I have an xml file and i want to use it in my ASP.Net (C#) application. Everything is working fine but when i run application i get the following erros.Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.UnauthorizedAccessException: Access to the path "F:\My downloads\7582_BegVCSharpEnd\BegVCSharpEnd\Chapter23\Weblog\Entries\20010717_1607.xml" is denied. 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. If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user. To grant ASP.NET write 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.The solution above suggested is some thing that i didn't understand and i tried more than 10 times to follow the solution above suggeste but i couldn't do so.
