ArcEngine中拷貝feature時候報錯

  public static void MyInsertFeature(IFeatureClass pFeatureClass, IGeometry pGeometry)
    {
        IFeatureBuffer pFeatureBuffer=null;
        int typeFieldIndex = pFeatureClass.FindField("Layer");
        pFeatureBuffer = pFeatureClass.CreateFeatureBuffer();
        IFeatureCursor insertCursor = pFeatureClass.Insert(true);
        pFeatureBuffer.set_Value(typeFieldIndex, "ZBTZ");       
        pFeatureBuffer.Shape = pGeometry;
        insertCursor.InsertFeature(pFeatureBuffer);
    }

程序調試時，每次到 pFeatureBuffer.Shape = pGeometry;這裡就報錯“這個集合中找不到此項目。”，pGeometry明明不是null啊.求高手解答啊。困擾好久了。很郁悶。

最佳回答：

找到原因了！！！原來是數據類型不匹配，所以不能賦值。
在featureclass定義的時候應該加上geometryDefEdit.HasZ_2 = true;
不然無法將3d數據強行賦給2d的
