怎么看路径？

[fei缘如水]

404 找不到页面。你看看路径

[全栈极简]

404是路径不对，检查一下路径吧。

web.config 文件代码如下： <?xml version="1.0"?> <!-- 办公室： <add name="DTDC" connectionString="Data Source=TDJ-PC\WAKING;Initial Catalog=DegreeThesisDatabase;Integrated Security=True" providerName="System.Data.SqlClient"/> 家里面： <add name="DTDC" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=G:\工程\thesis\App_Data\DegreeThesisDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True" providerName="System.Data.SqlClient"/> 有关如何配置 ASP.NET 应用程序的详细信息，请访问 http://go.microsoft.com/fwlink/?LinkId=169433 --> <configuration> <connectionStrings> <add name="DTDC" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=E:\毕业设计\thesis原版\App_Data\DegreeThesisDatabase.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True" providerName="System.Data.SqlClient"/> </connectionStrings> <system.web> <authentication mode="Forms" > <forms name="casauth" loginUrl="caslogin.aspx" /> </authentication> <authorization> <deny users="?" /> </authorization> <httpRuntime executionTimeout="36000" maxRequestLength="2097151"/> <compilation debug="true" strict="false" explicit="true" targetFramework="4.0"> <assemblies> <add assembly="Office, Version=11.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"/> <add assembly="Microsoft.Office.Interop.Word, Version=11.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c"/> </assemblies> </compilation> <membership> <providers> <clear/> <add name="AspNetSqlMembershipProvider" type="System.Web.Security.SqlMembershipProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="/"/> </providers> </membership> <profile> <providers> <clear/> <add name="AspNetSqlProfileProvider" type="System.Web.Profile.SqlProfileProvider" connectionStringName="ApplicationServices" applicationName="/"/> </providers> </profile> <roleManager enabled="false"> <providers> <clear/> <add name="AspNetSqlRoleProvider" type="System.Web.Security.SqlRoleProvider" connectionStringName="ApplicationServices" applicationName="/"/> <add name="AspNetWindowsTokenRoleProvider" type="System.Web.Security.WindowsTokenRoleProvider" applicationName="/"/> </providers> </roleManager> </system.web> <system.webServer> <modules runAllManagedModulesForAllRequests="true"/> </system.webServer> </configuration>

怎么看路径？

比如你要链接到X文件夹下的A页面。那路径就是 X\A.aspx这样的地址，你要显示的页面的路径在哪

[mr_mrl]

我要打开的是E:\毕业设计\thesis原版\caslogin文件

[fei缘如水]

你那文件有在项目里没。。另外是文档还是页面？

[mr_mrl]

在呀，我这个是网页文件，里面都是各种网页和代码，大神，要不我加你QQ吧，求大恨帮我把这个问题解决了。

路径不知道写，就把右侧文件夹里的需要打开的页面直接拖到页面上会有个路径 你再贴到转页的地方。。。我也是上班ing，有点空就回复下你，一会说不定就没空了

[mr_mrl]

恩恩，谢谢大神了，我觉得是我的web.config文件配置的问题，现在网页文件里面的网页都打不开了，都是提示此错误。

[wdh123love]

根目录下找不到"caslogin"文件夹，看一下你是不是以/caslogin为根目录了

[mr_mrl]

我的网页文件的根目录是thesis原版，其下面也没有caslogin这个文件夹。
