新建.shp类型的FeatureClass，一系列操作后，想要删除源文件。如何解除文件的占用？

这个问题我以前遇到过，后面仔细看了shapefile白皮书，发现shapefile文件有应该有四种lock文件
SR - schema lock
RD - read lock
ED - edit lock
WR-write lcok
第一种是常规的lock文件，使用arcmap加载的时候也会自动生成这种lock文件，所以这种文件
解锁是比较容易，直接使用IWorkspaceFactoryLockControl 接口即可

    IWorkspaceFactory2 ipWsFactory = new FileGDBWorkspaceFactoryClass();  

    IWorkspaceFactoryLockControl ipWsFactoryLock;     

    ipWsFactoryLock = (IWorkspaceFactoryLockControl)ipWsFactory;  

                  

    if (ipWsFactoryLock.SchemaLockingEnabled)  

    {  

        ipWsFactoryLock.DisableSchemaLocking();  

    } 

第二种是读取文件的时候自动生成的lock文件，暂时没有遇到过这种锁文件
第三种很明显就是编辑时候自动生成的lock文件，停止编辑会自动消失
第四种，也就是你这里遇到的，在create shp文件的时候生成的，释放游标的方法我没有试过，但你这里
没用。我当时的解决方案是，既然不用生成这个文件，为何不直接CreateFeatureBuffer

            try

            {

                featureClass = (inmemWor as IFeatureWorkspace).CreateFeatureClass(featureClassName + ".shp", fields, CLSID, CLSEXT, esriFeatureType.esriFTSimple, "shape", strConfigKeyword);

            }

            catch (Exception ex)

            {

                throw new Exception("创建内存图层失败"+ex);

            }

            finally

            {

                try

                {

                    Marshal.ReleaseComObject(fields);

                    Marshal.ReleaseComObject(fieldsEdit);

                    Marshal.ReleaseComObject(name);

                    Marshal.ReleaseComObject(workspaceFactory);

                    Marshal.ReleaseComObject(workspaceName);

                    Marshal.ReleaseComObject(inmemWor);

                    //System.Runtime.InteropServices.Marshal.ReleaseComObject(oFeatureClass);

                }

                catch

                {

                }



                GC.Collect();

            }

            if (featureClass == null)

            {

                throw new Exception("创建内存图层失败");

            }

            IFeatureCursor featureCursorInsert = featureClass.Insert(true);

            IFeatureBuffer featureBuffer = featureClass.CreateFeatureBuffer();

            var pFeature = featureBuffer as IFeature;

            pFeature.Shape = pGeometry;

 

删除使用IDataset.Delete();IFeatureClass也要释放

具体是图片上这样，还有哪儿没有释放呢？

ESRI.ArcGIS.ADF.RealeaseCOMObject(shapefileWorkspaceFactory);
ESRI.ArcGIS.ADF.RealeaseCOMObject(workspace);
ESRI.ArcGIS.ADF.RealeaseCOMObject(featureClass);
ESRI.ArcGIS.ADF.RealeaseCOMObject(featureCursor);
用到的COM对象都要释放，还有IField，IFields，IFeature，IFeatureBuffer
