You could do so in a few lines of python:
Which outputs the WIF as:
Code:
import os, binascii, hashlib, base58
fullkey = "80"+"7542FB6685F9FD8F37D56FAF62F0BB4563684A51539E4B26F0840DB361E0027C"
sha256a = hashlib.sha256(binascii.unhexlify(fullkey)).hexdigest()
sha256b = hashlib.sha256(binascii.unhexlify(sha256a)).hexdigest()
WIF = base58.b58encode(binascii.unhexlify(fullkey+sha256b[:8]))
print(WIF)

It's a Bitcoin private/public key and address library coded in C#. Seems fairly complete.
Note that I haven't personally tested this, but it should at least point you in the right direction

I want to convert a randomly generated 256 bitcoin address into WIF. I have following step by step instructions that i am trying to implement into C# but could not do so yet. the biggest problem is conversion of string into base58. Can somebody help me do this
1.) Take a private key (Below is the HEX representation of binary value)

2.) Add a 0x80 byte in front of it
807542FB6685F9FD8F37D56FAF62F0BB4563684A51539E4B26F0840DB361E0027C
3.) Perform SHA-256 hash on the extended key
$ echo -n '807542FB6685F9FD8F37D56FAF62F0BB4563684A51539E4B26F0840DB361E0027C' | xxd -r -p | sha256sum -b

4.) Perform SHA-256 hash on result of SHA-256 hash
$ echo -n '7DE4708EB23AB611371BB778FC0C8BDE80394AB2D8704D7129FB5771E2F1730D' | xxd -r -p | sha256sum -b

5.) Take the first 4 bytes of the second SHA-256 hash, this is the checksum
CD5C4A8E
6.) Add the 4 checksum bytes from point 5 at the end of the extended key from point 2

7.) Convert the result from a byte string into Base58 to get it into the Base58Check format. This is also known as the Wallet Import Format
