syntax to return a number of results per page - linq

Question

I have this linq statement that returns result and i wanted to add the specifications of how many items are displayed per page. I know the default is 10 per page how can i change it to 40?
var _roster = DataCBase.StoredProcedures.GetUser<Users>(userID, r => new Users
{
Name = RosterColumnMap.Name(r),
Email = RosterColumnMap.Email(r)
});
Get User
public virtual IEnumerable<T> GetUser<T>(int userId, Func<IDataRecord, T> modelBinder, int resultsPerPage = 10, int pageNumber = 1)
{
if (userId < 1)
throw new NullReferenceException("The sectionId cannot be null, when retreiving an element");
if (resultsPerPage < 1)
resultsPerPage = 1; // enforce bare minimum result set
if (pageNumber < 1)
pageNumber = 1; // enforce one-based page numbering
SqlCommand _command = new SqlCommand("dbo.GetUser");
_command.CommandType = CommandType.StoredProcedure;
_command.Parameters.Add(new SqlParameter { ParameterName = "userId", SqlDbType = SqlDbType.Int, Value = userId });
_command.Parameters.Add(new SqlParameter { ParameterName = "resultsPerPage", SqlDbType = SqlDbType.Int, Value = resultsPerPage });
_command.Parameters.Add(new SqlParameter { ParameterName = "pageNumber", SqlDbType = SqlDbType.Int, Value = pageNumber });
return DbInstance.ExecuteAs<T>(_command, modelBinder);
}

Neither Linq nor entity framework have any default number of records 'per page'. But since your GetUser function includes a resultsPerPage parameter, you can just do this:
var _roster = DataCBase.StoredProcedures.GetUser<Users>(userID, r => new Users
{
Name = RosterColumnMap.Name(r),
Email = RosterColumnMap.Email(r)
}, 40);
To limit the number of results in Linq use the the Enumerable.Take method:
var _roster = DataCBase.StoredProcedures.GetUser<Users>(userID, r => new Users
{
Name = RosterColumnMap.Name(r),
Email = RosterColumnMap.Email(r)
}).Take(40);
