Sort LINQ result, integers first then strings

Hi all

I am getting back results from a LINQ query. The results are gathered from an object with its own members and public properties which in turn gets its data from the DB. This result is loaded into a combobox I create in code and is attached to a datagridview.

The issue is that it is a combination of integers and strings, such as the following:

1, 2, 3, 4, 5, 6, 7, 8, 9,10,11,12,13,14, 15+, not answered.

The problem is, that with this combination it is sorted as a list of strings. Like this:

1, 10, 11, 12, 13, 14, 15+, 2, 3, 4, 5, 6, 7, 8, 9, not answered.

Is there any way to sort the list so that the integers come first and then the strings, such as the top list indicates?

Thank you

 var temp = "1,+,3,10,5,6,7,8,9,4,11,12,13,14,15,2".Split(",".ToCharArray()).ToList();
var temp2 = temp.OrderBy(new Func<string, int>(orderBy)).ToList();


public int orderBy(string b)
        {
            int value;

            if (int.TryParse(b, out value))
            {
                return value;
            }
            else
            {
                return int.MaxValue;
            }
        }

oops forgot it was VB find VB variant below

Sub Main()
        Dim temp As List(Of String) = "1,+,3,10,5,6,7,8,9,4,11,12,13,14,15,2".Split(",".ToCharArray()).ToList()
        Dim temp2 As List(Of String) = temp.OrderBy(Function(arrayValue) orderBy(arrayValue))
    End Sub


    Private Function orderBy(ByVal value1 As String) As Boolean
        Dim value As Integer
        If (Integer.TryParse(value1, value)) Then
            Return value
        Else
            Return Integer.MaxValue
        End If
    End Function
