Char String foreach

using System;
public class StringSplitForeach
{
    public static void Main()
    {
        string s = "Oh, I hadn"t thought of that";
        char[] separators = new char[] {" ", ","};
        
        foreach (string sub in s.Split(separators))
        {
            Console.WriteLine("Word: {0}", sub);
        }
    }
}

Show string in proper case

 
using System;
using System.Text;
public class StringEx
{
    public static string ProperCase(string s)
    {
        s = s.ToLower();
        string sProper = "";
   
        char[] seps = new char[]{" "};
        foreach (string ss in s.Split(seps))
        {
            sProper += char.ToUpper(ss[0]);
            sProper += 
            (ss.Substring(1, ss.Length - 1) + " ");
        }
        return sProper;
    }
}
   
class MainClass
{
    static void Main(string[] args)
    {
        string s  = "tHE test";
        Console.WriteLine("Initial String:\t{0}", s);
   
        string t = StringEx.ProperCase(s);
        Console.WriteLine("ProperCase:\t{0}", t);
    }
}

// Split and join strings. 
 
using System; 
 
public class SplitAndJoinDemo { 
  public static void Main() { 
    string str = "One if by land, two if by sea."; 
    char[] seps = {" ", ".", "," }; 
 
    // Split the string into parts. 
    string[] parts = str.Split(seps); 
    Console.WriteLine("Pieces from split: "); 
    for(int i=0; i < parts.Length; i++) 
      Console.WriteLine(parts[i]); 
    
    // Now, join the parts. 
    string whole = String.Join(" | ", parts); 
    Console.WriteLine("Result of join: "); 
    Console.WriteLine(whole); 
  } 
}

Split spaces with space

 
using System;
using System.Text;
class SplitStringApp {
    static void Main(string[] args) {
        string u = "A   B A C E   F";
        char[] sep3 = new char[] { " " };
        foreach (string ss in u.Split(sep3))
            Console.WriteLine(ss);
    }
}

using System;

Split with a list of dividers

 
using System;
using System.Text;
class SplitStringApp {
    static void Main(string[] args) {
        string t = "Once,Upon:A/Time\\In\"America";
        char[] sep2 = new char[]{" ", ",", ":", "/", "\\", "\""};
        foreach (string ss in t.Split(sep2))
            Console.WriteLine(ss);
    }
}

Split with space

 
using System;
using System.Text;

    static void Main(string[] args)
    {
        string s = "Once Upon A Time In America";
        char[] seps = new char[]{" "};
        foreach (string ss in s.Split(seps))
            Console.WriteLine(ss);
    }
}

Tokenize strings

// Tokenize strings.

    char[] seps = {" "}; 
 
    for(int i=0; i < input.Length; i++) { 
      // split string into parts 
      string[] parts = input[i].Split(seps); 
      Console.Write("Command: "); 
      for(int j=0; j < parts.Length; j++)

          Console.WriteLine(n / n2); 
          break; 
      } 
    } 
  } 
}

use the Split() method to split strings

 
using System;
class MainClass {
    public static void Main() {
        string[] myStrings = {"To", "be", "or", "not","to", "be"};
        string myString9 = String.Join(".", myStrings);
        myStrings = myString9.Split(".");
        foreach (string mySplitString in myStrings) {
            Console.WriteLine("mySplitString = " + mySplitString);
        }
    
    }
}
