这里的(local)还可以是localhost或者127.0.0.1

从这里可以看出,应该写服务器的地址,由于是本地运行,而且在iis中绑定了127.0.0.1这个地址,所以写localhost和127.0.0.1都可以。另外,(local)是sql server 2000 中的服务器对象,所以也是可以的。如果在iis中将此网站设为默认网站,而且绑定地址169.254.218.201,则还可以这样连接:

private static string connstring = "server=169.254.218.201;database=webdevelop;uid=sa;pwd=sa";

如果是数据库教程在远程服务器上运行,则此处应该写远程服务器的ip地址。

另外,打开和读取数据库 中数据时,很容易抛出异常,所以不要经常捕捉,否则会出错

补充:asp.net教程,基础入门
