Connect to ArcSDE

Refer to ".NET Help for VS2005" ,I get the code as follows:

        public IWorkspace OpenArcSDEWorkspace(string server, string instance, string user,
        string password, string database, string version)
        ...{
            ESRI.ArcGIS.esriSystem.IPropertySet propertySet = new ESRI.ArcGIS.esriSystem.PropertySetClass();
            propertySet.SetProperty("SERVER", server);
            propertySet.SetProperty("INSTANCE", instance);
            propertySet.SetProperty("DATABASE", database);
            propertySet.SetProperty("USER", user);
            propertySet.SetProperty("PASSWORD", password);
            propertySet.SetProperty("VERSION", version);

            IWorkspaceFactory workspaceFactory = new ESRI.ArcGIS.DataSourcesGDB.SdeWorkspaceFactoryClass();
            return workspaceFactory.Open(propertySet, 0);
        }

 

also you can use the  ArcCatalog to test the connection,and i will use the ArcCatalog 9.2 as an example to illustrate.

first ,start up the ArcCatalog 9.2 as image 1 shows.

Double click the "Add Spatial Database Connection" then a dialog display on current page,configure the parameter as image 2 shows:
