Data Source=localhost/实例名 可以连接.但是用ip不行...因为我想局域网内都可以连接到我的数据库
你是不是TCP/IP协议那里没有启用啊
要启用了才能通过127.0.0.1此类的进行连接追问
要启用了才能通过127.0.0.1此类的进行连接追问
TCP/IP协议启用了
追答你用的是不是win7啊 或者你的host文件是不是有修改过关于local的指向
追问系统是win7的、这是hosts里面的
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost
win7里我也遇到过这个问题
最后我是用::1连接的
或者把# ::1 localhost里的#去掉也可以用localhost
还是操作数据库出错
追答数据库出错和连接就无关了吧，你安装的时候有问题还是什么。你自己能不能用企业管理器管理数据库啊
追问但是我用Data Source=.；就可以连接啊
追答你先确认下能不能在本机用企业管理器管理数据库。如果不行 要考虑安装的问题
其实能用什么方式连接就用什么方式没必要刻意要用localhost

你 hosts 文件没有定义
[C:\WINDOWS\system32\drivers\etc]type hosts
# Copyright (c) 1993-1999 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
127.0.0.1 localhost

改成和你一样后、还是不能通过127.0.0.1链接数据库

DNS没解析吧，用local
