I generally like to use my own extension for that   string data    THExxQUICKxxBROWNxxFOX   var dataspt   data Split  xx       gt THE  QUICK  BROWN  FOX      the extension class must be declared as static public static class StringExtension          public static string   Split this string str  string splitter                return str Split new     splitter    StringSplitOptions None             This will however lead to an Exception  if Microsoft decides to include this method-overload in later versions  It is also the likely reason why Microsoft has not included this method in the meantime  At least one company I worked for  used such an extension in all their C  projects   It may also be possible to conditionally define the method at runtime if it doesn t exist

The previous answers are all correct  I go one step further and make C  work for me by defining an extension method on String   public static class Extensions       public static string   Split this string toSplit  string splitOn            return toSplit Split new string     splitOn    StringSplitOptions None             That way I can call it on any string in the simple way I naively expected the first time I tried to accomplish this    a big long string with stuff to split on  Split  g str

There is an overload of Split that takes strings    THExxQUICKxxBROWNxxFOX  Split new       xx     StringSplitOptions None     You can use either of these StringSplitOptions   None  - The return value includes array elements that contain an empty string     RemoveEmptyEntries - The return value does not include array elements that contain an empty string   So if the string is  THExxQUICKxxxxBROWNxxFOX   StringSplitOptions None will return an empty entry in the array for the  xxxx  part while StringSplitOptions RemoveEmptyEntries will not
