我的Web.config
文件突然出现以下错误,我不明白这意味着什么:
解析器错误消息:属性“connectionStringName”缺失或为空。
Line 24: <providers>
Line 25: <clear />
Line 26: <add name="SMDPortalMembershipProvider" type="SMDPortalMembershipProvider" />
Line 27: </providers>
Line 28: </membership>
源文件:c:\inetpub\wwwroot\web.config 行:26
版本信息:Microsoft .NET Framework 版本:4.0.30319;ASP.NET 版本:4.0.30319.272
这是我的配置文件:
