Assuming your pages will all be .aspx:
(?<=/)\w+.aspx(?=\?)

In C# use:
@"(?<=/)\w+.aspx(?=\?)"

---Edit---
If you want to catch more characters, you can modify the bold part of the expression below:
(?<=/)[\w\.]+.aspx(?=\?)

The second regex will also match dots in the part preceding .aspx.

([a-zA-Z.]+)(?=\?)

You can use this.Just grab the first group.See demo.

Have a look at Uri.AbsolutePath

So can do 

Path.GetFileName(Request.Url.AbsolutePath)

string str = "/test1/Pages/Request/test.aspx?id=-1";
string page = str.Substring(str.LastIndexOf('/')+1, str.IndexOf('?')-str.LastIndexOf('/')-1);
