How Do I Get The Returned Id From The Store Proceedure In Asp C#?

my store proceedure gets the id:

 
 
CREATE PROCEDURE createpost(
 @userID integer,
 @categoryID integer,
 @title varchar(100),
 @newsdate datetime,
 @story varchar(250),
 @wordcount int
)
 as
DECLARE @newNewsID integer
Insert Into TB_News(UserID, CategoryID, title, newsdate, StoryText, wordcount)
Values (@userID, @categoryID, @title, @newsdate, @story, @wordcount)
SELECT @newNewsID = @@IDENTITY  

 
then im calling it in the asp:
 
  con = new SqlConnection ("server=declt; uid=c1400046; pwd=c1400046; database=c1400046");
  con.Open();  
      
  cmdselect = new SqlCommand("createpost", con);
  cmdselect.CommandType = CommandType.StoredProcedure;
  
  
  cmdselect.Parameters.Add("@userID", userID);
  cmdselect.Parameters.Add("@categoryID", categoryID  ); 
  cmdselect.Parameters.Add("@title", title.Text ); 
  cmdselect.Parameters.Add("@newsdate", newsdate.Text ); 
  cmdselect.Parameters.Add("@story", story.Text );  
  cmdselect.Parameters.Add("@wordcount", "1" );
  
  
  int valueinserted = cmdselect.ExecuteNonQuery();
  
  
  Response.Redirect("http://declt/websites/c1400046/newpicture.aspx?id="+valueinserted); 
  
  con.Close();
 
as you can see im using the valueinserted but thats just returning 1, but im guessing that means it sucessful. but i want the id of the new record! any idea how ?
