using System;using System.Collections.Generic;using System.Text;using System.Data.Odbc;using System.Data.OleDb;namespace ODBCtest{ class Program { static void Main(string[] args) { //ODBC連接 string conString = "DSN=tian"; //tian表示ODBC的用戶數(shù)據(jù)源名 string sql = "select count(*) from stuinfo"; //stuinfo為用戶數(shù)據(jù)源綁定的數(shù)據(jù)庫中的一個(gè)表 OdbcConnection con = new OdbcConnection(conString); con.Open(); OdbcCommand com = new OdbcCommand(sql, con); int i = Convert.ToInt32(com.ExecuteScalar()); Console.WriteLine(i); //OLEDB連接 string conString = @"Provider=Microsoft.Jet.OLEDB.4.0;Data Source=D:\tian.mdb"; //連接Access數(shù)據(jù)庫 string sql = "select count(*) from stuinfo"; OleDbConnection con = new OleDbConnection(conString); con.Open(); OleDbCommand com = new OleDbCommand(sql, con); int i = Convert.ToInt32(com.ExecuteScalar()); Console.WriteLine(i); } }} |
希望本文所述對(duì)大家C#程序設(shè)計(jì)有所幫助。
