generating GUID without hyphen

I am creating a GUID with the following piece of code

 byte[] keyBytes = Encoding.UTF8.GetBytes(Guid.NewGuid().ToString("N").Substring(0, 9));

The end result is a GUID that contains lower cased chars and numbers. I am trying to have upper case, lower case and numbers, all in one GUID. And I dont want hyphen char within the generated GUID. Can anyone suggest me an idea?

Concerning your comment:

i just wish to generate a random guid value with upper, lower and
numbers…

Something like this could be done

var rand = new Random();
var sb = new StringBuilder();

foreach (char c in Guid.NewGuid().ToString("N"))
{
    sb.Append(rand.Next(0, 2) == 1 ? Char.ToUpper(c) : c);
}

Not giving any guarantees about the quality about the “randomness” of upper/lowercase characters.
