2 {
3 IPropertySet propertySet = new PropertySetClass();
4 propertySet.SetProperty("SERVER", "127.0.0.1");
5 propertySet.SetProperty("INSTANCE", "sde:sqlserver:127.0.0.1");
6 propertySet.SetProperty("DATABASE", "sde");
7 propertySet.SetProperty("USER", "sa");
8 propertySet.SetProperty("PASSWORD", "sa");
9 propertySet.SetProperty("VERSION", "SDE.DEFAULT");
10 Type factoryType = Type.GetTypeFromProgID("esriDataSourcesGDB.SdeWorkspaceFactory");
11 IWorkspaceFactory workspaceFactory = (IWorkspaceFactory)Activator.CreateInstance(factoryType);
12 return workspaceFactory.Open(propertySet, 0);
13 }
