title: string split by index / params?
body: <p>Just before I write my own function just wanted to check if there exists a function like  <code>string.split(string input, params int[] indexes)</code>  in the .NET library?
  This function should split the string on indexes i pass to it.</p>
  
  <p>Edit: I shouldn't have added the string.join sentence - it was confusing.</p>
