Is there an equivalent to the Scanner class in C# for strings?

Question

In Java I can pass a Scanner a string and then I can do handy things like, scanner.hasNext() or scanner.nextInt(), scanner.nextDouble() etc.

This allows some pretty clean code for parsing a string that contains rows of numbers.

How is this done in C# land?

If you had a string that say had:

"0 0 1 22 39 0 0 1 2 33 33" 

In Java I would pass that to a scanner and do a

while(scanner.hasNext())      myArray[i++] = scanner.nextInt(); 

Or something very similar. What is the C#' ish way to do this?

I'm going to add this as a separate answer because it's quite distinct from the answer I already gave. Here's how you could start creating your own Scanner class:

class Scanner : System.IO.StringReader {   string currentWord;    public Scanner(string source) : base(source)   {      readNextWord();   }    private void readNextWord()   {      System.Text.StringBuilder sb = new StringBuilder();      char nextChar;      int next;      do      {         next = this.Read();         if (next < 0)            break;         nextChar = (char)next;         if (char.IsWhiteSpace(nextChar))            break;         sb.Append(nextChar);      } while (true);      while((this.Peek() >= 0) && (char.IsWhiteSpace((char)this.Peek())))         this.Read();      if (sb.Length > 0)         currentWord = sb.ToString();      else         currentWord = null;   }    public bool hasNextInt()   {      if (currentWord == null)         return false;      int dummy;      return int.TryParse(currentWord, out dummy);   }    public int nextInt()   {      try      {         return int.Parse(currentWord);      }      finally      {         readNextWord();      }   }    public bool hasNextDouble()   {      if (currentWord == null)         return false;      double dummy;      return double.TryParse(currentWord, out dummy);   }    public double nextDouble()   {      try      {         return double.Parse(currentWord);      }      finally      {         readNextWord();      }   }    public bool hasNext()   {      return currentWord != null;   } }
