
 gp.AddToolbox(@"C:\YourPath\YourToolbox.tbx");
 parameters.Add(@"C:\YourPath\ParamsIfYouHaveThem.gdb\ParamFC");
 gp.Execute("NameOfYourToolInsideReferencedToolbox", parameters, null);

Read more on this method here: http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#executingCustomTool

Or you could try this route:

System.Diagnostics.Process proc = new System.Diagnostics.Process();
proc.StartInfo.FileName = @"C:\path\toYour\script.py";
proc.StartInfo.UseShellExecute = true;
proc.Start()

which is mentioned here: http://forums.esri.com/Thread.asp?c=93&f=993&t=276632

thanks for your quick answer, i've tested the second solution, it uses system shell so the problem persists, i had'nt worked, concerning the first choice i need some time to create a toolbox and test it again. – geogeek Jun 25 '12 at 23:52
I've personally used the former with success, so I can vouch for that. The latter is one I haven't tried so I can't speak to it efficacy firsthand. Let me know if you have any question about the former method. – AHigh Jun 26 '12 at 2:18
it WORKS LIKE A CHARM, thanks a lot. i hope i could run all arcpy scripts by this way. – geogeek Jun 26 '12 at 7:37

I think you need to execute arcpy.ListFeatureClasses to get a list of featureclasses in your geodatabase.

This is correct, ListDatasets lists Feature Datasets but not Feature Classes. The terminology is unfortunate of course, but a feature dataset is a container for feature classes -- ESRI doesn't use consistent terminology when they use the term dataset. Sometimes it means a container, sometimes it means an individual table/feature class. – blah238 Jun 26 '12 at 3:12
thanks i've made an edit, but in despite of using arcpy.ListFeatureClasses() i get an empty array, but in ArcMap console i get all the featureclasses [u'new_dir_sj', u'new_dir6', u'dir_buf', u'div_riv'] – geogeek Jun 26 '12 at 6:06
