Question

数据库连接问题 127.0.0.1和localhost有什么区别？

在我得.net2003里，字符串是localhost就联不上SQLSERVER，而127.0.0.1或者"."就可以连上，为什么？这么解决？
我得host 文件内容是：127.0.0.1 localhost
没有问题!

日，现在又没问题啦，哪种都可以连上。
就没人能解释以下吗？？？？？？？？？？？？？？？

此问题无满意答案，没有人能解释得清楚。。。。。。。
但要多谢各位得回答，分数就不浪费啦。。。。。。。。

Answer 1

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

[C:\WINDOWS\system32\drivers\etc]

Answer 2

应该都可以联上的,它两之间不同在于,把网线断开后,127.0.0.1就不好用了而
localhost就可以.
