well, we commonly use string interpolation anyway

TheRanger

REPL Result: Success

string name = "test";
Console.WriteLine($"HENLO {name}!");

string name = "test";

i see ur issue anyway you wrote O not 0

O // this is an O
0 // this is a 0

O // this is an O
0 // this is a 0

Masimos•12mo ago

how did i do Smadge

is string interpolation anyways?

TheRanger•12mo ago

heres an example

MODiX•12mo ago

TheRanger

REPL Result: Success

string name = "test";
Console.WriteLine("HENLO {name}!");
Console.WriteLine($"HENLO {name}!");

string name = "test";
Console.WriteLine("HENLO {name}!");
Console.WriteLine($"HENLO {name}!");

Console Output

HENLO {name}!
HENLO test!

HENLO {name}!
HENLO test!

TheRanger•12mo ago

basically it converts the variable in between {} into its value you'd need to put $ before the first quotation of the string in order to activate it, just like in the example

Masimos•12mo ago

and what is the difrence between that and

Console.Writline("Henlo{0}",name)

Console.Writline("Henlo{0}",name)

ero•12mo ago

It's shorter and can be used anywhere in any string $interpolation

MODiX•12mo ago

String interpolation is the preferred way of building strings in C#. It is easier to read than concatenation. For example:

var foo = 1;
var bar = 2;
Console.WriteLine("foo is equal to: " + foo + " and bar is equal to: " + bar);

var foo = 1;
var bar = 2;
Console.WriteLine("foo is equal to: " + foo + " and bar is equal to: " + bar);

can be written as:

var foo = 1;
var bar = 2;
Console.WriteLine($"foo is equal to: {foo} and bar is equal to: {bar}");

var foo = 1;
var bar = 2;
Console.WriteLine($"foo is equal to: {foo} and bar is equal to: {bar}");

👍

TheRanger•12mo ago

and more readable

ero•12mo ago

Also more performant actually

Masimos•12mo ago

how do you use the modx bot

TheRanger•12mo ago

$eval

MODiX•12mo ago

To compile C# code in Discord, use !eval Example:

!eval for(int i = 0; i < 4; i++) Console.WriteLine(i);

!eval for(int i = 0; i < 4; i++) Console.WriteLine(i);

Please don't try breaking the REPL service. Also, remember to do so in #bot-spam!

TheRanger•12mo ago

!e also works

Masimos•12mo ago

TheRanger•12mo ago

read the example u need to provide code

Masimos•12mo ago

ohh and can you see the output anyvere

TheRanger•12mo ago

what do you mean?

Masimos•12mo ago

like start that code and see the output here

TheRanger•12mo ago

it outputs at where you executed the code so if you ran your code here, it will output here if your trying to display the output into a different server, i dont think it will work

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
