数据库的配置: 连接字符串:server=潘尚\\SQLEXPRESS;database=db_test;Trusted_Connection=true 连接代码: using System;using System.Collections.Generic;using System.Data.SqlClient;using System.Linq;using System.Text;using System.Threading.Tasks;
using System; using System.Collections.Generic; using System.Data.SqlClient; using System.Linq; using System.Text; using System.Threading.Tasks; namespace SQLTest { class Program { static void Main(string[] args) { //连接数据库 string connection = "server=潘尚\\SQLEXPRESS;database=db_test;Trusted_Connection=true"; SqlConnection sc = new SqlConnection(); sc.ConnectionString = connection; try { sc.Open(); Console.WriteLine("已经打开数据库连接!"); } catch (Exception ex) { Console.WriteLine("打开数据库错误:{0}", ex.Message); } finally { sc.Close(); Console.WriteLine("数据库连接已关闭!"); } System.Console.ReadLine(); } } }
