How to decrypt a file by using the "DES/CBC/PKCS5Padding" method?

Hello,

I have the encrypted file that used the "Cipher.getInstance("DES/CBC/PKCS5Padding");"  for DES Encryption and I want to decrypted that file using the same method using DES Algorithm,  CipherMode.CBC and PaddingMode.PKCS5.  How do I do it? Can anybody give me a sample in C# code?  Thanks and really appreciated!
