Im trying to use code access security for my application, however i cant understand 
why i am not getting a security exception for the below line of code:

Dim MyPerm As New FileIOPermission(FileIOPermissionAccess.Write, "E:\Myfile1.txt") 



MyPerm.Deny() 

Dim MyFso As New System.IO.StreamWriter("E:\Myfile1.txt", IO.FileMode.OpenOrCreate) 

Dim MyString As String 
MyString = "jim " 

MyFso.Write(MyString) 


MyFso.Flush()

If i replace the above instance of MyFso by the foll line I get an exception, could 
some1 tell me why this is so.

Dim MyFso As New System.IO.StreamWriter("E:\Myfile1.txt")
