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•2y ago

var lastCharacter = ccal[^0];

var lastCharacter = ccal[^0];

FSHFOP•2y ago

yes

Pobiega•2y ago

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

JakenVeina•2y ago

is it ^1 or ^0? k

Pobiega•2y ago

^0 is oob

JakenVeina•2y ago

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

FSHFOP•2y ago

Pobiega•2y ago

are you using an old .NET version?

FSHFOP•2y ago

Pobiega•2y ago

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

FSHFOP•2y ago

whats the latest?

Pobiega•2y ago

.NET 7

FSHFOP•2y ago

how do i check

Pobiega•2y ago

open your .csproj file

FSHFOP•2y ago

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

Pobiega•2y ago

Yeah you are 100% using .net framework.

FSHFOP•2y 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•2y ago

you picked one of the "NO" options

FSHFOP•2y ago

is there a solution to it

Pobiega•2y 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

FSHFOP•2y ago

will try

FSHFOP•2y ago

Does it matter which i choose

Pobiega•2y ago

6 .net 6

FSHFOP•2y ago

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

Pobiega•2y ago

no only the .cs files

FSHFOP•2y 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•2y ago

no because llcal will be a char

FSHFOP•2y ago
