怎样打开通过CreateEnterpriseGeodatabase工具创建的空间库呢？

可参考下面代码：
IPropertySet propertySet = new PropertySetClass();
 //直连SQL Server数据库
propertySet.SetProperty("SERVER", "192.168.220.134");
propertySet.SetProperty("INSTANCE", "sde:sqlserver:192.168.220.134");
propertySet.SetProperty("USER", "sde");
propertySet.SetProperty("PASSWORD", "sde");
propertySet.SetProperty("DATABASE", "sde103");      
IWorkspaceFactory sdewf = new SdeWorkspaceFactoryClass();
IWorkspace targetWorkspace = sdewf.Open(propertySet, 0);
