How can I check that password is correct if I add random salt?

I'm trying to secure my c# app. I know that we MUST store password hash and salt in DB. So my question: How I can compare that password is correct if I use Random salt? (Random salt gives random values each time). I also have the code below

 public static string HashPassword(string p, string s)
    {
        var combinedPassword = String.Concat(p, s);
        var sha256 = new SHA512Managed();
        var bytes = UTF8Encoding.UTF8.GetBytes(combinedPassword);
        var hash = sha256.ComputeHash(bytes);
        return Convert.ToBase64String(hash);
    }
public static String GetRandomSalt()
{
    var random = new RNGCryptoServiceProvider();
    var salt = new Byte[1024];
    random.GetBytes(salt);
    return Convert.ToBase64String(salt);
}

I am open to other suggestions in general.

First , you have to get salt in database by username , then hash it with posted password , finally compare it to password stored in database
