ArcObject 要素更新

1 IFeature.Store() 更新要素属性

IFeatureCursor featureCursor = featureClass.Update(null, true);
IFeature feature = featureCursor .NextFeature();
while (feature != null)
{
    feature.set_Value(2, i);
    feature.Store();
    feature = featureCursor.NextFeature();
}

2 IFeatureCursor.UpdateFeature() 更新要素属性

IFeatureCursor featureCursor =featureClass.Update(null, true);
IFeature feature = featureCursor .NextFeature();
while (feature != null)
{
    feature.set_Value(2, i + 6);
    featureCursor.UpdateRow(feature);
    feature = featureCursor.NextFeature();
}

IFeatureCursor.UpdateFeature()的更新效率远远高于IFeature.Store()
