clone

Instead of removing last number i would like to clone, how?

        private void btnpocl(object sender, EventArgs e)
        {

            if (ccal.Length > 0)
            {
                ccal = ccal.Remove(ccal.Length - 1, 1);
            }

            txtbout.Text = ccal;
        }

        private void btnpocl(object sender, EventArgs e)
        {

            if (ccal.Length > 0)
            {
                ccal = ccal.Remove(ccal.Length - 1, 1);
            }

            txtbout.Text = ccal;
        }

ccal is a string here, right?

JakenVeina•15mo ago

var lastCharacter = ccal[^0];

var lastCharacter = ccal[^0];

FSHF•15mo ago

yes

Pobiega•15mo ago

var last = ccal[^1]; ^1 is correct

JakenVeina•15mo ago

is it ^1 or ^0? k

Pobiega•15mo ago

^0 is oob

JakenVeina•15mo ago

I've had virtually 0 opportunity to use that syntax since it was added

"clone" and "copy" are very much not the words to use for this

FSHF•15mo ago

Pobiega•15mo ago

are you using an old .NET version?

FSHF•15mo ago

the latest nvm

Pobiega•15mo ago

You could still have picked .net framework during project creation, even if you made it a day ago.

FSHF•15mo ago

whats the latest?

Pobiega•15mo ago

.NET 7

FSHF•15mo ago

how do i check

Pobiega•15mo ago

open your .csproj file

FSHF•15mo ago

CS8370 Feature 'index operator' is not available in C# 7.3. Please use language version 8.0 or greater. C

Pobiega•15mo ago

Yeah you are 100% using .net framework.

FSHF•15mo ago

Pobiega•15mo ago

When creating a new project, prefer using .NET over .NET Framework, unless you have a very specific reason to be using .NET Framework. .NET Framework is now legacy code and only get security fix updates, it no longer gets new features and is not recommended. https://cdn.discordapp.com/attachments/569261465463160900/899381236617855016/unknown.png

Pobiega•15mo ago

you picked one of the "NO" options

FSHF•15mo ago

is there a solution to it

Pobiega•15mo ago

Create a new project and copy your stuff over most of it will likely work with little changes, since its a new project and you are still a beginner

FSHF•15mo ago

will try

FSHF•15mo ago

Does it matter which i choose

Pobiega•15mo ago

6 .net 6

FSHF•15mo ago

can i just copy and paste over the folder and files for it to work?

Pobiega•15mo ago

no only the .cs files

FSHF•15mo ago

                var lccal = ccal[^1];
                double ans = Math.Pow(lccal, 2);
                ccal += ans.ToString();

                var lccal = ccal[^1];
                double ans = Math.Pow(lccal, 2);
                ccal += ans.ToString();

would this be right for doing power of 2 on the last number

Pobiega•15mo ago

no because llcal will be a char

FSHF•15mo ago

is there a way to remove first instead of last?
