FileIOPermission Class

Definition

The FileIOPermission class controls the ability to access files and folders.

Remarks

The FileIoPermission class is designed to check permissions for specific APIs. For a list of all APIs that are protected by permissions, see Secured APIs. Before the protected API is run, you must call the assert method on the same tier, usually the server tier, that the corresponding CodeAccessPermission::demand method is called on. Call a method on the server tier from one of the following:

  • A server static method
  • A class instance method that is set to run on the server by using the RunOn class property

The following code example shows a new instance of the FileIoPermission class that specifies read access for the File.txt file. The assert method is called to declare that the code can then call the AsciiIo.new method.

server static void main(Args args) 
{ 
    FileIoPermission _perm; 
    AsciiIo a; 
    _perm = new FileIoPermission("c:\\File.txt",'r'); 
    _perm.assert(); 
    // Invoke the protected API. 
    a = new AsciiIo("c:\\File.txt",'r'); 
}
