C# soe 获取 本服务的FeatureClass

搭建好的soe 环境中，通过IMapServer3直接获取featureclass

int index = 0; //0,1,2,...
IMapServer3 mapServer = (IMapServer3)serverObjectHelper.ServerObject;
IMapServerDataAccess dataAccess = (IMapServerDataAccess)mapServer;
var FeatureClass = (IFeatureClass)dataAccess.GetDataSource(mapServer.DefaultMapName, index)；
