using System; public class TestConsoleApp { public static void Main(string[] args) { string s = string.Format("123"); string t = string.Format("{0}", 123); string u = string.Format("{0:D3}", 123); Console.WriteLine(s); Console.WriteLine(t); Console.WriteLine(u); } }

Format a string
using System; using System.Collections.Generic; using System.Text; class Program { static void Main(string[] args) { int theInt = 90; double theDouble = 9.99; bool theBool = true; Console.WriteLine("Int is: {0} Double is: {1} Bool is: {2}",theInt, theDouble, theBool); } }
Fill placeholders using an array of objects.
using System; using System.Collections.Generic; using System.Text; class Program { static void Main(string[] args) { object[] stuff = { "Hello", 20.9, 1, "There", "83", 99.99933 }; Console.WriteLine("The Stuff: {0} , {1} , {2} , {3} , {4} , {5} ", stuff); Console.WriteLine("{0}, Number{0}, Number{0}", 9); } }
Use the static String.Format() method to build a new string.
using System; using System.Collections.Generic; using System.Text; class Program { static void Main(string[] args) { string formatStr; formatStr = String.Format("Don't you wish you had {0:C} in your account?", 99989.987); Console.WriteLine(formatStr); } }
use the Format() method to format a string
using System; class MainClass { public static void Main() { float myFloat = 1234.56789f; string myString8 = String.Format("{0, 10:f3}", myFloat); Console.WriteLine("String.Format("{0, 10:f3}", myFloat) = " + myString8); } }
Compare two strings with StringComparison.CurrentCultureIgnoreCase
using System; public static class StringExtensions { public static bool EqualsIgnoreCase(this string me, string them) { return me.Equals(them, StringComparison.CurrentCultureIgnoreCase); } }
Check if a String contain another string by ignoring case
using System; public static class StringExtensions { public static bool ContainsIgnoreCase(this string me, string other) { return me.ToLower().Contains(other.ToLower()); } }
