Get a routing value from the URL.

Dec 20, 2012 03:25 PM|LINK
I would like get the last value from the this URL:
```
/Panel/SignalHistory/9140
```
This is the URL before routing:
```
/Panel/SignalHistory?EntityId=9140
```
How would I go about this? Thanks.

In your action , you can use EntityId as parameter:
```
public ActionResult(int EntityId)
{
   return View();
}
```
Or you can get it from Request.QueryString
```
public ActionResult()
{
   var entityId=Request.QueryString["EntityId"];
   return View();
}
```

This actually doesn't work. I get an error that index for Request.Query string is out of range.

Just to clarify, it works when using a regular GET type URL (eg, /Panel?EntityId=9140), but not once it is routed it (eg, /Panel/SignalHistory/9141) throws the error.

Just to clarify, it works when using a regular GET type URL (eg, /Panel?EntityId=9140), but not once it is routed it (eg, /Panel/SignalHistory/9141) throws the error.

by default the route table puts route parameters into a variable called Id. If you want to change that you can make changes in the RouteConfig.cs file.

To get it working as it, simply pass a variable called Id to your action method.
```
public ActionResult SignalHistory(int id){
  // id now should be 9141 or whatever is in the URL
}
```

You can use parameter id in your action as below :
```
public ActionResult SignalHistory(int id)
{
    return View();
}
```
```
You will be get value of id . /Panel/SignalHistory/9141
```
```
 
```

You could also try this:

The syntax differs slightly between MVC 3 and MVC 4.
```
ViewContext.Controller.ValueProvider["id"].RawValue
```
