1. 一个有益的实验。
在Microsoft SQL Server Management Studio中建立一数据库查询。SQL语句如下：
select * from sys.databases
你会看到你需要的信息。现在估计该问题你已经知道怎么解决了，当然其中的道理估计你也明白，这里就不详述。
2. 一个实例。代码如下：
public string ConnectionString
...{
get
...{
return "server = " + m_ServerName + "; uid = sa; pwd = sa";
}
}
private void LoadCatalog()
...{
this.cbCatalog.Items.Clear();
if (Server.Equals(""))
...{
MessageBox.Show("Please input server address");
return;
}
string cmdStirng = "select name from sys.databases where database_id > 4";
SqlConnection connect = new SqlConnection(ConnectionString);
SqlCommand cmd = new SqlCommand(cmdStirng, connect);
try
...{
connect.Open();
IDataReader dr = cmd.ExecuteReader();
cbCatalog.Items.Clear();
while (dr.Read())
...{
cbCatalog.Items.Add(dr["name"]);
}
dr.Close();
}
catch (SqlException except)
...{
MessageBox.Show(this, except.Message);
}
finally
...{
if (connect != null && connect.State == ConnectionState.Open)
connect.Dispose();
}
}

C# 如何获取已知SQL server 2000服务器上数据库列表
已经知道SQL Server 2000 服务器，那想获取该服务器上的所有数据库并把它们在ComboBox显示出来要如何实现！！谢谢各位大师喽````呵呵`````
---------回复--------------
select * from master..sysdatabases
---------回复--------------
use master
go
select name from sysdatabases
---------回复--------------
居然是同一秒...

应该是获取局域网中的所有 SQL Server 服务器然后选定一个服务器并获取该服务器上的所有数据库并把它们在ComboBox显示出来要如何实现！！谢谢各位大师喽````呵呵`````

SQLDMO.dll文件好像没有``所以无法运行`````````
