Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Gets or sets the URI string accepted by the current WebPermissionAttribute.
public:
property System::String ^ Accept { System::String ^ get(); void set(System::String ^ value); };
public string Accept { get; set; }
member this.Accept : string with get, set
Public Property Accept As String
A string containing the URI accepted by the current WebPermissionAttribute.
Accept is not null
when you attempt to set the value. If you wish to specify more than one Accept URI, use an additional attribute declaration statement.
The following example demonstrates how to use WebPermissionAttribute to specify an allowable Accept string.
public:
// 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 = gcnew WebPermission;
permissionToCheck->AddPermission( NetworkAccess::Accept, uriToCheck );
permissionToCheck->Demand();
}
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: {0}", e->Message );
}
}
// 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);
}
}
' 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
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
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.
