regex problem

yokzu

Hi,
I'm using regex in our project. How can I check 2 strings in a sentence?

For example like below, if a sentence has "is" and "sentence" words, I want to choose it.

"this is a test sentence"

How can I do this?

regards.

try like this

var sentance = textBox1.Text;
if (Regex.IsMatch(sentance, @"^ABCD-5-DCEG:\s.*\b(DOWN|down)\b"))
{
MessageBox.Show("Valid");
}

i have written for the example you have give in your post "this is a test sentence"

now you have asking different expression.

Try:

string s = "ABCD-5-DCEG: Process 111, Nbr 1.1.1.1 on from FULL to DOWN, Neighbor Down:";
string r = @"^ABCD-5-DCEG:\W.*\bDOWN\b";
bool b = Regex.IsMatch(s, r);
Console.WriteLine(b); // True

Hi Iftikar,
I tryed your code too but it didnt work.

Sorry maybe I write the wrong example.

"ABCD-5-DCEG: Process 111, Nbr 1.1.1.1 on from FULL to DOWN, Neighbor Down:"

The example is like above.

I want to choose if starts with "ABCD-5-DCEG:" and contain "DOWN" words.

Hi yokzu,

read it like this:

(\bWORD1\b)(?:[^.]|\.\s)*(\bWORD2\b)

It will work, tested solution.

Hi yokzu,

use this regex:

(\bis\b)(?:[^.]|\.\s)*(\bsentence\b)

Happy Coding :)
Cheers!
