没有授权ASP.NET访问请求的资源.考虑将资源的访问权限授予ASP.NET请求标识. ASP.NET具有一个基本进程标识(在IIS 5上通常为{MACHINE} \ ASPNET或在IIS 6上通常为Network Service)，如果应用程序无法模拟，则使用该标识.

要授予ASP.NET对文件的访问权限，请在资源管理器中右键单击该文件，选择属性"，然后选择安全性"选项卡.单击添加"以添加适当的用户或组.突出显示ASP.NET帐户，然后选中所需访问权限的框.

ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6) that is used if the application is not impersonating.

To grant ASP.NET access to a file, right-click the file in Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
