关闭ASP.NET MVC WebApi中的自动解码

Question

It seems that the FormDataCollection in the ASP.NET MVC Web API auto-decodes the values. Is there a way to turn this off? I am using fiddler to post the following data to my url:

.code=2001&Color=Lam%E9%20Purple

Unfortunately the color is already decoded and results into the following:

Lam� Purple

What I was hoping to get is this:

Lamé Purple

Code used:

[HttpPost]
public HttpResponseMessage PostItem(FormDataCollection collection)
{
    int qty = 5000;
    var response = Request.CreateResponse(HttpStatusCode.Created);
    response.StatusCode = HttpStatusCode.OK;
    if (collection == null)
    {
        response.Headers.Add("Available", qty.ToString());
        return response;
    }

    var item = new Item();
    foreach (KeyValuePair<string, string> keyValuePair in collection)
    {
        switch(keyValuePair.Key)
        {
            case ".quantity":
                item.Qty = Convert.ToInt32(keyValuePair.Value);
                break;
            case ".code":
                item.Style = keyValuePair.Value;
                break;
            case "Color":
                item.Color = keyValuePair.Value;
                break;
            case "Size":
                item.Size = keyValuePair.Value;
                break;
        }
    }

    qty = Repository.GetInventory(item);
    response.Headers.Add("Available", qty.ToString());    
    return response;
}

You seem to be using some specific request encoding, not UTF-8. So adapt your web.config accordingly using the <globalization> element:

<globalization requestEncoding="iso-8859-1" />

or make sure you send correct utf-8 url encoded request:

code=2001&Color=Lam%C3%A9%20Purple
