 ASP.Net C#  Dropdown

Rate this:

<asp:DropDownList ID="ddlAge" runat="server"/>


Label ages = (Label)e.Row.FindControl("Ages");


//The value ages returns is different every time but it will be in this format

// 3 - 11

So i would like to grab the 3 from the left of the dash and then grab the 11 from the right of the dash and populate my dropdownlist with the values of 3,4,5,6,7,8,9,10,11 if possible just not sure how to go about doing this.

You can do this:


private IEnumerable<int> GetAgesBetween(string agesText) {

    var parts = agesText.Split('-');

    var start = int.Parse(parts[0].Trim());

    var end = int.Parse(parts[1].Trim());

    return Enumerable.Range(start, 1 + end-start);


You can use that method to retrieve the numbers and use them to populate the drop down list.


Hope it helps

This is in VB, but you can convert it in C#. This is just so that you get an idea as to how you can approach this problem. Here is the code:


     Dim ageData() As String = ages.split("-".ToCharArray())


     If ageData.Count = 2 AndAlso IsNumeric(ageData(0).Trim) AndAlso IsNumeric(ageData(1).Trim) Then

        For i As Integer = CInt(ageData(0)) To CInt(ageData(1).Trim) Step +1



     End If
