使用回调和RegEx方法将JavaScript代码转换为c#中的等效代码

我有下面的JavaScript代码，返回一个与用户命令相关的函数回调，用户命令可以以不同的方式使用，因此需要RegEx:

(function (undefined) {
  "use strict";
  var root = this;
  var commandsList = [];
  var debugStyle = 'font-weight: bold; color: #00f;';
  // The command matching code is a modified version of Backbone.Router by Jeremy Ashkenas, under the MIT license.
  var optionalParam = /'s*'((.*?)')'s*/g;
  var optionalRegex = /('('?:[^)]+'))'?/g;
  var namedParam    = /('('?)?:'w+/g;
  var splatParam    = /'*'w+/g;
  var escapeRegExp  = /['-{}'[']+?.,'''^$|#]/g;
  var commandToRegExp = function(command) {
    command = command.replace(escapeRegExp, '''$&')
                  .replace(optionalParam, '(?:$1)?')
                  .replace(namedParam, function(match, optional) {
                    return optional ? match : '([^''s]+)';
                  })
                  .replace(splatParam, '(.*?)')
                  .replace(optionalRegex, '''s*$1?''s*');
    return new RegExp('^' + command + '$', 'i');
  };
  var registerCommand = function(command, cb, phrase) {
    commandsList.push({ command: command, callback: cb, originalPhrase: phrase });
      root.console.log('Command successfully loaded: %c'+phrase, debugStyle);
  };
root.fonixListen = {
    addCommands: function(commands) {
      var cb;
      for (var phrase in commands) {
        if (commands.hasOwnProperty(phrase)) {
          cb = root[commands[phrase]] || commands[phrase];
          if (typeof cb === 'function') {
            // convert command to regex then register the command
            registerCommand(commandToRegExp(phrase), cb, phrase);
          } else if (typeof cb === 'object' && cb.regexp instanceof RegExp) {
            // register the command
            registerCommand(new RegExp(cb.regexp.source, 'i'), cb.callback, phrase);
          }
        }
      }
    },
    executeCommand: function(commandText) {
      for (var j = 0, l = commandsList.length; j < l; j++) {
        var result = commandsList[j].command.exec(commandText);
        if (result) {
          var parameters = result.slice(1);
          // execute the matched command
          commandsList[j].callback.apply(this, parameters);
          return true;
        }
      }
    }
  };
}).call(this)

下面是一些命令:

  var commands = {
    'hello :name *term': function(name) {
      alert('hello '+name+'');  // i.e. consider *term as optional input
    },
   'items identification': {
         'regexp': /^(What is|What's|Could you please tell me|Could you please give me) the meaning of (TF|FFS|SF|SHF|FF|Tube Film|Shrink Film|Stretch Hood|Stretch Hood Film|Flat Film)$/,
         'callback': itemsIdentification,
   },
   'ML SoH': {
         'regexp': /^(What is|What's|Could you please tell me|Could you please give me) the (stock|inventory) of ML$/,
         'callback': mlSOH,
   },
    'Report stock on hand': {
         'regexp': /^(What is|What's) (our|the) (stock|inventory|SoH) of (TF|FFS|SF|SHF|FF|Tube Film|Shrink Film|Stretch Hood|Stretch Hood Film|Flat Film)$/,
         'callback': SoH,
        },
     'Basic Mathematical Opertions': {
               // ?'s? can be used instead of space, also could use /i instead of $/,
                'regexp': /^(What is|What's|Calculate|How much is) (['w.]+) ('+|and|plus|'-|less|minus|'*|'x|by|multiplied by|'/|over|divided by) (['w.]+)$/,
                'callback': math,
              },
  };

应用运行时，执行addCommands命令，根据用户输入的命令，执行executeCommand命令。

上面的工作对我来说很好，但我正在转向c#，对它非常陌生，所以寻求帮助，至少是c#中的一些功能和工具的指导，可以帮助我编写类似于上面的东西。

关于我尝试做什么的更多细节，实际上我有一个表单，用户通过使用html5语音API输入他的命令，API将此语音转换为文本，然后将此文本提交给我的应用程序，我的应用程序工作从查看此文本开始，试图使用ReqEx找到所需的命令，然后执行与此输入命令映射的编程函数/回调。
