Here is a very preliminary implementation of the .NET Framework's StringBuilder class, placed in the System.Text namespace for code compatibility with desktop/mobile C# applications.

This sample code uses an ArrayList and is not performance-optimized.

System.Text.StringBuilder.cs

using System;
using System.Collections;
using Microsoft.SPOT;

namespace System.Text
{
    class StringBuilder
    {
        ArrayList m_charArray = new ArrayList();

        public StringBuilder()
        {
        }

        public StringBuilder(string value) : base()
        {
            Append(value);
        }

        public void Append(string value)
        {
            Char[] charArray = value.ToCharArray();
            Append(charArray, 0, charArray.Length);
        }

        public void Append(char[] value, int startIndex, int charCount)
        {
            for (int index = startIndex; index < startIndex + charCount; index++)
                m_charArray.Add(value[index]);
        }

        public int Length
        {
            get
            {
                return m_charArray.Count;
            }
        }

        public override string ToString()
        {
            return new string((char[])m_charArray.ToArray(typeof(char)));
        }
    }
}
