Can anyone help me to create DES decryption algorithm by using ECb mode.

I want to achieve the same functionality like this guy does.
http://www.emvlab.org/descalc/
Key:- 0123456789ABCDEF0123456789ABCDEF
input data:- 1214F1DE3FA3C46B
Slect ECB radio button and click "Decrypt"
output should be: 6CF24D434FB78E13


I need programming logic/code(any language, C# preferred) for this algorithm.
any help would be appreciated.

Thanks.
