首先一定要獲取Featureclass，利用Featureclass獲取IWorkspace和IWorkspaceEdit：

??????????????? IWorkspace workspace = ((IDataset)pFeatureClass).Workspace;
??????????????? IWorkspaceEdit workspaceEdit = workspace as IWorkspaceEdit;

然后開啟編輯狀態：

??????????????? bool startEdit = workspaceEdit.IsBeingEdited();
??????????????? if (!startEdit)
??????????????? {
??????????????????? workspaceEdit.StartEditing(false);
??????????????? }
??????????????? workspaceEdit.StartEditOperation();

然后獲取IFeatureCursor和IFeature：

??????????????? pFeatureCursor = pFeatureClass.Search(pQueryFilter, false);

??????????????? //注意這里一定要為false，因為http://forums.arcgis.com/threads/45879-Cannot-call-Store-on-a-recycled-row-while-editing

??????????????? //如果為true可能會產生0x80040958的錯誤
????????????? ? pFeature = pFeatureCursor.NextFeature();

然后用IFeature.set_Value()方法對Feature進行屬性表值的修改：

???????????????? pFeature.set_Value(i, valueToSet);

修改完成，要用IFeature.store()方法保存：

????????????????pFeature.Store();

然后最好將Feature釋放掉，再進行接下來的修改：

??????????????? System.Runtime.InteropServices.Marshal.ReleaseComObject(pFeature);
??????????????? pFeature = null;
??????????????? pFeature = pFeatureCursor.NextFeature();

接下來用IFeatureCursor.Flush()：

??????????????? pFeatureCursor.Flush();
??????????????? System.Runtime.InteropServices.Marshal.ReleaseComObject(pFeatureCursor);

最后停止編輯狀態：
??????????????? workspaceEdit.StopEditOperation();
??????????????? startEdit = workspaceEdit.IsBeingEdited();
??????????????? if (!startEdit)
??????????????? {
??????????????????? workspaceEdit.StopEditing(true);
??????????????? }
