ArcSDE的连接代码(C#)

本机作为服务器时：

            //加载sde中管理的数据
            IPropertySet propertySet = new PropertySetClass();
            propertySet = new PropertySetClass();
            propertySet.SetProperty("server", "letter");//服务器名(电脑名)。连接远程服务器的时候改成IP如192.168.1.102
            propertySet.SetProperty("instance", "sde:oracle11g:orcl");//orcl是数据库实例名（全局名）
            propertySet.SetProperty("user", "sys");//sde用户名
            propertySet.SetProperty("password", "123456");//密码
            propertySet.SetProperty("version", "SDE.DEFAULT");//版本
            //propertySet.SetProperty("AUTHENTICATION_MODE", "DBMS");
            //propertySet.SetProperty("database", "orcl");//当不只一个数据库时进行设定
            IWorkspaceFactory workspaceFactory = new SdeWorkspaceFactory();
            IWorkspace workspace = workspaceFactory.Open(propertySet, 0);
