I have been using this simple C# code to copy featureclasses between geodatabases (ArcObjects SDK 10.0):
CopyFeatures cf = new CopyFeatures;
cf.in_features = "C:\\geodb1.mdb\\MyFeatureClass";
cf.out_feature_class = "C:\\geodb2.gdb\\MyFeatureClass";
Geoprocessor gp = new Geoprocessor();
gp.OverwriteOutput = true;
gp.AddOutputsToMap = false;
After installing ArcObjects 10.3, "Geoprocessor.Execute()" is using other parameters, but somehow I cannot find any code examples or documentation dealing with this situation.
Any suggestions ?
