NoteThe following example demonstrates obtaining a substring from a string.
using System; public class SubStringTest { public static void Main() { string [] info = {"Name: Felica Walker", "Title: Mz.", "Age: 47", "Location: Paris", "Gender: F"}; int found = 0; Console.WriteLine("The initial values in the array are:"); foreach (string s in info) Console.WriteLine(s); Console.WriteLine("{0}We want to retrieve only the key information. That is:", Environment.NewLine); foreach (string s in info) { found = s.IndexOf(":"); Console.WriteLine(s.Substring(found + 1)); } } } // The example displays the following output to the console: // The initial values in the array are: // Name: Felica Walker // Title: Mz. // Age: 47 // Location: Paris // Gender: F // // We want to retrieve only the key information. That is: // Felica Walker // Mz. // 47 // Paris // F
