Access GET parameters in MVC Controller
提问by Tom
I developed an MVC application and now I need to make some changes. I would like to pass additional parameters and the format of URL cannot be changed. Initially the URL looked like http://url.com/product/1001Now It has to be http://url.com/product/1001?type=1

How do I parse type=1 in my Controller module. Kindly help

You can simply add it to the action method signature:
您可以简单地将其添加到操作方法签名中：
public ActionResult MyMethod(string type)
{
}
Route, QueryString, Form, and other values automatically get bound to action method signatures if the naming matches and a conversion is possible (so int?would also be a valid type for type).
如果命名匹配并且可以进行转换（因此int?也是 的有效类型type），Route、QueryString、Form 和其他值会自动绑定到操作方法签名。
If you don't want to do that, you can always fall back to the ever reliable Request.QueryString[]NameValueCollection.
如果您不想这样做，您可以随时使用可靠的Request.QueryString[]NameValueCollection。
string type = Request.QueryString["type"];
