The following doesn't use any string functions (not even ToLower) though it needs a lot more code and is not as easy to understand as the other solutions : using System; using System.Collections.Generic; using System.Text; using System.Linq; class Program { static void Main() { string text = you just kidding me for me hell of a sake dude ha for me; string temp = ; string temp2 = ; List words = new List (); List separators = new List (); List tokens = new List (); bool sepStarts = false; // whether text starts with a separator bool sepEnds = false; // whether text ends with a separator // separate string into words and separators for(int i = 0; i { char c = text[i]; if ((c >= 'a' && c = 'A' && c = '0' && c { temp += c; if (temp2 != ) { separators.Add(temp2); temp2 = ; } } else { if (i == 0) sepStarts = true; temp2 += c; if (temp != ) { words.Add(temp); temp = ; } } } if (temp != ) words.Add(temp); if (temp2 != ) { separators.Add(temp2); sepEnds = true; } // get distinct words and add them and any preceding separator to tokens list int s = 0; if (sepStarts) s = 1; for(int i = 0; i { bool distinct = true; for(int j = 0; j { if (words[i].Length == tokens[j].Length) { bool same = true; for(int k = 0; k { char c = words[i][k]; char c2 = tokens[j][k]; if (c >= 'a' && c { if ((c != c2) && (c != c2 + 32)) { same = false; break; } } else if (c >= 'A' && c { if ((c != c2) && (c != c2 - 32)) { same = false; break; } } else if (c == '_' || c == '-' || c == '\'') { if (c != c2) { same = false; break; } } } if (same) { distinct = false; break; } } } if (distinct) { if (s >= 1) tokens.Add(separators[s - 1]); tokens.Add(words[i]); } s++; } if (sepEnds) { tokens.Add(separators[separators.Count - 1]); } // assemble tokens list into string temp = ; for(int i = 0; i { temp += tokens[i]; } Console.WriteLine(temp); Console.ReadKey(); } }

You can do this way as well but there is an empty space left behind the removed characters. Is there any idea to reformat the output so that empty space will be removed? using System; using System.Text; class Program { static void Main() { StringBuilder builder = new StringBuilder(you just kidding me for me hell of a sake dude ha for me); builder.Remove(24 2); builder.Remove(48 3); Console.WriteLine(builder); Console.ReadKey(); } } /* you just kidding me for hell of a sake dude ha me */ For additional information see http://www.dotnetperls.com/stringbuilder

try this: string RTBstring = you just kidding me for me hell of a sake dude ha for me; string duplicatesRemoved = string.Join(  RTBstring.Split(' ').Distinct());

Ty for reply friends .. Humm with generic's it can be done yes :) If possible provide me solution for it & i also possible provide manual solution its most helpful in my future .. TY mate Sanjeeb Lenka can this be done with out using any in-build functions :)
