AE+C#批量修改MXD中图层数据源

AE+C#批量修改MXD中图层数据源

 

在实际的工作中经常遇到MXD找不到数据源或者没有需要批量转换数据源，本文样例代码为AE+C#如何批量修改MXD的数据源。

 

代码如下

                stringpath = @"D:\temp";

                stringsdeName = @"localhost.sde";

                stringsdePath = path +"\\" + sdeName;

                if(File.Exists(sdePath))

                {

                    File.Delete(sdePath);

                }

                IWorkspaceFactorypWorkspaceFactory =new SdeWorkspaceFactoryClass();

                IWorkspaceNamepWorkspaceName = pWorkspaceFactory.Create(path, sdeName, ConnectSDE(true), 0);

 

                ILayerpLayer =null;

                IFeatureLayerpFeatureLayer =null;

                IDataLayer2pDataLayer =null;

                IDatasetNamepDatasetName =null;

 

                for(int i = 0; i < mapCtrl.LayerCount; i++)

                {

                    //获取图层

                    pLayer = null;

                    pLayer =mapCtrl.get_Layer(i);

                    pFeatureLayer = (IFeatureLayer)pLayer;

                    stringlayername = pLayer.Name;

                    if(pLayer is IDataLayer)

                    {

                        pDataLayer = (IDataLayer2)pFeatureLayer;

                        pDatasetName = (IDatasetName)pDataLayer.DataSourceName;

                        try

                        {

                            if (pFeatureLayer.FeatureClass !=null)

                            {

                                if (!(pFeatureLayerisIDimensionLayer))

                                {

                                   pDataLayer.Disconnect();

                                }

                            }

                           pDatasetName.WorkspaceName = pWorkspaceName;

 

                           pDataLayer.Connect((IName)pDatasetName);

                        }

                        catch (Exception ex)

                        {

                            string msg = ex.Message;

                        }

                    }

                }

                mapCtrl.Refresh();

  

主要用的接口是IDataLayer2。其中对于IDimensionLayer类型的数据，pDataLayer.Disconnect();

没有实现，这里已经进行了屏蔽。
