Capture python print statements in C# -

i writing c# component takes ironpython function parameter.

    def test():         x=x+1         print "test" 

c#:

    var v = engine.operations.invoke(scope.getvariable("test")); 

var v returns null print statements. works if have return(x). can capture print statements using ironpython?

comments , links appreciated. also, can capture using commandline?

this works me:

var script = @"import sys def test():      print sys.version     print >> sys.stderr, 'this goes stderr'     return 42";  var scriptengine = python.createengine(); var scriptscope = scriptengine.createscope(); scriptengine.execute(script, scriptscope); var testfn = scriptscope.getvariable("test"); var streamout = new memorystream(); var streamerr = new memorystream(); scriptengine.runtime.io.setoutput(streamout, encoding.default); scriptengine.runtime.io.seterroroutput(streamerr, encoding.default); scriptengine.operations.invoke(testfn); console.writeline("returned: {0}", scriptengine.operations.invoke(testfn)); console.writeline("captured out:\n{0}", encoding.default.getstring(streamout.toarray())); console.writeline("captured err:\n{0}", encoding.default.getstring(streamerr.toarray())); 

output:

returned: 42 captured out: 2.7.5b2 (ironpython 2.7.5b2 (2.7.5.0) on .net 2.0.50727.5477 (64-bit))  captured err: goes stderr
