大家帮我看看这个数据库连接哪错了呀

Question

SqlConnection   conn1   =   new   SqlConnection("server=192.168.1.141;uid=sa;pwd=123456"); 
在往里面加入一个database=:（缺少数据库）

Answer 1

server=192.168.1.141;uid=sa;pwd=123456
没有连接什么数据库应该还有一个database=xxx

Answer 2

 SqlConnection   conn1   =   new   SqlConnection("server=192.168.1.141;database=XX;uid=sa;pwd=123456"); 

Answer 3

      public   class   WebForm1   :   System.Web.UI.Page 
        { 
                private   void   Page_Load(object   sender,   System.EventArgs   e) 
                { 
                        Response.Write("第一个连接数据库的实例"); 
                        SqlConnection   conn1   =   new   SqlConnection("server=192.168.1.141;database=库名;uid=sa;pwd=123456"); 
                        try 
                        { 
                                conn1.Open(); 
                                Response.Write("链接成功！"); 
                        } 
                        catch 
                        { 
                                Response.Write("链接失败！"); 
                        } 
                }         } 

Answer 4

 SqlConnection   conn1   =   new   SqlConnection("server=192.168.1.141;uid=sa;pwd=123456");
