I've got a bit of a challenge. I have a string which contains of 11 characters, the first 10 denotes an amount, and the last one is a letter or special letter, which represents a value to add.
For example if I got
0000000400A
this means
400 + 2
So the result should be
402
I can't figure out how to do this. Any ideas?
Something like this?
// Setup
var dict = new Dictionary<char, int>();
dict.Add('A', 2);
dict.Add('B', 3);
dict.Add('C', 4);
dict.Add('D', 5);
var str = "0000000400A";
// This is what you need
var result = Convert.ToInt32(str.Substring(0, 10)) + dict[str[10]];
Console.WriteLine(result);

I am a novice in this programming language so now I have a few problems. I have a bill where I need it to find the "/" character and then the string must be automatically carriage return
For example, I have the following string of characters:
BL4444 / BL5555 / BL6666
I need it to be:
BL4444 /
BL5555 /
BL6666
Replace / (slash and space) with / and new line:
String.Replace and Environment.NewLine:
var str = "BL4444 / BL5555 / BL6666";
str = str.Replace("/ ", "/" + Environment.NewLine);

how to split this string on every 500 values ending in comma
string val= "1,2,3,4,5,.....................,2000,2001";
//Solution
[1,2,3,...,500]
[501,502,503,...,1000]
[1001,1002,...,1500]
You can match the string with the following regex instead (where 499 is 500 minus 1):
(?:[^,]+,){0,4}[^,]+
Demo (for splitting at every 5 commas here): https://regex101.com/r/nbRxdv/2
Assuming by "no loops" you mean you're happy to let LINQ use loops internally, maybe something like this:
string s = "your,comma,string";
string[] ss = s.Split(',');
Print500(ss, 0);
private void Print500(IEnumerable<string> ies, int skip)
{
if (skip > ies.Count())
return;
Console.Out.WriteLine(string.Join(",", ies.Skip(skip).Take(500)));
Print500(ies, skip + 500);
}
I haven't run it, so it might have some minor issues..

My String: draw.text("hello",11,22);
Need Output: 11
So i need to get a String Between first , character and Last , character.
Its not duplicate question.I not found same questions.
I need to get the 2nd argument in my string,the string between first , and last , in string
Split your string on the , character, remove the first and last item, and join the remaining components back together:
var input = "draw.text(\"hello\",11,22);";
var components = input.Split(',');
var result = String.Join(",", components.Skip(1).Take(components.Length - 2));
// yields 11
Note: using System.Linq is required for Skip and Take.

I want to generate number as format above and I try to use UUID() and GUID() but it is not what I want(difference format and it is hexadecimal not number)
anyone have any idea or logic to do it?
The simplest way to generate 1000000000000 unique numbers is just an ever-increasing sequence:
long i = 42; // whatever
string key = $"{i / 100000000:0000}-{(i / 10000) % 10000:0000}-{i % 10000:0000}";
The next time, increase i before generating the key.

I usually never use char so sorry if it seems a noob question. I'm doing a Crypter, and wanted to do "if there's at least 4 differents char, then crypt, else don't crypt and return error"
Actual Code:
string msg = Console.ReadLine();
char[] msgToChar = msg.ToCharArray();
if(here is the problem)
{
Console.WriteLine("Crypted message: " + Crypt(msg.ToUpper()));
}
else
{
Console.WriteLine("Please enter at least 4 differentes characters.");
}
You could do this to get the distinct count of characters.
msgToChar.Distinct().Count()
So your if would be something like
if (msgToChar.Distinct().Count() >= 4)
