How can I extract the word "Word" (or any word) using Regex into a string in both cases? in the following string:
Word = CreateObject(980, -1696.5996, -12.2998, 5.3, 0, 0, 317.999);
MoveObject(Word, -1660.9004, 79.40039, 2.2,6);
I am pretty new in Regex, and I am having hard time understanding the tutorials over the internet.
I have tried using /(.*)( = CreateObject)/ but no luck
Tried using /MoveObject\(.*?\,/ and it works, but it matches MoveObject too, and I want it to match only "Word"
Thanks!


You could try the below regex.
#".*?(?= = CreateObject)|(?<=MoveObject\().*?(?=,)"
OR
#"\S+?(?= = CreateObject)|(?<=MoveObject\().*?(?=,)"

I would like to exclude a specific string when it is contained in an expression:
Example:
myurl.htm = exclude
myurl = include
I tried this one : ([a-z0-9]+)(?!.htm)
But looks like it doesn't work.

Try the following:
([a-z0-9]+)(?!^\.htm)
You had two errors in your expression:
You have to escape the dot . with a backslash because it means "matches any character (except newline)" unescaped.
You have to add a ^ to prevent cutting of the last character.
You can test your expression on this website: https://regex101.com/

I though it was simple. but I didn't manage to make this line of code add "\Game_Progress.xml" to my String
code_file.Insert(code_file.Length, "\\Game_Progress.xml");

You can append the string using the += operator:
code_file += "\\Game_Progress.xml";
Note: If you want to combine a path, you should consider using the Path Combine method:
System.IO.Path.Combine(code_file, "\\Game_Progress.xml")

C# can require an #prior to the string when using backslashes. Try:
code_file.Insert(code_file.Length, #"\\Game_Progress.xml");

I have to validate a sting with regular expression.
String Should be in the NHCC-XXXXX-00 Format ,where X is a Number.
Correct strings:
NHCC-10010-00,
NHCC-78965-00,
NHCC-99654-00
Wrong strings:
NHCC-1001-00
NHCC-78965-0
NHC-99654-00
ASDF-99654-00
NHCC-F9654-00
NHCC-99654-01
Can any one help me to solve the above senario?

This should work:
"NHCC-\d{5}-00"
Demo

You need to use anchors inorder to do an exact match.
#"^NHCC-\d{5}-00$"

The regular expression you want is #"(?s)^NHCC-\d{5}-00$"
if (!Regex.IsMatch(input, #"(?s)^NHCC-\d{5}-00$"))
{
//not valid
}

I have a large text. I need find any word in the text then copy to variable the phrase that contains the word. How can I do this by C#? Maybe I can use some regular expression?

Use the regex expression [^.!?;]*(search)[^.?!;]*[.?!;], where "search" is your query.
string query = "professional";
var regex = new Regex(string.Format("[^.!?;]*({0})[^.?!;]*[.?!;]", query));
string text =

var results = regex.Matches(text);
for (int i = 0; i < results.Count; i++)
Console.WriteLine(results[i].Value.Trim());
This code uses the regex to find all sentences containing "professional", and outputs them, trimming any whitespace.
