Generate address of 'private key' from user input

I want to take a private key as input from the user and convert it to a wallet address using C#.

I have seen this in a tutorial to generate a random key:

Key privateKey = new Key();
PubKey publicKey = privateKey.PubKey;
Console.WriteLine(publicKey.GetAddress(ScriptPubKeyType.Legacy, Network.Main));

How do I convert a private key string from the user to a wallet address for main net?
