原来这个选项卡是要经过一翻设置才能使用的(我用sqlserver2k5 enterprise edition, express edition我就不知道了)。首先,运行 aspnet_regsql 来安装membership所要建立的数据库。然后,修改机器上web.config文件(C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\CONFIG\web.config)或者是工程的web.config文件。我的工程下的web.config文件如下:
<?xml version="1.0" encoding="utf-8"?>
<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<connectionStrings>
<remove name="LocalSqlServer" />
<add name="LocalSqlServer" connectionString="Data Source=localhost;Initial Catalog=aspnetdb;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
要注意<connectionStrings> ... </connectionStrings>这个节<configuration xmlns="http://schemas.microsoft.com/.NetConfiguration/v2.0">
<connectionStrings>
<remove name="LocalSqlServer" />
<add name="LocalSqlServer" connectionString="Data Source=localhost;Initial Catalog=aspnetdb;Integrated Security=True"
providerName="System.Data.SqlClient" />
</connectionStrings>
<system.web>
<compilation debug="true"/>
</system.web>
</configuration>
如果你也遇到同样的问题,希望我篇文章能给你一点提示。
