代碼如下：
IFeatureLayer pFeatureLayer = chuanzhi.j;
IQueryFilter pFilter = new QueryFilterClass();
pFilter.WhereClause = "小區名稱='"+textBox1.Text+"'";
IFeatureCursor pFeatureCursor;
pFeatureCursor = pFeatureLayer.Search(pFilter, true);
IFeature pFeat;
pFeat = pFeatureCursor.NextFeature();
IGeometry pGeometry;
ITopologicalOperator pTop;
pTop = pFeat as ITopologicalOperator;
pGeometry = pTop.Buffer(1000);//在此行提示未將物件參考設定到物件的實體
P.S. pFeatureLayer為從chuanzhi類賦值的圖層
