Analysis of ASP. NET Access Permissions

. Aspx page form code:

 
 

  
  
<form id="form1" runat="server"> 
  
  
<div> 
  
  
<asp:Button ID="Button1" runat="server" Text="Button" OnClick=
"Button1_Click" /><asp:FileUpload ID="FileUpload1" 
  
  
runat="server" /> 
  
  
</div> 
  
  
</form> 
 
 

Click Event code of Button1:

 
 

  
  
this.FileUpload1.SaveAs(Server.MapPath(".")); 
 
 

The following error occurs:

The server error in the "/linkupload" application.
Access to path "D: \ HL \ upload/Download \ linkupload" is denied.

Note: An unhandled exception occurs during the execution of the current Web request. Check the stack trace information for details about the error and the source of the error in the code.

Exception details: System. UnauthorizedAccessException: Access to path "D: \ HL \ upload/Download \ linkupload" is denied.

ASP. NET. Consider granting the ASP. NET Request identity the permission to access this resource. ASP. NET has a base process ID used when the application is not simulated (typically, {MACHINE} \ ASPNET on IIS 5 and Network Service on IIS 6 ). If the application is simulating through <identity impersonate = "true"/>, the identity will be an anonymous user (usually IUSR_MACHINENAME) or an authenticated user.

To grant ASP. NET access permissions to a file, right-click the file in resource manager, select "properties", and select the "Security" tab. Click Add to add an appropriate user or group. Highlight the ASP. NET account, and select the corresponding ASP. NET access permission box.

Source error:

The source code that generates this unprocessed exception is displayed only when compilation is performed in debug mode. To enable this feature, Perform one of the following steps and request the URL:

Add a "Debug = true" command at the top of the file that generated the error. For example:

 
 

  
  
<% @ PageLanguage="C #" Debug="True"%> 
  
  
Or:
  
  
2. Add the following section to the application configuration file:
  
  
<Configuration> 
  
  
<System. web> 
  
  
<Compilation Debug="True"/> 
  
  
</System. web> 
  
  
</Configuration> 
 
 

Note that the second step will compile all the files in the given application in debug mode. The first step will only compile the specific file in debug mode.

Important: running an application in debug mode will produce memory/performance system overhead. Before deploying a production solution, make sure that application debugging is disabled. The above describes ASP. NET access permissions.
