What does Remove do?

asianaf•2y ago

it removes the word in that Text or string

mtreit•2y ago

https://learn.microsoft.com/en-us/dotnet/api/system.string.remove?view=net-7.0

String.Remove Method (System)

Returns a new string in which a specified number of characters from the current string are deleted.

mtreit•2y ago

Strings are immutable.

asianaf•2y ago

like this right?

mtreit•2y ago

Remove produces a new string. You aren't looking at the return value though. You are calling Remove and throwing away the result.

asianaf•2y ago

so I still need to grab it?

mtreit•2y ago

You need to assign the result to something, yes.

or could I just add it to lbloutput?

asianaf•2y ago

like this

mtreit•2y ago

Yes you can do that as well.

asianaf•2y ago

oh this stuff is getting hard

asianaf•2y ago

another question how do I remove the starting number/word?

mtreit•2y ago

That line of code you wrote where you are doing everything in one line: I avoid writing code like that. I think it's better to break up each task you are doing into smaller tasks and then put them all together. Then it's easier to debug and to reason about what's going on in each line of code. Which starting number ?

asianaf•2y ago

if you look at the image 980529 I'm trying to remove 9

mtreit•2y ago

You can use string.Substring

MODiX•2y ago

mtreit#6470

REPL Result: Success

var s = "980529";
s = s.Substring(1);
Console.WriteLine(s);

var s = "980529";
s = s.Substring(1);
Console.WriteLine(s);

Console Output

Compile: 514.484ms | Execution: 64.253ms | React with ❌ to remove this embed.

asianaf•2y ago

OOh okay I did it like this

asianaf•2y ago

doesn't T start as 0? like Thompson 01234567

mtreit•2y ago

Yes, "T" is at index 0 in the string "Thompson" if that's what you're asking. I'm not sure I understood the question.

asianaf•2y ago

sorry for the bad english but yeah that's what I'm trying to sya say then could I do Remove(0)?

mtreit•2y ago

Returns a new string in which all the characters in the current instance, beginning at a specified position and continuing through the last position, have been deleted.

If you read that definition, what does it mean to pass 0? In other words: "Start at position zero and delete everything from that position to the end of the string." So passing zero deletes everything. If you're not sure what a method does, you should definitely read the documentation for it:
