C#2005与SQL2000相互连接?谁会啊

和2003的连接方法一样

怎么连接？你是指用程序连接数据库？
using System.Data.SqlClient;

SqlConnection cn = new SqlConnection("database=test;server=.;uid=sa;pwd=sa");
cn.Open();
.
.
cn.Close();

参考
private void ConnectToSQL2000()
{
string connstr = "Provider=SQLOLEDB.1;Password=csm;Persist Security Info=True;User ID=sa;Data Source=csm;";
System.Data.OleDb.OleDbConnection oleConn = new System.Data.OleDb.OleDbConnection(connstr);
System.Data.OleDb.OleDbCommand oleCmd=oleConn.CreateCommand();
oleCmd.CommandText = "select * from testTable";

System.Data.OleDb.OleDbDataReader oleRder=oleCmd.ExecuteReader();
while (oleRder.Read())
{
string testColumn=oleRder.GetString(oleRder.GetOrdinal("testColumn"));
//...
}
}
