上述代码有什么问题吗？

是不是Console.WriteLine("\t{0}\t{1}",thisReader["姓名"]); 这句话的t{1}没赋值啊

贴一下你的输出呗

SqlConnection thisConnection = new SqlConnection(@"Server=(local)\sqlexpress;Integrated Security=True;" + "Database=master");

 打开数据库要这样写吗  

我感觉是

SqlConnection thisConnection = new SqlConnection("Server=(local)\sqlexpress;Integrated Security=True;Database=master");  

最好加上try，catch结构
有什么问题都能处理

楼主程序代码如下问题：
一.本地SQLSERVER服务器，连接字符串输写：
SqlConnection thisConnection = new SqlConnection(@"Server=(local);Integrated Security=True;" + "Database=master");
二、控制台输出：
Console.WriteLine("\t{0}\t",thisReader["姓名"]);

同意四楼和五楼，
另外楼主应该把报错信息说一下啊，大家好有针对性的解答~~

同意六楼

同意7楼，加上try（）catch（）最好，规范点！调试的时候遇到什么问题也跟大家说一下啊，这样有
针对性！

把
SqlConnection thisConnection = new SqlConnection(@"Server=(local)\sqlexpress;Integrated Security=True;" + "Database=master");
改为
SqlConnection thisConnection = new SqlConnection(@"Server=(local)\\sqlexpress;Integrated Security=True;" + "Database=master");

把
Console.WriteLine("\t{0}\t{1}",thisReader["姓名"]);
改为
Console.WriteLine("\t{0}",thisReader["姓名"]);
