Question regarding C#

[Pete OHanlon]

When you split the string, are you wanting to split it so that "Is" is the start of the phrase or end of one?

[Rob Philpott]

Any reason for the RegEx rather than just string.Split?

Because the syntax you have to use to split on string(s) rather than character(s) is so damn clumsy: :laugh:

        string\[\] parts = input.Split(new string\[\] { " Is " }, StringSplitOptions.None);

Bad command or file name. Bad, bad command! Sit! Stay! Staaaay...

try this string s="test1 ali test2 ali"; string[] parts = s.Replace("ali", "/").Split('/');

[Pete OHanlon]

And what happens when s contains "the bestiality displayed by the main character, Ali, suggests that there is a causality at stake here"?

[Abdulnazark]

static void Main(string[] args) { String s = "aaa ali jskdfhskjdfhk ali sjkhfkjsfhkjsdh ali"; var regex = new Regex("ali", RegexOptions.IgnoreCase); var s1 = regex.Replace(s, "/"); string[] parts = s1.Split('/'); for (int i = 0; i < parts.Length; i++) Console.WriteLine(parts[i]); Console.ReadLine(); }

[Pete OHanlon]

Nope, that's still wrong. Seriously, try it out with the sentence I gave you. There's only one occurrence of the word Ali in that sentence, but "ali" appears as a substring in other words. So, you should only get two phrases - your version returns 4 and you are corrupting the string so characters are being removed.

i tried with your string 'My Name Is Ali' also and it return 'My Name Is'

[Rob Philpott]

Fair point... There is a rather obvious overload missing.

You seem to be confusing me with the original poster. My string was "the bestiality displayed by the main character, Ali, suggests that there is a causality at stake here". Try that one.

[Abdulnazark]

Now i got you, please try bellow

static void Main(string[] args)
{
String s = "the bestiality displayed by the main character, Ali, suggests that there is a causality at stake here";
string pattern = @"\bali\b";
string replace = "/";
var s1 = Regex.Replace(s, pattern, replace, RegexOptions.IgnoreCase);
string[] parts = s1.Split('/');
for (int i = 0; i < parts.Length; i++)
Console.WriteLine(parts[i]+ i.ToString());
Console.ReadLine();

    }

[Richard Deeming]

Using the Regex.Split method[^] (as OG suggested[^]) is a better solution:

string input = "the bestiality displayed by the main character, Ali, suggests that there is a causality at stake here";
string pattern = @"\bali\b";

string[] parts = Regex.Split(input, pattern, RegexOptions.IgnoreCase);
