Hi guys/girls,

I have one textbox in what clients will write some text like short message.

And it accepts letters, numbers etc.. and thats what I need.
Now, my problem is I need to take numbers from writtent messages and use is for something else.

possible sc :
string message = "My ticket number is : 1005"

string message = "Ticket 1005 is my ticket number"

string message = "Ticket number 1005 and I want to link it"

and so on.. i tryed few thing but none worked. Can you point me to right direction.

Thank You.

What I have tried:

foreach(char ch in TextBox1.Text)
{
if(!char.IsDigit(ch))
{
TextBox1.Text = "True";
}
{
TextBox1.Text = "False";
}
}

It's possible, and probably the easiest way - though it may not seem like it - is to use a Regex:
string message = "My ticket number is : 1005";
int value;
Match m = Regex.Match(message, @"\d+");
if (m.Success)
    {
    value = int.Parse(m.Value);
    Console.WriteLine(value * 2);
    }
The string \d+ is a regular expression for "a sequence of digits".

Use Regular expresssion like below:

var resultString = Regex.Match(message, @"\d+").Value;

Console.WriteLine(resultString);
