  char[] separator,
  int count,
  StringSplitOptions options

• separator - An array of Unicode characters that delimit the substrings in this string, an empty array that contains no delimiters, or null.
• count - The maximum number of substrings to return.
• options - StringSplitOptions.RemoveEmptyEntries to omit empty array elements from the array returned; or StringSplitOptions.None to include empty array elements in the array returned.

Example

This example demonstrates the String() methods that use the StringSplitOptions enumeration.

using System;/*w  ww .  j  a v  a  2  s .  com*/

class Sample 
{
    public static void Main() 
    {
        string s1 = ",ONE,,TWO,,,THREE,,";
        char[] charSeparators = new char[] {','};
        string[] result;
    
        result = s1.Split(charSeparators, 2, StringSplitOptions.None);
        Show(result);

    }

    public static void Show(string[] entries)
    {
        Console.WriteLine("The return value contains these {0} elements:", entries.Length);
        foreach (string entry in entries){
           Console.Write("<{0}>", entry);
        }
    }
}

The code above generates the following result.
