WebPermissionAttribute.Accept Property

Gets or sets the URI string accepted by the current WebPermissionAttribute.

[Visual Basic]
Public Property Accept As String
[C#]
public string Accept {get; set;}
[C++]
public: __property String* get_Accept();
public: __property void set_Accept(String*);
[JScript]
public function get Accept() : String;
public function set Accept(String);

Property Value

A string containing the URI accepted by the current WebPermissionAttribute.

Exceptions

Exception Type Condition
ArgumentException Accept is not a null reference (Nothing in Visual Basic) when you attempt to set the value. If you wish to specify more than one Accept URI, use an additional attribute declaration statement.

Remarks

When applying WebPermissionAttribute to your class, this property specifies what URI string will be accepted for use within your class. This permission is applied when the security system calls CreatePermission. This property is write-once.

Example

[Visual Basic, C#, C++] The following example demonstrates how to use WebPermissionAttribute to specify an allowable Accept string.

[Visual Basic] 

    ' Deny access to a specific resource by setting the Accept property.

   <WebPermission(SecurityAction.Deny, Accept := "http://www.contoso.com/Private.htm")>  _
      Public Shared Sub CheckAcceptPermission(uriToCheck As String)
      Dim permissionToCheck As New WebPermission()
      permissionToCheck.AddPermission(NetworkAccess.Accept, uriToCheck)
      permissionToCheck.Demand()
   End Sub 'CheckAcceptPermission
   
   
   Public Shared Sub demoDenySite()
      ' Pass the security check when accessing allowed resources.
      CheckAcceptPermission("http://www.contoso.com/Public.htm")
      Console.WriteLine("Public page has passed Accept permission check")
      Try
         'Throw a SecurityException when trying to access not allowed resources.
         CheckAcceptPermission("http://www.contoso.com/Private.htm")
         Console.WriteLine("This line will not be printed")
      Catch e As SecurityException
         Console.WriteLine(("Exception trying to access private resource:" + e.Message))
      End Try
   End Sub 'demoDenySite

[C#] 


  
// Deny access to a specific resource by setting the Accept property.
[WebPermission(SecurityAction.Deny, Accept=@"http://www.contoso.com/Private.htm")]

public static void CheckAcceptPermission(string uriToCheck) 
{
    WebPermission permissionToCheck = new WebPermission();
    permissionToCheck.AddPermission(NetworkAccess.Accept, uriToCheck);
    permissionToCheck.Demand();
}

public static void demoDenySite() 
{
    //Pass the security check when accessing allowed resources.
    CheckAcceptPermission("http://www.contoso.com/");
    Console.WriteLine("Public page has passed Accept permission check");

    try 
    {
        //Throw a SecurityException when trying to access not allowed resources.
        CheckAcceptPermission("http://www.contoso.com/Private.htm");
        Console.WriteLine("This line will not be printed");
    }
    catch (SecurityException e) 
    {
        Console.WriteLine("Exception trying to access private resource:" + e.Message);
    }

 }


[C++] 
// Deny access to a specific resource by setting the Accept property.
[method:WebPermission(SecurityAction::Deny, Accept="http://www.contoso.com/Private.htm")]
static void CheckAcceptPermission(String* uriToCheck) {
   WebPermission* permissionToCheck = new WebPermission();
   permissionToCheck->AddPermission(NetworkAccess::Accept, uriToCheck);
   permissionToCheck->Demand();
}

public:
static void demoDenySite() {
   // Pass the security check when accessing allowed resources.
   CheckAcceptPermission(S"http://www.contoso.com/");
   Console::WriteLine(S"Public page has passed Accept permission check");

   try {
      // Throw a SecurityException when trying to access not allowed resources.
      CheckAcceptPermission(S"http://www.contoso.com/Private.htm");
      Console::WriteLine(S"This line will not be printed");
   } catch (SecurityException* e) {
      Console::WriteLine(S"Exception trying to access private resource: {0}", 
         e->Message);
   }
}
