Substring multiple lines of text

I have a text file containing these words:

Name: Bob

Age: 3

and my c# code is:

string text = File.ReadAllText("path to a.txt");

How do i substring this so that i could get the value 3 and Bob?

Assuming that you're reading your data from a file, then this should work nicely:

Dictionary<string, string> pairs =
    File
        .ReadAllLines(@"50780830.txt")
        .Select(l => l.Split(':'))
        .Where(xs => xs.Length == 2)
        .Where(xs => !String.IsNullOrEmpty(xs[0].Trim()))
        .ToDictionary(xs => xs[0].Trim(), xs => xs[1].Trim());

Console.WriteLine(pairs["Name"]);
Console.WriteLine(pairs["Age"]);

When I run this I get:

Bob
3

You can try this with only one line:

IEnumerable<String> list = str.Split('\n').Select(s => s.Split(':')[1]);

The first split meaning is to isolate each row. The second split meaning is to take the word after ':'.

You can achieve this by using Split and Substring function just like this:

String str = "Name: Bob\r\n\r\nAge: 32";
String Name = str.Split(new String[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries)[0];
Name = Name.Substring(Name.IndexOf(':') + 1).Trim();
String Age = str.Split(new String[] { "\r\n" }, StringSplitOptions.RemoveEmptyEntries)[1];
Age = Age.Substring(Age.IndexOf(':') + 1).Trim();
Console.WriteLine(Name + "," + Age);
