C语言操作ADO数据库 这些操作是对一个微软Access 2000数据库进行的,但是SQL或是其它 ADO数据源可以通过简单的改变连接字符串来使用.

using System.Data;
using System.Data.OleDb;
---------------------------
OleDbConnection thisConnection=new OleDbConnection(@"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\D\DevCs\Works2\Person.mdb;");
thisConnection.Open();
OleDbCommand thisCommand=thisConnection.CreateCommand(); //
thisCommand.CommandText="SELECT * FROM Intro";
OleDbDataReader thisReader=thisCommand.ExecuteReader();
while(thisReader.Read())
	{
	Console.WriteLine("\t{0}\t{1}",thisReader["ID"],thisReader["TheName"]);
	}
thisReader.Close();
thisConnection.Close();
