One-line anonymous method

I have a question. Consider that scenerio:

    public override string Encrypt(string input)
    { 
        Func<char, char> encryption = (c) => (char)chars[(c * k1 + k0) % 26]; 

        string result = string.Empty;
        foreach(char c in input)
            result += encryption(c);

        return result;
    }

My question is, can we change that result += encryption(c) line into something like in Func<char, char> declaration? Can we write this anonymous method in one line?

Not that it's very readable, but here is whole method simplified to one line:

public override string Encrypt(string input) => string.Concat(input.Select(c => (char)chars[(c * k1 + k0) % 26]));

You can try using Linq, i. e.

public override string Encrypt(string input)
{ 
    Func<char, char> encryption = (c) => (char)chars[(c * k1 + k0) % 26]; 

    return string.Concat(input.Select(c => encryption(c)));
}

We can even get rid of encryption:

public override string Encrypt(string input) => 
   string.Concat(input.Select(c => (char)chars[(c * k1 + k0) % 26]));

You can do something like this: 

result = string.Concat(input.Select(c => encryption(c)))
