Pattern to iterate Request Params

My view is not a strongly typed view and I need to iterate through Request Params in the controller action to determine the values posted.

Is there a better way to iterate through the nameValueCollection AllKeys?

I am currently looping through the Request Params and setting values appropriately.

 foreach (var key in Request.Params.AllKeys)开发者_如何转开发
 { 
     if (key.Equals("CustomerId"))
        queryObject.CustomerId = Request.Params[key];
     else if (key.Equals("OrderId"))
       queryObject.OrderId= Request.Params[key];
     //and so on
 }

I see a considerable amount of repetition in this code. Is there a better way to handle this?

Maybe something like this?

queryObject.CustomerId = Request.Params["CustomerId"];
queryObject.OrderId = Request.Params["OrderId"];

Because the NameValueCollection does not provide a Search method and simply by clarify your code, you could do the following:

 foreach (var key in Request.Params.AllKeys)
 { 
      queryObject.CustomerId = key.Equals("CustomerId") ? Request.Params[key] : queryObject.CustomerId;
      queryObject.OrderId = key.Equals("OrderId") ? Request.Params[key] : queryObject.OrderId;
     //and so on ...
 }

Could you not use reflection to getProperties from your query object, then read through them to get the corresponding items from the request.params?

It looks like C# has an equivalent of a Java Map:

If nothing else works, I'd recommend building a Dictionary of key-value pairs, then reading the values out of the Dictionary into the class object.
