[Mono-list] string expansion

[Fabrício]

I look for anything like String.cs, in svn://anonsvn.mono-project.com/source/trunk/mono,  to submit my own methods do expands the String class, but I don't found...

I have methods like these:

  /// <summary>
  /// Counts how many occurrences of the specified Unicode character in current string.
  /// </summary>
  /// <param name="value">A Unicode character to count.</param>
  /// <returns>Result of number of found occurrences.</returns>
  public int CountOf(char value)
  {
   if (this.Length == 0)
    return 0;

   int count = 0;
   foreach (char c in this)
    if (c == value)
     count++;
   return count;
  }

  /// <summary>
  /// Counts how many occurrence of the specified string in current string.
  /// </summary>
  /// <param name="value">The string to count.</param>
  /// <returns>Result of number of found occurrences.</returns>
  /// <exception cref="ArgumentNullException"><c>value</c> is a null reference.</exception>
  public int CountOf(string value)
  {
   if (value == null)
    throw new ArgumentNullException(resExceptions.ArgumentNull.Replace("%var", "value"));

   if (value.Length > this.Length || value.Length == 0)
    return 0;

   int count = 0;
   int idx = 0;
   int len = this.Length;

   loop:
    idx = this.IndexOf(value, idx);
    if (idx != -1)
    {
     count++;
     idx++;
     goto loop;
    }

   return count;
  }

  /// <summary>
  /// Indicates whether the current <see cref="String"/> contains only letters.
  /// </summary>
  /// <returns>true if current String is an letter-only String; otherwise, false.</returns>
  /// <remarks>
  /// This method verify whether a <see cref="String"/> contains only letters.
  /// </remarks>
  /// <example>
  /// The following console application example show how to use IsLetterOnly method.
  /// <code>
  /// using System;
  ///
  /// class Program
  /// {
  ///  static void Main()
  ///  {
  ///   string text1 = "Make these tests";
  ///   string text2 = "testing?";
  ///   string text3 = "text3";
  ///   string text4 = "example";
  ///   Console.WriteLine("First example: {0}", text1.IsLetterOnly());
  ///   Console.WriteLine("Second example: {0}", text2.IsLetterOnly());
  ///   Console.WriteLine("Third example: {0}", text3.IsLetterOnly());
  ///   Console.WriteLine("Fourth example: {0}", text4.IsLetterOnly());
  ///   Console.ReadKey();
  ///  }
  /// }
  /// </code>
  /// <br></br>This example returns the following output.
  /// <code>
  /// First example: False
  /// Second example: False
  /// Third example: False
  /// Fourth example: True
  /// </code>
  /// </example>
  public bool IsLetterOnly()
  {
   for (int i = 0; i < this.Length; i++)
   {
    if (!char.IsLetter(this, i))
     return false;
   }
   return true;
  }

I have more...
