在 ASP.NET MVC ，可以访问表单POST数据：

In ASP.NET MVC , one can access the form post data:

推荐答案

的ASP.NET Web API已成为在处理不同的HTTP方案显著更可靠的 - 尤其是流媒体。作为这种只媒体类型格式化通常触摸的内容和具有使内容的连贯性。

ASP.NET Web API has become significantly more robust in dealing with different HTTP scenarios - especially streaming. As such only media type formatters normally touch the content and have to make a coherence of the content.

在ASP.NET MVC中，应用程序/ x-WWW的形式urlen codeD 内容类型是一等公民（尤其是对待，因为这是的POST请求的95％的内容类型），我们有 FormsCollection 来提供接入字典访问，当它被定义为输入参数。

In ASP.NET MVC, application/x-www-form-urlencoded content type is a first class citizen (and treated especially since this is the content type of 95% of the POST requests) and we have the FormsCollection to provide dictionary access in access, whenever it is defined as an input parameter.

在ASP.NET的Web API，应用程序/ x-WWW的形式urlen codeD 是另一个内容类型，并应该是其MediaTypeFormatter阅读。这样的ASP.NET Web API无法做出关于形式的任何假设。

In ASP.NET Web API, application/x-www-form-urlencoded is yet another content type, and supposed to be read by its MediaTypeFormatter. As such ASP.NET Web API cannot make any assumption about the Forms.

在的ASP.NET Web API通常的做法是重新present的形式的模型，因此媒体类型格式反序列化。另一种方法是定义动作的参数为的NameValueCollection ：

The normal approach in ASP.NET Web API is to represent the form as a model so the media type formatter deserializes it. Alternative is to define the actions's parameter as NameValueCollection:

public void Post(NameValueCollection formData)
{
   var value = formData["key"];
}
