binary array shifting

hi everybody,

i am using encryption and decryptionin with RSA and symmectric algo aes in which

i have to shift byte to right and i m using that code in VB.Net

dim keyex(machine.shift.right(rsa.keysize,3) as byte
byte[] keyex(rsa.ketsize >> 3) as byte in c#

and i m getting error at word machine which is machine is not declared .
so i want to know that is there any class for machine.shift.right or how can i use machine class in vb.net

or is there any another way of doing which is this line machine.shift.right is doing

plz solve my problem
i would be very thankful to you

I gather from this that you tried a c# to vb.net converter

if rsa.keysize is an unsigned integer than you are out of luck because vb.net doesn't support them (they will in the 2005 version though http://lab.msdn.microsoft.com/vs2005/.)

if rsa.keysize isn't an unsigned integer then you can just do
rsa.keysize >> 3

sir,

i would like to thank you a lot for taking intrest in my problem.

the first solution which you have provided i:e to use "rsa.keysize >> 3" so i tried

Dim keyex(rsa.KeySize >> 3) As Byte

although this is not giving any compilation error but it gives a runtime error saying

ERROR : offset and lenght were out of bounds for the array or count is greater than number of elements from index to end of the source collection

---------------------------------------------------------------------------------------------

now sir i am trying your second solution that is with namespace.
so give me just few minutes so i'll get back to you
