How to get SQL Server 2000 instance list and run a database list on an instance

server|sqlserver| Data | database

In the. Net framework, it is easy to invoke COM components, and sometimes we need to get a list of service instances running on a SQL Server and a database listing on an instance. This work can be done easily with the Microsoft.SQLDMO.Object component:
First how to find Microsoft.SQLDMO.Object
1. How can I use the SQLDMO component in your project?
Menu-item-Add Reference-com-microsoft.sqldmo.object

2. Write the function as a class:

1using System;
2using System.Collections;
3using System.Collections.Specialized;
