How to search for a word in a string and then get the numbers after this word?

Question

Like:

"Name: Daniel --- Phone Number: 3128623432 --- Age: 12 --- Occupation: Student"

How to get what is after "Age"? I would only like the numbers. (his age)

Answer 1

Use RegEx:

^.+Age\: ([0-9]+).+$

First grouping will return the age, see here or here.

Answer 2

Can you try a full code with following concept:

string strAge;
string myString = "Name: Daniel --- Phone Number: 3128623432 --- Age: 12 --- Occupation: Student";
int posString = myString.IndexOf("Age: ");

if (posString >0)
{
  strAge = myString.Substring(posString);
}

Robust way of doing is to get some Regular Expressions :) though...

Answer 3

Supposing that you have age in this format Age: value

string st = "Name: Daniel --- Phone Number: 3128623432 --- Age: 12 --- Occupation: Student";
//Following Expression finds a match for a number value followed by `Age:`
System.Text.RegularExpressions.Match mt = System.Text.RegularExpressions.Regex.Match(st, @"Age\: \d+");
int age=0; string ans = "";
if(mt.ToString().Length>0)
{
     ans = mt.ToString().Split(' ')[1]);
     age = Convert.ToInt32(ans);
     MessageBox.Show("Age = " + age);
}
else
     MessageBox.Show("No Value found for age");

MessgeBox show you, your string value (if found)..

Answer 4

Actually you have data, which could be easily represented as dictionary of type Dictionary<string, string>:

var s = "Name: Daniel --- Phone Number: 3128623432 --- Age: 12 --- Occupation: Student";
var dictionary = s.Split(new string[] { "---" }, StringSplitOptions.None)
                  .Select(x => x.Split(':'))
                  .ToDictionary(x => x[0].Trim(), x => x[1].Trim());

Now you can get any value from your input string:

string occupation = dictionary["Occupation"];
int age = Int32.Parse(dictionary["Age"]);
