Question

I read this question: Command Line Parser for .NET.

I thought that was what I was looking for, but the library Command Line Parser Library is not Compact framework friendly…

I REALLY don’t want to write a CL parser and I have been drifting away from the real purpose of my little app because of this unfortunate trial.

Does someone know of a library that fits the compact-framework? (preferably with simplicity and functionality like the one mentioned above)
Does not matter whether version 2 or 3.5

This is what I’m using. I borrowed it from somewhere, but not sure where:

using System.Collections.Specialized;
using System.Text.RegularExpressions;

{
    #region Fields
    private StringDictionary parameters;
    #endregion

    #region Constructors
    /// <summary>

    {
        this.parameters = new StringDictionary();

        Regex remover = new Regex(@"^['""]?(.*?)['""]?$", RegexOptions.IgnoreCase | RegexOptions.Compiled);

        string parameter = null;
        string[] parts;

        // Valid parameters forms:

            // Look for new parameters (-,/ or --) and a
            // possible enclosed value (=,:)
