ArcGIS Engine 如何连接用户的Schema？

IPropertySet propertySet = new PropertySetClass(); 



//直连Orcale 用户的user schema 

propertySet.SetProperty(SERVER, ); 

propertySet.SetProperty(INSTANCE, sde:oracle11g:192.168.220.131/orcl:uuu); 

propertySet.SetProperty(DATABASE, ); 

propertySet.SetProperty(USER, uuu); 

propertySet.SetProperty(PASSWORD, 123); 

propertySet.SetProperty(VERSION, uuu.DEFAULT); 





IWorkspaceFactory sdewf = new SdeWorkspaceFactoryClass(); 

IWorkspace targetWorkspace = sdewf.Open(propertySet, 0);
