Substring of a string from the end of the string

I need to get the words from the end of a string. For example:

string1 = "Hello : World";
string2 = "Hello : dear";
string3 = "We will meet : Animesh";

I want output for 

string1 = "World"
string2 = "dear"
string3 = "Animesh"

I want the word after the :.

Regular Expressions is a good way to parse any texts and extract out what is needed:

Console.WriteLine (
   Regex.Match("Hello : World", @"[^\s]+", RegexOptions.RightToLeft).Groups[0].Value);

This method will work, unlike the other responses, even when there is no :.

You can use Split

string s = "We will meet : Animesh";
string[] x = s.Split(':');
string out = x[x.Length-1];
System.Console.Write(out);

Update in response to OPs' comment.

if (s.Contains(":"))
{
  string[] x = s.Split(':');
  string out = x[x.Length-1];
  System.Console.Write(out);
}
else
  System.Console.Write(": not found");

Various ways:

var str = "Hello : World";
var result = str.Split(':')[1];
var result2 = str.Substring(str.IndexOf(":") + 1);

EDIT:

In response to your comment. Index 1 won't be available for a string that does not contain a colon character. You'll have to check first:

var str = "Hello World";
var parts = str.Split(':');
var result = "";
if (parts.Length > 1)
    result = parts[1];
else
    result = parts[0];

Try this

string string1 = "Hello : World";
string string2 = "Hello : dear";
string string3 = "We will meet : Animesh";

string1 = string1.Substring(string1.LastIndexOf(":") + 1).Trim();
string2 = string2.Substring(string2.LastIndexOf(":") + 1).Trim();
string3 = string3.Substring(string3.LastIndexOf(":") + 1).Trim();
