'Objects in this class cannot be updated outside an edit session'

<P>                ipWorkEdit.StartEditing(false);<BR>                ipWorkEdit.StartEditOperation();<BR>                //根据OID重新查询Feature<BR>                IQueryFilter ipQuery = new QueryFilterClass();<BR>                ipQuery.WhereClause = "ObjectID=" + m_FeatureAdd.OID.ToString();<BR>                IFeatureCursor ipCursor = ipFeaCls.Update(ipQuery,false);<BR>                IFeature ipFeature = ipCursor.NextFeature();<BR>                if (ipFeature == null) return false;</P>
<P>                IFields ipFields = ipFeature.Fields;<BR>                int index=ipFields.FindField("PEID");<BR>                ipFeature.set_Value(index, info.PEID);<BR>                //ipFeature.Store();<BR>                ipCursor.UpdateFeature(ipFeature);<BR>                ipWorkEdit.StopEditOperation();<BR>                ipWorkEdit.StopEditing(true);<BR>为什么我一运行到IFeatureCursor ipCursor = ipFeaCls.Update(ipQuery,false);就抛出异常  'Objects in this class cannot be updated outside an edit session'  </P>

高手请帮帮忙

<P>IFeatureCursor ipCursor = ipFeaCls.Update(ipQuery,false);<BR>你为什么这么得到ipCursor ,</P>
<P>些错了吧 ，应该是</P>
<P>IFeatureCursor ipCursor = ipFeaCls.serch(ipQuery,false);<BR></P>
