Engine中执行gp工具返回的要素图层如何获取？

// Intialize the geoprocessor.

Geoprocessor GP = new Geoprocessor();



// Intialize the MakeFeatureLayer tool.

MakeFeatureLayer makefeaturelayer = new MakeFeatureLayer();



// Set up the GP tool parameters and run the tool.

makefeaturelayer.in_features = @C:\gp\nfld.gdb\wells;

makefeaturelayer.out_layer = Wells_Lyr;

makefeaturelayer.where_clause = WELL_YIELD > 150;



IGeoProcessorResult result = (IGeoProcessorResult)GP.Execute(makefeaturelayer, null);



IFeatureClass fc;

IQueryFilter qf;



IGPUtilities gpUtils = new GPUtilitiesClass();

gpUtils.DecodeFeatureLayer(result.GetOutput(0), out fc, out qf);



IFeatureCursor cursor = fc.Insert(true);
