i want to get post digits from "KB"(Actual data size)
for example
string word1="Product data 5KB per second"
string word2="Product data is 5 KB per hour"
i want to extract 5 from the above words if i pass KB
This Regex should work
var word2Size = Regex.Match(word2, #"\d+(?=\s?KB)").Value;
or for floating point numbers
var word2Size = Regex.Match(word2, #"\d+\.?\d+(?=\s?KB)").Value;
it should return a numeric value immediately preceding optional whitespace followed by KB
You could generate a regex string for different suffix with :
string regexString = String.Format(#"\d+\.?\d+(?=\s?{0})", mySuffix);
var word2Size = Regex.Match(word2, regexString).Value;

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 have a string like this
4366|2d53|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|3f80|0|4248|295f|41c4|19c4|0|268
Here,
| - is denoted as a divider i want to make each divider consists exactly 4 charcters
Ex: 0|0 this must to be simplified as 0000|0000
12|13 this must to be simplified as 0012|0013
Note:
if the char. enclosed with | is less then 4 then add zero in front of the characters i.e. 12|13 is simplified as 0012|0013 not like this 1200|1300
Result:
4366|2d53|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|3f80|0|4248|295f|41c4|19c4|0|268
i want to convert this as
4366|2d53|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|0000|3f80|0000|4248|295f|41c4|19c4|0000|2680
That can be solved with simple string operations Split(), PadLeft() and Join()
string input = "4366|2d53|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|0|3f80|0|4248|295f|41c4|19c4|0|268";
string result = string.Join("|",input.Split('|').Select(x => x.PadLeft(4, '0')));
Something like this should work:
string.Join("|", myString.Split('|').Select(x => x.PadLeft(4,'0')));

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 want to get the previous chars from a certain char in a string.
For example: myString = "26+", so I want to get 26 without +. How can I do this?
Use Substring and IndexOf.
string str = "26+";
string requiredString = str.Substring(0, str.IndexOf('+'));
strings are immutable in C# and you have to assign the results to string itself or some other string.
The function String.Substring will do what you need.
yourString.Substring(0, keepCharactersBeforeHere);
